Methoprene

Methoprene is an insect growth regulator that mimics juvenile hormone in insects, preventing larvae from developing into reproducing adults. It is used in food storage areas, processing plants, and mushroom cultivation to control beetles, moths, and flies without the broad toxicity of conventional insecticides. Because it targets insect development rather than the nervous system, it is considered relatively safe for mammals, and the US EPA classifies it as not acutely toxic. Residue limits and good manufacturing practice govern its use around stored commodities, and pest-management professionals apply it as part of integrated programs that reduce reliance on broad-spectrum sprays in food facilities.
