Hive beetle traps
Different traps can be installed on the bottom board of the bee hive. If the hive has a screened bottom, traps can alternatively be attached to the side walls of the hive. Inside the traps, the beetles are exposed to toxic or adhesive substances.
Beehives with a mesh bottom board (Varroa screen) can be modified so that an oil tray can be placed underneath of the bottom screen which is non-permeable for bees. The mesh size of the Varroa screen must allow passage of the small hive beetle and if possible, the oil tray should be slightly wider than the interior of the beehive, so that also beetles which try to escape from the bees through the screen directly at the side walls of the hive will drown in the oil.
Traps which can be inserted between the frame top-bars are very simple to use. They are simply filled with oil (~5 mm filling level is normally sufficient) and are available in many variants.
For diagnosis, 4 mm corrugated plastic strips can be used (also see FLI supplemental information Schäfer-Diagnose-Streifen, /Schäfer diagnostic strips, Weblink OpenAgrar, in German language only), which however neither kill nor capture the beetles.
