Sheep lice


Sheep lice cost NSW sheep producers about $123 million per year in treatment costs and lost production.

Eradication of lice would save this money, and there would be the added benefit of producing wool with lower insecticide residues.

Sheep are prone to infestation by body lice, face lice and foot lice but only the body louse presents a serious problem.
