Lewis Cattle Oilers are fully automatic, external parasite control machines that help reduce anaplasmosis, pink-eye, fly, flea, and tick infestations. They are designed to be used year around and will help with lice, mange mites, and ringworm through the winter months. We are a 54-year-old company that manufactured in Canada for 45 years, but moved to Bryan, Texas, 9 years ago. Proudly made in the USA!
