We are having bad trouble with flies this year (we are located in southwest Virginia). Normally we really don't use much fly protection besides fly tags but this year the flies are really bad so I bought a couple backrubbers and the guy at the feed store told me to mix the insecticide with diesel fuel or mineral oil. Im just not sure about the cows having diesel fuel all over them and mineral oil is like $15 a gallon. I was wondering if I could use used frying oil with the insecticide I can get gallons of it for free if it would work? If not is diesel fuel safe to use on them?
