Mosquito Halt Repellent Spray is a topical, ready-to-use formula designed for use on horses, ponies, and foals. The blend pairs permethrin and prallethrin with piperonyl butoxide and additional repellent compounds to deliver quick knockdown along with lasting repellency against mosquitoes and several fly species, plus gnats, mites, chiggers, and lice. The spray also carries aloe and lanolin to help condition the coat and skin during application. It comes in a 32 oz trigger-spray bottle that requires no mixing or dilution before use. Application is done by covering the coat while brushing against the grain, or by wiping on with a clean cloth or sponge, avoiding the eyes, mouth, and other sensitive areas. The product is intended for use only in well-ventilated areas and the bottle should be held upright while spraying.
