It’s very helpful when everyone has a basic knowledge of Bed Bugs.
Bed Bug Dogs K9 are extremely helpful and an important part of our Bed Bug Program at Clark Pest Remedy. If you live in Georgia or the Hilton Head, SC Area give us call at 770-957-1915 and we can try to answer your questions to see if this would be helpful to you.
The Dogs enjoy working every day. They can distinguish between bed bugs and other insects very easily. They know the difference just like we know red and blue. As humans we think in terms of vision because that is our main sense. “You should see what I saw yesterday”. “I saw it that way.” ” See what you can do about it”.If the dogs could talk they would say “you should have smelled what I smelled yesterday”
These dogs are like little biological x-ray machines that are portable and have great personalities. They help us to quickly determine which areas are infested and which are not, making remediation much more accurate and thorough.The dogs are paired with a handler and trained to work daily with their “Best Friend” This handler is responsible for their every whim. Feeding, Grooming, Training constantly, Safety. But most of all there is a bond that develops that makes the dog want to please their handler. Yes they are rewarded for finding them just as we are rewarded for work. It is like a fun game for the dogs and they are proud of their finds. We have many customers that find them fun to watch. We do many High-Rise, Assisted Living, Hotels where the dogs can inspect a room in just a few minutes with accuracy. Its not uncommon for them to complete 40-60 units a day. Heat is a factor as we must keep the dogs cool. We are very mindful of the animals safety and living conditions. The handlers always fall in love with their dogs. This is because they watch the dogs perform so well and realize that they are solely working to please them. It is only natural to immensely love them also. It is not uncommon for a dog to follow their handler everywhere they go.They usually don’t want their handler out of sight. So they tag along everywhere, just being a regular dog when off-duty. After the K9 does their job we are making notes to help us do a great job of elimination.
We use Thermal Remediation Heat Equipment to eliminate bed bugs. Bed Bugs have no resistance to temperatures above 118 degrees. We use electric equipment (No Propane) and create our own power with installed generators in our trailers or trucks.It is typical for a Heat Treatment to take 5-7 hours to complete. There is some preparation that needs to take place by the resident. If you have a bed bug issue or you think you may have a problem and want the K9 service to be sure give us a call at 770-957-1915 and we will get the ball rolling to get you bed bug free and keep it that way.
Bed Bugs can be a major concern in a Senior Living Environment. With all the people living closely together it makes it a challenge to keep Bed Bugs under Control. Just their hitchhiking nature makes them a constant problem. With older folks it’s also quite common for them to move in used furniture or clothing that’s infested. They also have visitors that sometimes have bed bugs at their homes. Then you have all the healthcare workers and employees that work there. Unfortunately with old age the eyesight is sometimes not as good as it was. I have seen Seniors that had them pretty bad but they just weren’t seeing them.
This is an adult bed bug that I found crawling on the carpet near a bed in Atlanta.
Here are a few protocols we recommend and provide.
Education: We provide basic bed bug training for your employees, tenants and management. It’s much better when everyone knows more about bed bugs and what they look like. Also all the different ways you can bring them in. There are always a lot of good questions.
We do a Power Point type presentation with many pictures and information to share with tenants, maintenance, and management.
K9 Bed Bug Dogs: We have 3 bed bug dogs at this time. We use them on sweeps throughout facilities determining the absence or presence. We can typically do 60-100 units in one day using all 3 dogs. After the inspection is completed you will know which units have an issue and which do not. This is a fabulous way to maintain control in your facility. Some get a bit nervous but once they see the dogs perform and the results,most want us to start doing sweeps quarterly. Contact us for pricing on facilities sweeps.
Here is Aaron with his handler William Hudson responding to bed bugs in a couch in Atlanta
Thermal Remediation Heat Treatments for Bed Bugs:
Our Electric Heat Systems Trucks and Trailers have built-in generators to provide the power for the heaters. The heaters are [placed inside strategically and it usually takes about an hour to heat the area to above 120 degrees. During this time we set up beds, couches,etc and we also do some containment spraying of host areas and outlet plates. We finish up heating at 130-135 degrees and hold the heat for 3-4 hours or more with fans spreading the heat around evenly.
We treated an entire floor of a Senior facility in Atlanta.
Aprehend: Is a new Biological Material used to help control bed bugs. We use this in some situations. Not a pesticide. It is actually a fungii that is bottled and used to create barriers that bed bugs would have to go through to reach a host.
We can also give a warranty with our work.
If you have any questions or would like more information on managing bed bugs in a Senior Living Environment please contact us at 770-957-1915
We have plenty of references and will be glad to supply you with some.
We service the Atlanta, Macon, Savannah, Athens, Hilton Head, Brunswick, Statesboro, Marietta, Gainesville Areas.

What Steps should be taken to properly manage a facility such as this for Bed Bugs ?
Senior Living Tenant Training Class
This is often times overlooked. We offer free educational classes to make sure the staff/and or tenants know the basic information they need to know to identify a problem and keep it from spreading throughout a facility. Some management get a little nervous but they always are glad they made the decision to go ahead with it. I also have some training classes on my youtube channel for small groups or single employees. This can be done with a cup of coffee and a bisquit in just a few minutes.
Bed Bug Detection Dog
Our K9 Team can inspect one room, one home, a whole facility or high rise. This is the most efficient and accurate way to determine areas of activity
Bed Bug Dog Training Wheel
The dogs are constantly calibrated much like a scientific instrument. Their sense of smell is thousands of times more acute than ours. With a well trained human inspector/handler the team together can do some wonderful detection work and save money and spread.

Couch Bed Bugs
Excrement marks, skins, or live bugs can be found in many areas around where people sleep, or gather.
Designing the proper treatment plan is based on detection and is critical to the success of maintaining a Bed Bug Free Environment.
3. Bed Bug Treatments
We use Thermal Remediation Heat Equipment. This is specially engineered Electric Heat Equipment built for this type of treatment.
This is the most effective method for elimination of Bed Bugs. Why ? Because Bed Bugs have no resistance to temperatures above 120 degrees. They have a lot of resistance to the pesticides on the market today. And it fills the entire area up with the temperatures giving them no place to hide.
Bed Setup for Heat Treatment
We also use some pesticides around the edges of the room for containment. Dusting the wall plates is also important.
4. Encasements for mattresses and box springs.
Mattress and Box Springs Encasements
Encasements disallow future access to the mattress and box spring. It also serves as a secondary line of defense against any survivor bugs or eggs. With some materials being used it also helps protect you from exposure to any insecticides that may have been used. Not only by us but also by the tenant or homeowner. It is very common for self treating to occur before we are called in.
We install these at the end of the treatment process.
5. Follow up Inspection and Monitoring. After treatment has completed a monitoring program with K9 Inspections or Visual Monitoring should be set up in order to be proactive in this area.
Call Us at 770-957-1915 to discuss starting a Bed Bug Program for your facility. We have a program from start to finish. Bed Bugs are a manageable insect to control but you must be proactive or you can find yourself with a really large problem. We have had Senior High Rises call in with 40-50 infested units. This is not an enjoyable situation for anyone involved.
We can help you with ideas to help manage your situation efficiently.
We received a call from another pest control company requesting to use the Sensor Dogs at a large office building where some bed bugs were found. The K9 team went out at night and inspected a large area with around 80 cubicles. The dogs traced the scent down to about 4 cubicles. The handler could not find any live bed bugs but told them there is something going on in this area, which was about a 4 cubicle area. The employees in that area had their homes inspected and found one with a fairly heavy bed bug infestation. The company paid for her home to be treated and let them pay back weekly payments. I really think this was a great idea. Problem solved for now.

What Do You Do ?
Most of the time they are being brought in by employees with a bed bug infestation at their homes. How can you determine where they are coming from ? What is the risk to other employees and the business. The Business needs to pay attention and act quickly ! I would recommend that you consider a Sensor Dog K9 inspection to see if they can at least pin it down to an area.
Abby the Bed Bug Dog – Atlanta
Our dogs can assist in determining the location of live bed bugs in an office environment. There is usually not a lot of preferred nesting areas in an office. No one sleeps there 😐 Most office furniture is not as preferred as homes and home furniture. Over the years we have been called out for many office settings. Many times it’s not bed bugs. If it is a bedbug it’s usually a “drop off” from an employee with a bed bug problem at their home. If you serve the public, clients can come in and leave some behind. We see this in places like Dialysis Centers, Doctors office, Dentas waiting areas, etc. This is also how hotels become infested so don’t unload on them too hard. Until it is brought to someone’s attention nothing is usually done. While it’s difficult to prevent bed bugs, there are proactive steps that can be taken.

Communication with employees ( Discuss prevention.)
Get professional help by specialists.
Get a Sensor Dog inspection for accurate evaluation.
Treatments if needed must be precise and thorough. In some cases heat may be a good option however if someone is bringing them in it very easily can duplicate. A residual material and monitoring is needed in these cases. It can be traumatic for those that don’t understand the bug. You probably are more exposed at a movie theatre than your office. A controlled environment has a better chance of succesful control.

Bed Bugs Can be a Difficult Problem in Senior Living Facilities !
Ad in 1940’s for Bed Bug Sprays
Senior Living can be a difficult situation to control bed bugs. Large numbers of people living closely together in one building in itself is hard to control. It is common for them to bring in used furniture or used clothing which can lead to bed bugs in the building. Besides that they can have visitors that have infestation at their home. Healthcare workers may be infested and spread them into facilities. Or vice versa.
With the mounting incidence of bed bugs in homes, apartments and businesses, discovering them early removes the possibility of “infestations” from building. All public or high traffic businesses and multi-unit dwellings need to be doing regular inspections for bed bugs and here’s why:
LIKE TRYING TO FIND A NEEDLE IN A HAYSTACK
I’m sure at one time or another in your life you’ve heard the expression, “Like trying to find a needle in a haystack”, and that is exactly what it’s like trying to find a single bed bug introduction, small amounts or bed bugs eggs in any environment. The bed bug is like the needle and the environment is like the haystack.
That is why there are so many more infestations popping up all over. People may suspect a problem but can’t find evidence of such. It is then that they play the wait and see game and before long, a bed bug infestation has built and they are taking bed bugs with them to work and school or anywhere they go.
The truth is, no matter how hard we try as humans, our visual inspections pales in comparison to the remarkable scenting ability of a detection dog.
In early stages of bed bugs, or when they’re are first introduced, the size and reclusive nature of the bed bug places them in inaccessible areas where unless we had x-ray vision we just could not detect where they are hiding. In addition, human inspections require extensive knowledge of the bug, the use of a magnifying glass and a bright light to see in dark crevices, while tearing apart and disassembling furniture. This process is extremely time consuming in such that a person can expect a professional to be in their homes for well over an hour or more. Even after a careful examination, they still may not have found the area where they are hiding.
To give you an example, pretend you’re asked to hide a straight pin somewhere in your living room and ask a friend to find it. You could have pulled a cushion from your couch and penetrated it deep along a seam in the corner or behind the cardboard of a wall hanging or painting. Alternatively, maybe you slipped it through a crack behind the baseboard and it fell through. Finding it would literally take hours and in most cases, they would never find it!
Now, if they told you it was somewhere in the vicinity of the chair in the right-hand corner of the room, you could focus your efforts in a few square feet vs. inspecting the whole room and all its contents and it would cut your inspection time down. Again, just because you know the area doesn’t mean that you will find it if it is hidden behind that baseboard.
HUMAN INSPECTION vs. DETECTION DOG COSTS
Knowing that inspecting for bed bugs takes a tremendous amount of time to do it right, the cost for doing a proper inspection could range anywhere from one hundred dollars on up. A human inspector with around 35% accuracy couldn’t possible do a comprehensive inspection in fifteen to thirty minutes and can miss hide harborages easily leaving you with bed bugs unnoticed. On the other hand, although it may cost you a bit more, but detection dogs can sweep the same areas in a fraction of the time it takes a professional, have a much higher accuracy rate and show you exactly where the bugs are hiding for a much easier and efficient treatment.
Spending a little more money upfront will save you from expensive treatments later should they go unnoticed and build up to infestation levels!
Luckily, bed bugs put off a scent, which these dogs are trained to detect. They pick up the scent cone and when they smell where bed bug’s hidden harborages are, they signal an alert of their find to the handler. This is especially valuable in early stages when treating for bed bugs stops infestations from building.
Because every insect has a different nature and tolerance to what we use to eliminate them, they require different treatment elimination processes. You need to find and verify the insect in question in order to know which treatment to use. (Treatment used for cockroaches doesn’t work for mosquitoes and so on)
Unlike many other insects, there is no preventative insect spray for bed bugs. Although the use of CimeXa in wall voids, electrical outlets and cracks and crevices has shown to be affective in stopping them from getting to far should they cross those barriers.
VERIFYING DETECTION DOG ALERTS
Before the application of any professional treatment, the industry requires verification of the insect at question. Once the dog alerts on a particular area, it is up to the handler to do a comprehensive inspection to expose evidence of the alert.
If they are not able to visually verify the dogs alert, it doesn’t mean the dog was wrong or that it was a false alert, it means that there may not be enough bed bugs to find visual evidence or that they are well hidden behind baseboards, in wall void or in places where they can’t see into or behind. This doesn’t mean they are not there. During this time, they will suggest monitoring for activity and reschedule an inspection at a later date.
On or off the job, these dogs are continually trained by their handlers using live bed bug specimens to keep them keen on the scent of live bed bugs or viable eggs.
WHAT TO WATCH OUT FOR WHEN CHOOSING A TEAM
In every industry, there are do-gooder’s and those who take advantage of others. Watch out for those who say they can sweep 70 to 100 rooms with one dog in a single day. Detection dogs require breaks for resting their nose, potty breaks and a snooze.
PEACE OF MIND
The most rewarding part of regular inspections is the peace of mind it gives you. Whether in your own home, business or multi-unit properties, regular bed bug detection dog inspections can help keep from infestations from ever happening!
We have K9 inspectors and Thermal Remediation Equipment designed to eliminate Bed Bug infestation.
Here is our Youtube video that should be helpful for you to identify bed bug infestation. If you are a property manager or maintenance person it is good to know at least the basics of bed bugs so that you can recognize any issues early before they spread. If you would like to use this video to help train your employees feel free to do so. I will be adding more as time goes on. If you have any questions please call us at 770-957-1915 and an expert will contact you shortly. We specialize in Bed Bug Detection and Thermal Remediation Electric Heat Treatments.
We do a lot of work in Senior High Rises and Apartments in Metropolitan Areas. These situations can be frustrating for everyone involved. In some cases the landlord takes financial responsibility for elimination. In many cases the tenant is held responsible which raises many concerns.
1. Affordability 2. Communicating that they have an issue due to cost. 3. Do it yourself treatments – Safety – Inneffectiveness 4. While trying to do it themselves they spread to other units 5. Discarding of furniture (Not wrapping and spreading) 6. Other Tenants picking up said discarded furniture
Adult Bed Bug
There are many proactive ways to help keep bed bugs under control in these situations.
1. Education – We provide Classes for Tenants and Staff to familiarize them with what they look like and how they are transferred.
2. Inspect Furniture before new move-ins.
3. Have unit inspected by a professional right after a tenant moves out. Get inspection report with findings. If not there can be a battle if there are bed bugs found within the first few months of a new tenant. The tenant will claim they were there when they moved in. Landlord can’t prove they weren’t.
4. Let the tenants know that if they report a bed bug situation the landlord will handle it and make the tenant pay affordable payments until it is paid.
5. Repeat (numerous) offenders at some point will be evicted if not reported.
Free Bed Bugs ?
Tenants need to realize that Bed Bug Treatments are expensive and Landlords don’t want them in their properties. Landlords need to realize that in many cases the tenant really didn’t do anything wrong. Through education the tenants can be taught what not to do when it comes to bed bugs.

Think Like A Bed Bug by: Denise Donovan (IBBRA.org)
I’m flattered when seeing PCT Magazine’s article using the title of my early 2012 book, “Think like a Bed Bug”.
When I was deciding on the title, as part of my entomological research, I knew that in order to combat any insect you need to know their traits and behavior in order to outsmart them and thus “Think like a Bed Bug” became the name of my book.
Thanks Mike for addressing this so well.
Infestations left untreated or not treated correctly because of not “understanding” the insect seem to be one of the biggest causes of the continued spread within multi-unit properties. Managing bed bugs takes more than a chemical or heat treatment; it takes “knowing thy enemy”.
‘Think’ Like a Bed Bug
Bed Bug Supplement
“Know thyself, know thy enemy. A thousand battles, a thousand victories.” — Sun Tzu, the Art of War
January 4, 2016 – Sydney E. Crawley, Michael F. Potter and Kenneth F. Haynes
Around 512 B.C., Sun Tzu and the brightest military minds agreed: to defeat the enemy, you must know the enemy. Fast-forward to today and researchers and pest managers alike are coming to the realization that there are no “silver bullets” in today’s war against bed bugs. Nonetheless, scientists around the world continue to study bed bug biology and behavior in hopes of finding chinks in their seemingly impenetrable armor. The intent of this article is to give practitioners a better feel for what everyday life is like if you’re a bed bug, and how some of these insights may lead to improvements in management.
BIOLOGY BEGETS BEHAVIOR. To decipher bed bug behavior one must first know the traits that allow them to survive and produce offspring. The most critical adaptation for survival is their ability to feed exclusively on blood. After hatching, bed bugs molt, shedding their exoskeleton five times before reaching adulthood. Each of these five progressions requires that the insect take another blood meal. Bed bug nymphs seemingly behave similarly to adults, although more research should focus on juvenile bed bug behavior. We do know that young nymphs are more prone to desiccation and may have dispersal habits that differ from adult bugs.
Once a bed bug is an adult, they will need to continue to take blood meals in order to lay eggs and produce offspring. Feeding occurs during times when the host (usually us) is least likely to be aware of their presence. Thus, they forage for blood when we are fast asleep, and their bites are not easily detectable. The period during and directly after feeding is often when mating occurs. Mating behavior among bed bugs is traumatic for females, with males piercing their abdominal cavity directly. Each bout of feeding puts a female at risk for roughly five traumatic inseminations, not necessarily from the same male “suitor.” These excessive mating attempts can reduce female lifespan. Mated female bed bugs lay approximately 120 eggs (on average) in their lifetime, enabling infestations to grow rather quickly. These biological principles give rise to predictable behaviors displayed in the field, some with implications for management.
Bed bugs characteristically form dense, hidden aggregations in small spaces.
LOVE THE ONES YOU’RE WITH. If you’re a bed bug, there aren’t many opportunities for privacy. From the moment a pinhead sized “neonate” emerges from an egg, other bugs both younger and older aren’t far away. In fact, scores of individuals may be sharing a crevice no wider or deeper than a toothpick.
The tendency for bed bugs to form tightly packed, dense, hidden aggregations is one of the most striking behaviors they exhibit. Within these aggregations, a bed bug will grow, defecate, and mate with other bed bugs that are typically from the same maternal lineage. This aggregation behavior represents a significant advantage to a parasite that feeds on a host that routinely sleeps in the same place. Many of the close relatives of bed bugs, including bat and bird bugs, share the same adaptation.
When deciphering bed bug behavior, it helps to think in terms of what may be in it for the bug. For instance, the tendency of bed bugs to form aggregations would not exist if there were not some intrinsic benefit. Recent studies have revealed that bed bug nymphs reared in groups develop faster than nymphs reared in isolation (Saenz et al. 2014). It also has been shown that bed bugs in an aggregation avoid dehydration much more effectively than bed bugs held alone (Benoit et al. 2007). This probably helps account for the remarkable length of time that bed bugs can survive without taking in any blood — for months, or even more than a year in cooler environments. Seemingly, bed bugs that stick together may fare better when the going gets tough and hosts are scarce. Other benefits that have been proposed but not verified include the ability to discourage predators (although predation on bed bugs in our homes is relatively rare), the transfer of beneficial microorganisms between group members, increased opportunities for mating, or caring for offspring. These behaviors exist in other insects that aggregate, but have not been confirmed for bed bugs.
Bed bugs detect chemical cues in the environment with their antennae.
Although aggregating has clear benefits, it is possible to have too much of a good thing. There are also potential risks associated with large aggregations. For instance, the larger the aggregation gets, the more likely you are to become conspicuous to humans trying to kill you. Additionally, competition for mates might become fiercer within these large groups. Perhaps your risk of infection from fungi or other pathogens rises as feces and other debris accumulate in increasingly crowded areas? These potential risks may explain why some researchers have observed a “cap” to aggregation sizes, which may help us to one day predict why and when bugs within an aggregation may leave their current setup for something better (more on this later).
CONVERSATIONS WE CAN’T HEAR. Much progress has been made in our understanding of why bed bugs aggregate. For a bed bug to detect the presence of another bug and begin the formation of a group there is communication between them. Insects often send messages to one another to initiate a social interaction. An effective message will be received and interpreted by another bug and a behavioral response, such as aggregating, will follow.
Although not apparent to us, bed bugs are “talking” in this manner all the time. These conversations are chemical in nature, and since the chemical message benefits the signaler and the receiver — we call them pheromones. Pheromones are the main way insects communicate, and those that cause bed bugs to aggregate are appropriately termed “aggregation pheromones.” Bed bugs detect these compounds with receptors located on their antennae, which serve as the olfactory organ for most insects. Although the social nature of bed bugs cannot be compared to the caste systems of termites or ants, it should be clear that bed bugs do in fact have numerous important social interactions within aggregations.
Bed bugs have few natural enemies, but sometimes are eaten by spiders and ants.
Aggregation pheromones are deposited by bed bugs when they find a suitable place to call home — the seam of a mattress or recliner, crevices of a nightstand, etc. We know that there are two parts to a successful “aggregation message” to other bugs.
One part of the message is released into the air with some of these compounds coming from the scent glands. The other part is deposited directly onto the surface through feces or shed skins and persists in the environment for longer periods of time. All bed bugs respond to the aggregation pheromone.
On substrates, five volatile compounds within the feces or on shed skins attract bed bugs to safe places, while a longer-lasting component (histamine) causes bed bugs to stop and remain there (Gries et al. 2015). The arresting power of the compounds is so powerful that they cause bed bugs to rest on surfaces treated with certain insecticides, which otherwise they may find repellent (Romero et al. 2009). Once the bed bugs have found a suitable place to hunker down, the behavior is reinforced through touch; similar to cockroaches, bed bugs respond positively to contact from other bugs and from the walls of small spaces.
Bed bug feces contain a pheromone that causes bed bugs to aggregate.
LEAVE THE ONES YOU’RE WITH. Although bed bugs are considered sedentary creatures, there are many times when they leave the security of their aggregation. Bed bugs move when there’s a perceived threat, when they need to feed, or when their current location is no longer hospitable — such as when a host is no longer available.
Bed bugs tend to respond negatively to light so they may move away from light toward darkness. There is also some evidence to suggest that in addition to light and dark detection, bed bugs may use vision to differentiate between darker and lighter harborages, with a preference for darker colors. Understanding the mechanisms and triggers of bed bug movement will help in preventing their spread from one location to another.
To better understand bed bug dispersal we need to ask ourselves, “Why would it benefit a bed bug to leave home?” A bed bug on the move risks death when detected by the host. Even without insecticides, humans are a lethal threat and perhaps their greatest risk of a quick demise. Wouldn’t it be wiser to remain inconspicuous? Unfortunately, for us, bed bugs have finely tuned adaptations that allow them to avoid periods of time where their movements would be riskiest.
Bed bugs require blood to grow and reproduce, so adaptations for finding a host and taking a blood meal are critical for their survival. Feeding strategies have been fine-tuned over the eons that bed bugs and their buggy ancestors have been parasitizing humans, so they’ve become experts at the process. Every time a bed bug feeds they risk detection and death, so quick movement to and from the host is of paramount importance. Like many other animals, bed bugs follow a circadian rhythm, exhibiting predictable behaviors that occur cyclically over 24-hour periods. For bed bugs, these changes are set by the change from light to dark and in fact, bed bugs move more in the dark than in light even in the absence of host cues.
This cyclical pattern includes seemingly random movements that are not directed towards or away from the host, but are, nonetheless, the first step to finding their next meal.
Once they’re triggered by nightfall to move away from aggregations, research indicates that carbon dioxide emission is one of the first cues that stimulate bed bug movement from a distance. As the bug gets closer to a warm-blooded host, their movement becomes more directed as heat is detected. Bed bugs have specialized sensory structures on their antennae that can detect even small fluctuations in temperature. However, bed bugs are not akin to “heat-seeking missiles” — it takes time and many blundering movements based on heat gradients and elevated levels of carbon dioxide to make their way to the host. The exact distances over which bed bugs use heat and carbon dioxide to fine tune their movements are still in question. Determining whether these directed movements start at a few feet or a few inches from the host requires following the movements of individual bed bugs before feeding.
Bed bugs spotted by humans often suffer a quick demise.
The research regarding attraction to human odors is also controversial. Early research suggested that skin odors could have a subtle effect on host attraction, but not nearly as pronounced as the effect of heat. These results should be taken with some caution, as other studies have actually shown that human perspiration is repellent. More work will be necessary to tease apart the role of human odors on bed bug host-seeking. It seems safe to conclude, however, that heat, carbon dioxide and darkness are definitely triggers for most bed bug movement. It could be that some host cues provide directional information (such as heat, which our lab observed directional orientation within 12 inches; Haynes et al. 2008), while others such as carbon dioxide function more as “activators,” intensifying random movements that are innately turned on each night. (See figure above.)
DO NOT DISTURB. Not all bed bug movements are meant to help them find food; they also may move or disperse in response to threats. Bed bugs emit alarm pheromones when they are disturbed. Interestingly, the bed bug alarm pheromone contains two of the same compounds as the aggregation pheromone, but they are released in much higher quantities when the bed bugs are alarmed. At these levels, these compounds stimulate immediate, rapid movement away from the current location. Unfamiliar touches, light or high, steady levels of carbon dioxide/wind trigger the release of these compounds and subsequent movement. Alarm pheromones, like most chemical compounds for bed bugs, also are detected with the antennae. Humans actually can smell the volatile release of alarm pheromones, that oft-described “obnoxious sweetness” or “buggy” odor that is sometimes evident with heavy infestations. The alarm odor is perhaps most apparent when several bugs are confined in a small container and gently shaken.
Tracks of individual bed bugs in a laboratory test arena. Bed bugs cover a lot of ground at night even when not stimulated by a host (top). Note how they tend to follow the edges of the test arena. Movement is more directed when a heat source warmed to human body temperature is provided (below). (Haynes et al. 2008, PestWorld)
The research regarding movement of unfed bed bugs needs more study. We know that bed bugs move more frequently when they have not fed within a week when compared to bugs that recently fed. However, bed bugs held for five weeks without food moved significantly less than recently fed bugs. This may be a way for a bed bug to conserve energy stores in times when the host is temporarily absent (Romero et al. 2010). We still need to determine whether longer periods without food (such as when an apartment becomes vacant) lead to dispersal away from home base, as it appears to in the bat bug. Complaints involving bat bugs in dwellings often are associated with host dispersal or death.
An important question in respect to management is “How likely is a bed bug to move from one apartment to another and if they move, how far can they go?” Previously, there was a debate focused on whether adult females disperse more than adult males, and it was suggested that females “run from males” in the field because of the damage resulting from excessive traumatic matings. Some laboratory studies seemed to contradict this hypothesis. A recent discovery (Cooper et al. 2015) that more marked females than males were more likely to be found in areas far removed from the place where they were marked is likely to renew the debate. The additional observation that all instars of bed bugs are more mobile than was once postulated may also change the way that we think about dispersal. Obviously it remains critical to know if mated females are in fact more likely to disperse (since they could start a new population), thus more work should be aimed at supporting or refuting this claim.
SILVER BULLET BED BUG TRAP? When an insect relies heavily on communication using pheromones (such as many moth species) it may be possible to trick the insect into honing in on a trap baited with synthetic pheromone blends. Recently, the elusive contact and volatile aggregation pheromone used by bed bugs was deciphered (Gries et al. 2015). This led to high hopes that a synthetic lure could be produced that would effectively detect the presence of infestations in their initial stages. While the recent findings are encouraging, there may be significant hurdles to the utility of such an approach. It is becoming increasingly evident that bed bugs do not rely on pheromones in the same way as many other pest insects that hone in on pheromone sources from great distances. Potent long-range pheromones used by the industry to successfully monitor stored product pests may not work for bed bugs, because it is likely that communication is close range. In fact, one of the main compounds in the aggregation pheromone, histamine, requires direct touch from the bed bug for arrestment and may be detected via taste, not smell.
Furthermore, sex attractant pheromones that have the most impressive value in insect detection for pests such as the Indianmeal moth are not (as far as we can tell) part of the bed bug’s repertoire. Traps baited with synthetic compounds will need to compete with former and existing aggregations of live bed bugs whose interactions are being reinforced by tactile contact. While there’s hope for improved detection using pheromone traps, the industry should probably temper its expectations that the technology will be a panacea in the continuing effort to detect low-level infestations.
Various traps already have been marketed for bed bugs utilizing heat, CO2 and other host odors. However, when bed bugs recently have fed, responses to host cues such as carbon dioxide emission diminish. Thus, at any given time, these traps would not be attractive to the portion of the bed bug population that has recently fed to satiation. To reliably detect bed bugs at low levels, traps would presumably need to be placed in multiple locations within the dwelling, translating to higher cost and conspicuousness. We also know that the concentration of carbon dioxide changes rapidly from the point of exit (nose, mouth), to alongside the skin, to the area surrounding a host. We have not yet honed in on the most attractive concentration for bed bug movement, or determined whether carbon dioxide would perform better released in waves/pulses rather than steady streams.
INTRODUCTION OR INFESTATION? We often hear reports of a school, office, library or clinic that shut down over the presence of one to two bed bugs. The concern often stems from a presumption that one bug can turn into several and that people are likely to transport them home. A key question in respect to whether one bug will turn into several is this: Will it find a host, a mate and an aggregation offering the communal benefits noted previously? In some cases, especially when there are a few widely scattered bugs, it can be as hard for a bug to find us as it is for us to find them. Finding a mate will be no sure bet either, especially if only one bug was introduced, or two bugs of the same sex. The biggest risk of infestation occurs when a fed and mated adult female is introduced, because she has the potential to lay eggs.
However, this still does not ensure that she or her offspring will be able to find a suitable host, especially in settings where there is no sleeping person. All in all, it is probably safe to say that introductions of small numbers of bed bugs into schools, offices, libraries, retail stores and other non-bed environments are unlikely to turn into large infestations as is more common in residences. A bed bug spotted in such places necessitates action — but seldom closure/cessation of operations. While it’s easy to overreact in these situations, resources are better spent educating workers and following established protocols.
WRAP-UP. Understanding insect behavior has long helped the industry battle cockroaches, termites, ants and other foes. Learning to “think” more like a bed bug should yield similar benefits. Although eradicating infestations is the end-goal, there are other benefits to understanding their cryptic ways. Thinking like a bed bug makes us better inspectors and enhances our ability to predict their movements within buildings. It also enables more tactical “strikes” with insecticides and other treatments. Understanding bed bug behavior empowers the industry to communicate more effectively with the public on topics ranging from pretreatment preparation to prevention. If the strategy of “knowing thy enemy” worked for Sun Tzu, then maybe we can put it to work for us, too.

The alarm pheromones of bed bugs have other interesting functions as well. Juvenile bed bugs release alarm pheromones for their own protection against other bugs — specifically, misdirected mating attempts by adult males. A unique pheromone blend (consisting of four compounds) is released by young bed bugs when sexual interest from adult males is directed their way. Newly fed 5th instar nymphs closely resemble adult females in size and shape, making them a target for mating attempts from “overzealous” males. These traumatic mating attempts are costly for wounded nymphs and a waste of time for males, since they will produce no offspring (Harraca et al. 2010). Adult males also release alarm pheromones to deter homosexual mating attempts from other male bed bugs (Ryne 2009). Clearly, there are intriguing and important social interactions between bed bugs. Some may even have future implications for management.
Don’t get fixated on Bed Bugs just because you have a few bites.
It very well could be another insect or some type of reaction.
We get a lot of calls from customers with bites of some type. In many cases it is Mosquitoes, Chiggers, Sand Fleas, Seed Ticks or some other outside type insect.
I did an inspection for a man the other day that was convinced he had bed bugs. He was a Tennis Instructor and wore shorts all day.
When I saw his legs he had at least 50 bitemarks. Before we brought the K9 in, I inspected his beds and couches and found zero evidence. I knew before we brought the dog in he did not have bed bugs. For him to have that many bites he would have seen them long before now. And there would be visual evidence with that many bugs. One or two bugs did not make all of those bites. I asked him if he had been in any wooded areas. He said that he had not.
We inspected and the K9 did not have any responses or interest in any of his belongings. I told him I did not know what made the bites but it was not bed bugs. He called me the next day and told me he figured it out and I was right. He gives Tennis lessons and his students hit a lot of balls over the fence. He said he forgot about going in the woods with a bucket to retrieve balls. He said he went again today and got smoked by chiggers.
Another common error is misdiagnosing Carpet Beetles for Bed Bugs. There are many unneccessary treatments done in this area.
Below is a Carpet Beetle that a client was told by another company was bed bugs. The treatment estimate was $1800.

They don’t really look alike to me. This is a Bed Bug.
What Does Look Like Bed Bugs ?
Bat Bugs !!!!
When there are Bats Present in a Structure or If there has been Bat Exclusion work done it is common for a homeowner to find bat bugs roaming around. They look very much like bed bugs because bed bugs originated from Bat Bugs. I actually can not visually verify this out in the field without magnification. There are some slight differences however these can easily be misdiagnosed by even professionals in some situations.
Bat Bug VS. Bed Bug
If you need an inspection and/or treatment we suggest you look into Thermal Remediation Heat Treatment. This is the most effective and less intrusive treatment method. It is more of a process than a treatment. The Process generally takes about 5-6 hours.
