The Honey Bee Health Coalition has an 80 page guide available for free download at
honeybeehealthcoalition.org/hivehealthbmps.
The Coalition worked with Dr. Dewey Caron to develop a guide that includes valuable information about Best Management Practices and Tools for Varroa Management Guide.
This publication has the latest information available for managing honey bee colonies and controlling varroa mites. Our local bee club has even used this publication to help teach beginning beekeepers at our beginners class.
Did I mention it was free?
