Critical comments

1. When used for long wool jetting, sheep should be re-treated with an effective off-shears or short wool product after shearing.
2. Reduced effectiveness is likely if used on sheep with lumpy wool.

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 shoud 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 treated with an off-shears or short wool product at the next shearing.
