Heat is non-toxic, and can kill all bed bug life stages including bed bug eggs. However, heat treatment of any kind (except your home clothes dryer) is still relatively expensive and has no residual (long lasting) activity. The lack of residual activity means that bed bugs can re-infest again the day after treatment.

Bed bugs may have lived through the treatment or were not quite dead (“walking dead”). It is possible that during the application the bugs were not exposed to enough chemical or heat, causing the customer to find them 7 to 10 days after the treatment was completed.

Pyrethroids are synthetic chemical insecticides that act like pyrethrins. Both compounds are lethal to bed bugs and can flush bed bugs out of their hiding places and kill them.

It typically takes anywhere from 2-4 treatment sessions over a period of 3-6 weeks to completely eliminate bed bugs, depending on the level of infestation and the size of the house. However, each situation is unique.
