Recommendations for Lice Control

  • It is recommended that a thorough muster be conducted so that no untreated sheep remain.
  • Boundary fences should be checked to ensure animals are contained and stray sheep are excluded.
  • Treated sheep must be kept separate from lice infested sheep or sheep of unknown lice status.
  • For effective control, every sheep on the property should be treated at the same time.
  • Avoid split shearing.
  • Avoid treating ewes within six weeks of the commencement of lambing.
  • Sheep that require a long wool treatment should be retreated with an off-shears or short wool product at the next shearing.
