The transference of bed bugs from one residence to another is very hard to control. In multi-unit housing management has a difficult task in trying to control the spread. Most Apartment leases have bed bug language in their contract shifting the financial responsibility over to the tenant. In subsidized housing however this can be of great expense. There is bed bug movement in units however this is usually carried on cloth or wood from one unit to another.
