quite possibly, I knew a lot of farmers which used to dip their sheep and I was thinking of dipping them, but I never liked the idea of tons of chemicals on them and therefore on me when I handled them, so I was considering an alternative on what I had read somewhere about using essential oils instead; However I am sure this would cost way too much and you would have to dip often and I am not sure how much time i would have for that. Fly strike has be down from last year, so I suppose thats saying something in itself?
