Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazolechemical family. Fipronil disrupts the insect central nervous system byblocking GABA-gated chloride channels and glutamate-gated chloridechannels. This causes hyperexcitation of contaminated insects' nerves andmuscles. Fipronil's specificity towards insects is believed to be due to itsgreater affinity to the GABA receptor in insects relative to mammals and itseffect on GluCl channels, which do not exist in mammals.
