Elanco Lice Management Guidelines

Good management is critical for effective lice control, particularly when using a short acting, knockdown product such as Extinosad Pour-On. Short acting, knockdown products have little to no ongoing protection period. Extinosad Pour-On does not have a registered protection period.

  1. Treat all sheep on the property at the same time.
  2. Muster each paddock thoroughly to ensure all sheep are treated. Conduct a second muster if necessary.
  3. Check ALL fences (especially boundary fences) to ensure all treated sheep are contained and to exclude untreated or lice infested sheep from joining.
  4. Do not mix treated sheep with untreated sheep, lice infested sheep or those of unknown lice status.
  5. Sheep must be cleanly shorn. Grass seeds, lumpy wool or flystrike can hinder shearing and may impede the effective spread of Extinosad Pour-On.
  6. Treat all sheep in accordance with the Extinosad Pour-On application guidelines set out on the label.
  7. Do not treat ewes within six weeks of the commencement of lambing, as live lice may infest the lambs from these ewes.
  8. Do not treat sheep when they are wet or if rain is likely. However, moderate rainfall (20mm in 20 minutes) following treatment does not adversely affect the effectiveness of Extinosad Pour-On.

Chemical Rotation Guidelines

  1. It is not recommended to apply consecutive applications of any lousicide with the same mode of action.
  2. It is not recommended to apply products with the same mode of action to control lice and protect against flystrike during the same wool growing season.
  3. Rotation between products with different modes of action may prolong the effective life of all available treatments.
  4. Apply all lice treatments as part of an integrated pest management program (visit
