Alberta | Cleanup II has zero withdrawal for butcher animals We have been using for 3 years, it works fantastic. In order for that to happen, you have to do every single animal on the farm, preferably at the same time or in a couple days, Isolate newcomers for 3 or 4 days so they cannot contact treated animals after you do them until the pour-on has a chance to kill everything on the animal. I cleanup is good for a week after treatment as it is oil based, but all it takes is contact with one animal that was missed or an animal who still has live lice to infect everything again. My vet told me that the lice cannot jump but they have to have physical contact with another animal. I am not sure about that as the lice on my dog will jump around on your clothes if he happens to drop a few on you. We do our animals with ivermec in the fall and cleanup in Feb and again before they go to grass in May. | |
