Need to read label or you could be killing your horse or yourself. Not to be sprayed while in the barn. Cheap because the inert is toxic. You get what you pay for
Does not work at all....I only have a two stall barn and clean my stalls twice a day. I have an auto mist system that goes off every 2 hours for 45 seconds and there are hundreds of flies still!!! Don't waste your money on this product.
