Where It Comes From
Community mosquito spraying (ULV fogging) and some indoor/outdoor insect sprays; products are regulated by EPA [2][3].
How You Are Exposed
Breathing air during/after spraying, skin contact with treated surfaces, or touching residues; typical dietary exposure is low [1][2].
Why It Matters
Affects nerves (paresthesia, irritation) [1]; EPA does not consider it likely to cause cancer; it is highly toxic to fish and bees [2].
Who Is at Risk
Pesticide applicators and people nearby during spraying; young children; people with asthma or chemical sensitivities; pregnant people may wish to minimize exposure as a precaution [1][2][3].
How to Lower Your Exposure
During community spraying, stay indoors, close windows, and bring items inside; after, ventilate and wait until sprays dry. At home, follow labels, keep kids/pets off treated areas until dry, and use integrated pest management [2][3].
