The hog louse is the largest louse species (6,4mm) commonly associated with domestic animals. It is found most frequently in the folds of skin behind the ears and between the legs. The blood-sucking activity of hog lice results in much irritation and discomfort to swine.
|Adults and eggs attached to the hog's bristles.
Eggs are glued to the bristles at the rate of three to six per female per day. The louse causes severe irritation resulting in a depressed growth rate.
Two to 3 weeks are required for eggs to hatch, and the nymphal stages persist for approximately 2 weeks.
