Sheep producers face the unenviable odds of a 50% chance of introducing lice to their flock every time they buy new sheep – a major reason the pest costs the sheep industry more than $150 million a year in reduced income and management costs.

Unfortunately the prevalence of lice in Australian sheep flocks has a long-term base average of about 20%, with the proportion of flocks infested much higher in some areas.

But the good news is that sheep and wool producers can successfully reduce their risk by carrying out farm biosecurity planning as part of their monitoring and treatment regime.
