Can I use Hi-Yield 38-Plus Insect Control 38% Permethrin in a barn and chicken coop to get rid of flies, fleas, and other insect pests?

Will it harm cows and chickens?


Hi-Yield 38 Plus Insect Control 38% Permethrin cannot be used indoors in a barn or chicken coop; it can be used outdoors around barns. You could use Onslaught Insecticide around and inside barns and chicken coops to treat where flies rest and to treat the ground for fleas. We also recommend adding NyGuard IGR insect growth regulator for flea control. You can apply these products while the animals are not present, and they can return once the application is dry. Keep in mind that for the best fly control, you will likely need to use a combination of insecticides, bait, traps, and on-animal treatments for biting flies. We also recommend that you inspect for rodent issues in the case of fleas since rats and mice can bring parasites into a barn.
