I use Fly Predators. You can get them online through Fly Predators.com They are great we have used them for three months now and have literally no flies. It is a little flying bug theat you scater around and it kills all kinds of flies. We have goats and a horse and have no flies I sprinkle them near the coop and it takes care of flies near the coop. Also you do not have to order Orange Guard through the internet. Ace hardware sells it If your local hardware store doesn't carry it siimply go online to Orange Guard .com and it gives you a site to have your Ace hardware carry it. Why pay for shipping when you don't have to. Ii use it everywhere its great inside and out and I love the orange smell it leave. Micki
