Applying Avenge in long wool (6 weeks to 8 months after shearing) provides protection against flystrike for up to 14 weeks, so you get all the convenience of one product for multiple jobs. Avenge is the only fly control product containing imidacloprid, a neonicotinoid insecticide. No resistance has been reported to imidacloprid.

Avenge is the only knockdown pour-on product with a four week residual period* against lice and up to 10 weeks protection against flystrike off shears.

Avenge controls susceptible body lice (Bovicola ovis) when applied up to 7 days off shears and on unshorn lambs up to 2 months of age. Avenge has a four week residual activity for lice (when applied within 24 hours off-shears), offering protection against re-infestation for complete peace of mind. It will continue to kill any lice that hatch from eggs following treatment and protect sheep from reinfestation from stray sheep or other lousy sheep for up to four weeks. Avenge also offers up to 10 weeks protection against fly strike off shears.
