Dairy Bomb 55Z is a ready-to-use aerosol spray built around a pyrethrins and piperonyl butoxide formula for fast insect knockdown. The pressurized can is designed for direct application to cattle, horses, swine and poultry as well as space spraying in barns, dairies, milk houses, stables and other animal quarters. It leaves minimal oily residue and uses a non-flammable, level 1 aerosol propellant system that avoids ozone-depleting chemicals. The spray targets a wide range of flying and crawling pests including flies, mosquitoes, gnats, roaches and spiders in and around livestock facilities. Users shake the can before use and follow label directions on distance, duration of spray and ventilation for each intended setting. Because the same can serves both on-animal and premises use, application rates and hold times differ by location and should be confirmed on the product label before each use.
