Use an ML as a routine quarantine drench for all sheep introduced onto the farm, regardless of their origin and drenching history. Keep the use of MLs to the minimum possible. Faecal egg count monitoring can be used to avoid giving more drenches than necessary. In drier inland areas, if egg counts are very low, a summer drench may not be needed at all. Avoid the exclusive use of MLs.
Precautions Read the label on the drench pack.
They should not be diluted or have off-label treatments added to them. As these drugs tend to concentrate in fat, they should not be used in sheep that are producing milk or milk products for human consumption. MLs break down in strong light and should be stored only in the original pack. Drench remaining in clear plastic backpacks should be returned to the drum. Do not use MLs in any manner other than indicated on the label.
