Previous studies have shown that cattle and sheep that are treated topically with Butox 7.5 (deltamethrin) on the neck or along the back are protected from biting Culicoides spp. for up to 4 weeks. During these studies, the animals were provided with adequate shelter against the rain. The efficacy o...
