Bed Bugs vs. Bug Bombs: The Bugs Win

If you’ve ever had bed bugs, you’ve probably tried everything to get rid of them, including setting off a bug bomb. But a new study shows that these popular consumer products are no match for the blood-sucking pests.

Researchers from the Department of Entomology at Ohio State University looked at three brands of bug bombs, also known as foggers, from a nationwide retailer and tested their effectiveness on five different bed bug populations in the lab.

What they found was what pest-control experts had long thought. “There has always been this perception and feedback from the pest-management industry that over-the-counter foggers are not effective against bed bugs and might make matters worse,” said lead author Susan Jones, an urban entomologist with the Ohio Agricultural Research and Development Center, in a statement. “But up until now there has been no published data regarding the efficacy of foggers against bed bugs.”

Jones and her colleague Joshua Bryant found that Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger had little to no effect on the bed bugs. (Only Hotshot Bedbug is specifically labeled for use against bed bugs.) “All three total-release foggers claim ‘kills on contact’ yet all field-collected bed bugs were unaffected upon re-entry,” the authors write. Even five to seven days after contact, the bed bugs remained unharmed.

Since bed bugs spend their time hidden under sheets, mattresses and deep inside carpets, the authors say it is likely they are protected from the foggers’ mist. “These foggers don’t penetrate in cracks and crevices where most bed bugs are hiding, so most of them will survive,” said Jones in the statement.

Even when the bugs do come into contact with the insecticides, their varying levels of resistance to the insecticide and the foggers’ poor toxicity leave the crawlers unscathed. “If you use these products, you will not get the infestation under control, you will waste your money, and you will delay effective treatment of your infestation,” said Jones.

The majority of foggers contain insecticides pyrethrin and pyrethroid. The authors note that most field-collected bed bugs are now resistant to pyrethroids, fueled largely by the unnecessary introduction of insecticides into the environment by humans, according to the researchers. Such resistance has helped drive the resurgence of bed bugs in recent years.

To figure out if your home is infested with bed bugs, here are the (unpleasant) signs to look for, according to the Centers for Disease Control and Prevention:

  • The bed bugs’ exoskeletons after molting
  • Bed bugs in the folds of mattresses and sheets
  • Blood-filled fecal material, which shows up as rusty-colored blood spots, that bed bugs excrete on the mattress or nearby furniture
  • A sweet, musty odor

“The public is ill-served when products do not perform in accordance with labeling and use directions claims,” Jones wrote in the study, published in the Journal of Economic Entomology.

They do not like heat and you have to steam the area with a steamer that gets to 180 degrees to kill the active bugs, eggs and larvae. Plus you have to spray the area. The bombs will only kill the bugs that are on the surface of things like your dresser, bed, or carpet, but will not kill anything that is in your bed, or carpet or the baseboards. That you have to use a contact spray on after you steam the areas, or remove the baseboards completely to treat behind them. Plus, if you move one article between rooms, you will infect your whole house. So you have to be careful not to move anything from room to room. It is a horrible infestation and costly to get rid of.

bed bugs have been spreading like wildfire in my family and at my friend's houses.I have tried several different things including an exterminator which was very costly.

bed bug bombs and spray from Walmart in the purple can a little expensive but well worth it they are the hot shot foggers and the regular spray.if anyone tells you that foggers aren't good for bed bugs they're wrong they have helped us tremendously.also put your clothes in the dryer for an hour and a half to where they are so hot it burns to take them out bed bugs cannot stand heat.

also, they do not drowned tried it they can live in water crazy I know but I wanted to know how to fix the problem. Hope I could help everyone this problem is horrible. Do not let anyone in your hoise with back packs or anything really.

Good luck.
