Registered indications
Extinosad Pour-On is registered for the control of lice (Bovicola ovis) in sheep, both off-shears and with long wool, including strains that are resistant to synthetic pyrethroid (SP) compounds.
How Extinosad works
Extinosad contains the active ingredient, spinosad, which is 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 a number of 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.3
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 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.(1) 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.(2)
Ideal for long wool
Extinosad Pour-On is the most effective pour-on treatment available to kill lice in sheep with long wool. (2) 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!(2)

Application guidelines
Apply using the special manual applicator or a powered applicator fitted with a modified t-bar nozzle. Halve the dose volume and apply as two bands approximately 5 cm from the backline on each side of the animal. Apply each band evenly from the poll to the base of the tail. Confine treated sheep in the yards for a short time to improve the spread of Extinosad Pour-On around the body via rubbing and/or physical contact with other sheep.
Always read the label instructions before use
Getting the best results
- Treat all sheep on the property at the same time.
- Muster each paddock thoroughly to ensure all sheep are treated.
- Check boundary fences to ensure treated sheep are contained and to prevent untreated or lice-infested sheep from joining treated mobs.
- Do not mix treated sheep with untreated sheep, infested sheep or those of unknown lice status.
- Do not use on sheep with lumpy wool.
- Sheep that require treatment with a long wool lousicide should be re-treated after shearing.
- Moderate rainfall occurring after treatment will not adversely affect lice control provided by Extinosad Pour-On.
