Please remember, when using permethrin or pyrethrins, this product is TOXIC to CATS. If you have a barn cat, lock her out, and your clothing should be put in the wash and you should shower so as not to spread it indoors to your cat. Other than cats, the product is AWESOME for getting rid of bugs of all kinds! I use horse spray while they are on the roost at night, I get their bums and under the wings. When I clean the coop, i spray all wood surfaces and corners just to be sure.
Edit: Permethrin is the synthetic version of pyrethrin which occurs naturally in chrysanthemum flowers. When using any insecticide around your cat, be sure to check that the product does not contain either of these!
