Like all pour-on lice products, treating straight after shearing is ideal. 

Flystrike is always a problem of sheep over Summer especially with the Aussie green blowfly that lays live maggots.  Sheep are prone to attack 3-4 weeks after shearing and require a product that is effective and long lasting.  Products with the actives cyromazine (Cyrazin) and ciylanil (CLiK) have no known resistance.

Another very safe prodcut spinosad (Extinosad) is great at killing maggots and is deadly on lice.
