Good Morning and welcome to Just answer. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
Yes, the treatment for lice is the same as the human treatment and bathing with this will remove most of these. Bath him every week for 3 weeks. the purchase Ivomec at the farm supply or online and give an injection which will be 1 cc per 110 pounds. Since your little one is so small, the dose will probably be 0.1 -0.3 cc. You can repeat this every 6 months.
