ARPON® ectoparasiticide is a solution for spraying, indicated for the control of external parasitosis caused by flies and lice in cattle, and flies in horses, except those intended for human consumption. Its active ingredient, cypermethrin, is a contact ectoparasiticide from the group of type II pyrethroids, characterized by containing an alpha-cyano group in its molecule.

Type II pyrethroids primarily affect sodium channels in the nerve membrane and cause a prolonged increase in sodium membrane permeability during excitation. They maintain persistent modification of sodium channels, depolarize the membrane, and block action potentials without causing presynaptic repetitive activity.

It is active against:

Flies: Haematobia irritans, Musca automnalis, and Hydrotaea irritans.

Lice: Lignonatus spp. and Haematopinus spp.

Applications:

External parasitosis caused by flies and lice in cattle, and flies in horses, except those intended for human consumption.

Mode of use

• Fly control: Spray at the beginning of the fly season and repeat every month. In case of excessive abundance of horn flies and face flies, spray every 15 days.
• Lice control: Spray the entire body of the animal when lice are observed. Repeat as necessary, with a minimum interval of 14 days. For fly and lice control, administer the solution of 0.1g cypermethrin/100ml water (0.1%) (equivalent to 1ml of ARPON®/100ml water), applying:
• Adult cattle and horses: 500ml.
• Young cattle: 250ml.
• Calves and foals: 125ml.
