Australia's resource for control of worms, flies and lice in sheep,
and worms in goats

The Quick Quiz

This quick quiz tests your knowledge of sheep and goat parasites and their control. 

1. Why do ewes in late pregnancy and early lactation develop much higher worm burdens than when they are dry, or in early to mid-term pregnancy?

2. What are two tests you could use to detect liver fluke in goats?

3. In winter rainfall environments, what are the 2 major causes of scouring and dags?

4. Why is managing lice easier if just one whole of flock shearing is conducted rather than using split shearings?

WormTests—what's stopping you?

If you don’t routinely use worm egg counts, which of these are you?
  • I already know when to drench
  • I don’t know what’s involved
  • I haven’t got time
  • It takes too long to get results
  • It’s too expensive

If you don’t routinely use worm egg counts, it's time to reconsider. >> Webinar details.


State Outlooks for May 2019

Areas of the sheep country are still incredibly dry, and producers are off-loading stock. In other regions, sufficient moisture and ongoing mild temperatures, morning dews, and heavy grazing of the short green pick are prolonging the summer worm season.

Immunity to worms declines in late pregnancy and early lactation.
Slow moving streams with marshy banks provide habitat for liver fluke snails.
Shearing all the flock at the one time makes lice management much easier.

New South Wales

A WormTest 6–8 weeks pre-lambing is advised.  Daytime temperatures and moist conditions are keeping worms active. Sheep blowflies continue to be active in the warmer than usual conditions, along with some rainfall.  Producers are encouraged to conduct resistance tests on maggots.

Worm burdens are expected to rise sharply from mid-June and coincide with the start of lambing for June and July lambing mobs. Time to WormTest.

The most commonly heard misconception about barber’s pole is that “frost kills the worms” and therefore sheep can’t get infected after frosts.

Western Australia
>> full report

Prolonged dry conditions across much of the agriculture areas have limited worm pick-up, but worms will be ready to go once pasture growth commences.

Conduct a fluke test before giving the winter fluke drench. Fluke test mobs that have grazed river and creek margins, or any paddocks with permanent springs.
