How long does a bed bug treatment last?

Bed bug extermination can last forever as long as the treatment killed all the bed bugs (and their eggs) and if new bed bugs are not transported into the location. Factors that can affect the outcome are how severe the infestation is and whether all bed bug sources were properly identified and treated. When working with a pest control professional, the EPA recommends you check and call references; ask if they offer both chemical and non-chemical treatment options, if they recommend both encasements and interceptors, and if they offer two or more service visits and follow-up. Bed bugs are tiny (adults are roughly the size of an apple seed) and can hide anywhere a credit card can slide into. They squeeze into cracks in walls, behind electrical outlet sockets, in bedding, and in other dark places. Learn how to prepare your home for a bed bug treatment for the best outcomes. Michigan State University shares some examples of possible reasons that a bed bug extermination is not 100 percent effective:

  • Not all sources (aka hiding places) of the bed bugs were identified during initial inspection.
  • Not all sources of bed bugs were treated.
  • The insecticides used were not effective or, in the case of heat treatment, there was insufficient contact time.
  • Infested items such as bedding or other materials were reintroduced into a cleaned area.
