Research out of Ohio State finds foggers have little impact on modern-day bed bugs due to the brief exposure times, their relatively low concentrations of pyrethrins and/or pyrethroids, and their lack of residual activity. And, the insecticide mist from such foggers had no adverse effects on any bed bugs that were in harborages — their typical location. Bed bug foggers don’t work?
For decades, “bug bombs” or “foggers” have been sold as over-the-counter (OTC) products for consumer use against many common household insects. Foggers act by broadcasting an insecticide mist by way of an aerosol propellant. These products typically are easy to use and require little effort, and they are commonly used by consumers as a low-cost alternative or supplement to professional pest control services. The U.S. Environmental Protection Agency (EPA) recently estimated that about 50 million foggers are used annually in the United States.
The name “bug bomb” seems rather fitting given that explosions have been reported when excessive numbers of foggers have been used or when a nearby ignition source, such as a pilot light, has remained on during fogging. Such explosions are newsmakers worldwide.
