Its widespread use makes its specific effects the subject of considerable attention. īecause of its effectiveness on various pests, fipronil is used as the active ingredient in flea control products for pets and home roach traps as well as field pest control for corn, golf courses, and commercial turf. As of 2017, there did not appear to be significant resistance among fleas to fipronil. Fipronil's specificity towards insects is believed to be due to its greater binding affinity to the GABA A receptors of insects, than to those of mammals, and to its action on GluCl channels, which do not exist in mammals. This causes hyperexcitation of contaminated insects' nerves and muscles. Fipronil disrupts the insect central nervous system by blocking the ligand-gated ion channel of the GABA A receptor and glutamate-gated chloride (GluCl) channels. ![]() Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole chemical family.
