A: Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism. No milk withdrawal required. WARNING: Cattle must not be slaughtered within 13 days following last treatment. For dairy cattle, there is no milk withdrawal period. A withdrawal period has not been established for this product in pre-ruminating calves. Do not use in calves to be processed for veal.

A: Safe-Guard is safe for nursing cows. The product is not harmful to the nursing calf. However, if the calf is going to be used for veal, it should not be used. It can be used on dairy cattle., as the milk discard time is zero hours. It does not repel flies. We do not have a product on the market that repels flies. We have mineral and other products that contain Altosid, which helps control horn fly populations (not totally eradicate them) by stopping the development of adult flies in cattle manure.
