Key strategies for effective Varroa control

• 1. Monitor the infestation in your hives. You need to know if the mite population

is building up faster than you thought or your treatments are not proving

• effective. Don’t just treat and leave it to chance.
• 2. Talk to other local beekeepers about the Varroa problems you experience and

the control strategies you are using. It may then be helpful to work together – for example in coordinating treatments.

• 3. Practice Integrated Pest Management (IPM) using a combination of varroacides

and biotechnical methods. Tiis will give the most effective control.

• 4. Slow the development and spread of resistant Varroa, and minimise the risk of

treatment residues by treating no more often than is necessary – monitoring will help you decide how often this should be.
