Identifying Swine Lice, Ticks, and Fleas
LICE
Swine Lice or Hog Lice are relatively large external blood sucking parasites.
A lice infestation causes itchy discomfort for the pigs. Infected pigs will rub against their surroundings trying to relieve the itch. Left untreated they will rub their hair off and create sores. Lice are vectors for disease such as swine pox.
Lice can be treated and prevented with ivomec, brand name Ivermectin. This is the same medication, at the same dose, that is used to treat and prevent mites. See dosage here. Pigs get lice from other pigs. Swine lice are species specific and cannot live on any other animals or humans.
Lice are identified by their size, body shape, movement, and the sticky eggs left in the pig’s hairs. They are the largest blood sucking louse found on domestic animals, much larger than the lice found in human hair.

TICKS
Ticks are soft bodied blood sucking arachnids. They are found in all environments outside, feasting on mammals, birds, and humans.
Ticks should be removed promptly if found attached to your pig. Prevention is through environmental management. Make your yard unappealing to ticks, and/or use tick repellent products or natural homemade recipes to keep ticks off your pigs. Read the info here.
