Opti-Force Sweat Resistant Fly Spray

Provides repellency and quick knockdown from biting and nuisance flies (horse, house, stable, face, horn and deer), gnats and mosquitoes (Culex spp.) that may transmit West Nile Virus. For use on horses and ponies.

Contains 1% cypermethrin.

Directions: Avoid contact with eyes or mucous membranes. Spray liberally for best results. Apply to face using clean cloth or sponge. Reapply every 14 days for fly control under normal conditions and for initial applications. As protection builds, reapply every 14-17 days. Reapply every 5-7 days for mosquito repellency. Reapply each time animal is washed.
