Control
- Few insecticides will kill lice eggs on the animal
- Two treatments are needed to kill nymphs emerging from eggs at the time of the initial treatment and those that will emerge 2-3 weeks later
- At two week intervals
- Or a product with a two week residual activity can be used
Anopleura lice are more susceptible to systemic insecticide treatment than mallophaga lice
- Resistance to insecticides may become a problem so alternating the chemicals used and avoiding pour on treatments (which have a greater risk of resistance developing) should be considered
