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


At last! Some good rain across the eastern states. Probably not enough to give any real relief to many places, but it should generate some green pick for most. A lot depends on what, if anything, comes next. No rain means rapid descent back to drought, more useful rain will probably bring flies and worms along with the feed. Start planning for both possibilities!   —Arthur Le Feuvre

A mixed bag—generally worm activity is moderate to low, but some high counts where management has been deficient. Good management has been rewarded with little need for drenching and healthy sheep. Regular worm egg counts are essential following the widespread and generally useful rain.

Monitor lambs every 2–3 weeks to avoid any crashes and loss of productivity. Every kilo of weight a lamb to market puts on is worth much more than the cost of the WEC. Watch out for fluke.

What a difference the recent rain might make! If you get any further falls, a few monitoring WECs might be a good idea in around 4–6 weeks. Proper quarantine drenching is making a difference where it is being used.

Highly variable conditions across the sheep areas mean it's hard to give a blanket view. While rain has been insufficient for most crops, there is still enough short green pick and moisture to keep worms cycling. As always, producers with recent resistance test data and WECs are streets in front of those who don't.

The big swings in rainfall continue. Things have (sort of) dried out, Xbred ewes are in excellent condition, but some Merino weaners are in trouble. Be careful using long acting drenches in these situations—it might come back and bite you.

While rain (and frosts) have come, El Niño still seems likely. Variable egg counts across the state highlight the need for WECS to make sound drenching decisions. Start preparing weaning paddocks 6 months in advance.
