Fipronil is an insecticide and acaricide belonging to th e phenylpyrazole family. Fipronil and its metabolite fipronil sulfone act at ligand-gated chlori de channels, in particular those gated by the neurotransmitter gamma-aminobutyric acid (GABA) as well as desensitising (D) and non-desensitising (N) channels gated by glutamate (Glu, unique invert ebrate ligand-gated chloride channels), thereby blocking pre- and post-synaptic transfer of chlori de ions across cell membranes. This results in uncontrolled activity of the central nervous system and death of insects or acari.

(S)-Methoprene is an insect growth regulator (IGR) of the class of compounds known as juvenile hormone analogues that inhibit the development of immature stages of insects. This compound mimics the action of juvenile hormone and causes impaired development and death of the developing stages of fleas. The on-animal ovicidal activity of (S)-methoprene results from either direct penetration of the eggshell of newly laid eggs or from absorption thr ough the cuticle of the adult fleas. (S)-methoprene is also effective in preventing flea larvae and pupae fro m developing, which prevents contamination of the environment of the treated animal s with the immature stages of fleas.

Amitraz is a formamidine acaricide that acts as an a gonist on octopamine receptors causing an over- stimulation of octopaminergic synapses in acari, resulting in tremors and convulsions. Moreover, at sublethal concentrations these compounds have the ability to cause anorexia in acari and suppress their reproduction. Specific tick detachment properties d escribed as an expellant action causing ticks to withdraw their mouthparts rapidly and fall off th e host animal have been reported for amitraz.

The combination of amitraz and fipronil acts on multiple sites of the nervous systems of ticks. A low dose of amitraz together with fipronil has shown sy nergistic efficacy against ticks resulting in an increased speed of kill (starting at 2 hours and great er than 90% at 24 hours) and a longer duration of activity when compared to the activ e substances administered alone.
