A fogger is any device that creates a fog, typically containing an insecticide for killing insects and other arthropods. Foggers are often used by consumers as a low cost alternative to lớn professional pest control services. The number of foggers needed for pest control depends on the size of the space to lớn be treated, as stated for safety reasons on the instructions supplied with the devices. The fog may contain flammable gases, leading to lớn a danger of explosion if a fogger is used in a building with a pilot light or other naked flame.

Total release foggers (TRFs) (also called "bug bombs") are used to lớn kill cockroaches, fleas, and flying insects by filling an area with insecticide. Most foggers contain pyrethroid, pyrethrin, or both as active ingredients. Pyrethroids are a class of synthetic insecticides that are chemically similar to lớn natural pyrethrins and have low potential for systemic toxicity in mammals. Pyrethrins are insecticides derived from chrysanthemum flowers (pyrethrum). Piperonyl butoxide and n-octyl bicycloheptene dicarboximide often are added to lớn pyrethrin products to lớn inhibit insects' microsomal enzymes that detoxify pyrethrins. To distribute their insecticide, foggers also contain aerosol propellants.

Hazards to lớn humans
During 2001-2006, a total of 466 fogger-related illnesses or injuries were identified in the United States by the SENSOR-Pesticides program. These illnesses or injuries often resulted from inability or failure to lớn vacate before the fogger discharged, reentry into the treated space too soon after the fogger was discharged, excessive use of foggers for the space being treated, and failure to lớn notify others nearby.
Pyrethrins have little systemic toxicity in mammals, but they have been reported to lớn induce tương tác dermatitis, conjunctivitis, and asthma. Signs and symptoms of pyrethroid toxicity include abnormal skin sensation (e.g., burning, itching, tingling, and numbness), dizziness, salivation, headache, fatigue, vomiting, diarrhea, seizure, irritability to lớn sound and touch, and other central nervous system effects.
