Fipronil Belongs to the family of phenylpyrazole. It acts by interaction with complexes formed between the chloride channels and their ligands, especially the neurotransmitter GABA (gamma-amino butyric acid), thus blocking the transfer of chloride ions across cell membranes to levels pre and post synaptic. It thus causes uncontrolled activity on the central nervous system of insects and mites and causes their death. Fipronil kills fleas within 24 hours, ticks (Dermacentor variabilis, Rhipicephalus sanguineus, Ixodes scapularis, Ixodes ricinus, Haemaphysalis longicornis, Haemaphysalis flava and Haemaphysaliscampanulata) and lice within 48 hours after application of the product.
