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.
