Hi just tried this product,got instructions from company below.
The Multi-Wormer is designed to be used as a continuous dewormer, fed every day. Of course, most people don't want the added cost and hassle of feeding forever.
You'll get great results with this line of treatment.
Feed one scoop of the Multi-Wormer per pound of feed daily for 2-3 weeks. 2-3 months later do a purge of daily treatment for a week-10 days. This will eliminate any worms that the birds have been infected with during the non-treatment period.
I hope this helps, let me know if you need anything else.
