Fipronil disrupts normal nerve influx transmission (e.g., passage of chloride ions) by targeting the GABA-gated chloride channel, causes excessive neural excitation, severe paralysis, and insect death. It is also considered a selective GABA antagonist because it shows a greater binding affinity to insect than to mammal GABA receptors.
