Where It Comes From
Home aerosol sprays/foggers, some pet sprays/shampoos, and mosquito control products [1][3].
How You Are Exposed
Breathing indoor air during/after spraying, touching treated surfaces or dust, hand-to-mouth contact (especially in children), and occupational mixing or application [1][2].
Why It Matters
Short-term effects include eye/skin irritation, coughing/wheezing, dizziness, and nausea; large exposures can cause tremors or seizures. Very toxic to aquatic life—keep out of drains and waterways [1][2].
Who Is at Risk
Pest control workers, people with asthma or breathing problems, young children, and pets (especially cats) [1][2].
How to Lower Your Exposure
Use integrated pest management (seal entry points, clean food debris). Choose baits/traps first. If spraying, follow the label, ventilate well, leave the area, and keep kids/pets out until surfaces are dry; wash hands and clean high-touch areas afterward. Applicators should use recommended protective gear [1][2].
