Chicken Body Louse

The most damaging louse of domestic poultry, feeding on feathers, skin, and blood. Heavy infestations cause feather loss, reduced egg production, and anemia.

💡

Did You Know?

This louse is unusual among bird lice because it actively feeds on blood by gnawing through pin feathers, not just on feather material.

Hog Louse

The largest louse found on domestic animals, exclusively parasitizing pigs. It feeds on blood and is most commonly found behind the ears and in skin folds.

💡

Did You Know?

At up to 6 mm long, the hog louse is the largest sucking louse known, easily visible to the naked eye on infested pigs.
