Research supports the view that total-release foggers lack the ability to penetrate into typical harborages used by many household insects, therefore rendering these products ineffective as control agents.
Field-collected bed bugs typically were not affected by direct exposure for 2 hours to the fog, hence resistance appears to play a role in the foggers failure to kill bed bugs.
The potential behavioral effect of foggers on bed bugs needs to be evaluated as it may increase the difficulties associated with bed bug control. In fact, an increase of movement and or relocation was detected.
