• Pediculosis is an infestation of lice

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
  • Sucking lice are more susceptible to systemic insecticide treatment than chewing 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
