Emulsifiable concentrated insecticide and acaricide. Its active ingredient, Cypermethrin, is a contact insecticide belonging to the type II pyrethroid group, which are characterized by containing an alpha – cyano group in its molecule. The type II pyrethroids principally affect the Sodium channels in the nerve membrane, and cause a prolonged duration of the transitory increase in the permeability of the membrane to Na during nerve stimulation. This action causes a quick paralysis to the insect. Cypermethrin has a quick and persistent effect.

ARPON® is effective against:

Bovine and horses: flies (Haematobia irritans, Musca automnalis, Hydrotaea irritans).
