What can I do for my little lamb? She is a barbado and has a tick problem. I noticed that she was not quite so spirited today so I caught her and found little knots under her front arm pits and a couple of them had ticks attached. When we squeezed the knots pus and blood came out. I've never seen a knot this big from a tick bite but on each one I could see where the tick had been attached. I have been using liquid seven on my cow to control them, is it safe to use on this lamb? It is the same as seven dust only in a liquid form and I dilute it more than the instructions say. She will be three weeks old next Monday. None of my adult ewes have ticks, I'm guessing lanolin?
