Electronic pest control is the name given to any of several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
The devices usually have the form of smoke bombs. The best known such application of smoke compositions is in riot control, for dispersion of lachrymatory agents.
