The Varroa Board is designed to slide into a slot on the underside of the HiveIQ Hive Base. The tray should be placed into the slot for short periods of time to monitor varroa infestation levels. It should be left out at all other times except for early spring when it can be used to warm the brood chamber to encourage faster spring build-up.

The Varroa Board is also useful if you need to fumigate an empty beehive for parasites like wax moths. By inserting the varroa plate, it seals the box retaining any gas from the fumigation treatment.
