How do these products work? Bed bug foggers are supposed to work using aerosol insecticides contained in a metal can. People with bed bug problems are instructed to place one of these foggers in the room infested with bed bugs, release the aerosol manually and then leave the room for several hours. Foggers are usually marketed using terms like "affordable" "easy-to-use" and "cost-effective alternative to pest control companies". However, entomological research studies pitting bed bug foggers against real bed bugs show that these aerosol bombs have no effect whatsoever on bed bugs, as well as other insect infestations.

Why Foggers Fail to Kill Bed Begs
Over the past decade, bed bugs have evolved to resist insecticides because certain chemicals were originally used to kill them. Eventually, bed bug genetics learned how to adapt to these insecticides and passed resistant genes to offspring. Current studies examining the effectiveness of insecticides against bed bugs has revealed that nearly 90 percent of all bed bugs are no longer affected by traditional pesticide ingredients found in insect foggers and bed bug bombs.
