Sprays and dusts for lice
Lice are often found on jowls, legs, inside the ears, and on the underside of the body. These areas need to be covered thoroughly. A second treatment is usually needed to break the life cycle of lice, the label will usually give a minimum retreatment interval. Bedding treatments may be needed in severe infestations. See the label for instructions.

Effective control of mange mites and lice on swine requires sound management practices as well as proper selection and application of insecticides. Mites and lice are spread by direct contact among animals within the herd. New animals added to the herd should be treated before coming in contact with other animals. Pens should be thoroughly cleaned and disinfected before introducing uninfested animals. Since mange can spread rapidly among new-born pigs, it is a good practice to treat boars before the breeding season and sows before farrowing. If an outbreak of lice or mange does occur in a herd, the entire herd should be treated.
The materials listed in the tables below are recommended for control of mange mites and lice. Products listed for mange mites will also effectively control lice. If lice are the only problem, additional insecticides may be used (see Lice on Animals table above). Sprays should be applied with equipment large enough to thoroughly wet the animals. A second treatment, 2 weeks after the first, may be needed to control newly emerged lice or mites. Sprays should be applied on a warm, sunny day so animals will dry rapidly. Dusts are generally less effective than sprays but can be used if only a few animals need treatment. Pour-ons and bedding/pen treatments are effective against lice and are recommended in cold weather when spraying is prevented. Always be sure to read and follow label directions, including pre-slaughter intervals. Do not contaminate feed or water. Follow label precautions against simultaneous use of these products with medications for internal parasite control.
