"DO YOU KNOW IF YOUR DRENCH WAS EFFECTIVE?"

DRENCH CHECK

A quick drench check is a simple cost effective tool for keeping track of how each drench group is performing. A drench check consists of two worm egg counts. One worm egg count is performed before the drench and another 10-14 days post drenching. This is to check if the drench has reduced the worm egg count.

A drench is considered effective when worm egg counts are reduced by 95% or more. Worm typing (larval culture and differentiation) should be carried out, if the drench is not effective, to determine the species of worms that are resistant to the drench you have just administered.
