got Horse Lice products and info?

Just took in a young horse and notice he is infested with lice. Bathed him and killed most. Wondering if it is possible to erradicate them completely, and when can he be near other horses again? What products do you sell that I can use for him.  Thanks!!

Our Bug Check spray will kill lice. it is not 100% natural but is as natural as possible and still kill. also the key to lice is the immune system. I would really suggest our Health Check and Bug Check as supplements to help from the inside out immune system wise. Also look at our feeding program. (
