What can one say—dry, dry dry. Few if any worms anywhere.
The only note of caution: on most properties, the only worms on the place will be in the sheep. Good oh! you may think—I'll drench now and get the lot of the so and so's.
Not so, it is unlikely you will kill ALL the worms—meaning those left will be the ones resistant to the drench you used. Come the rain, then the only worms around will be resistant ones. Plenty of properties in western Queensland have drench resistant worms on them. The only saviour is the climate being hostile to worms most of the time.
Test, always test, before drenching.
