How Extinosad Pour-On for Sheep Works:

Extinosad contains the active ingredient, spinosad, derived from the naturally-occurring soil bacteria, Saccharopolyspora spinosa. Once absorbed or ingested by target insects, spinosad causes prolonged involuntary muscle contractions and tremors, resulting in neuromuscular fatigue, paralysis and death. Spinosad has a high level of activity against many insect species, including the sheep body louse (Bovicola ovis). Its unique mode of action controls lice strains that are resistant to insect growth regulator (IGR) and synthetic pyrethroid (SP) compounds.

Despite its deadly activity against lice, Extinosad Pour-On poses remarkably little risk to humans, livestock or the environment when used in accordance with the label directions. It can be applied safely to all classes of sheep, including lambs.

Ideal for Off Shears:

Extinosad Pour-On for sheep is ideal for off-shears lice control. Its unique mode of action kills lice within hours and provides a much-needed alternative to insect growth regulator (IGR) compounds, to which resistance has been identified. In four large-scale trials involving Merino wethers, ewes and rams, lice were undetectable in sheep five months after treatment with Extinosad Pour-On off-shears.

Ideal for Long Wool:

Extinosad Pour-On for Sheep is the most effective pour-on treatment available to kill lice in sheep with long wool.  It kills lice within hours, including those strains resistant to synthetic pyrethroid (SP) compounds (e.g. Vanquish†) and has no wool or meat withholding periods. Extinosad Pour-On delivers excellent control of lice in sheep with long wool. Seven Australian field trials found Extinosad Pour-On reduced lice numbers in long wool sheep by an average of 97.3% two months after treatment.
