Nesting trays (set - 50 units) for Mason Bee (osmia rufa / bicornis)
A set of 5 BioDar System reusable nesting trays, creating up to 100 nest channels with a diameter of 8 mm and a length of 14 cm.
Hatching cassette
The cassette is used to give shelter to the cocoons, for the incubation of bees and elimination of parasites. It is built of wood, and its internal structure helps recognise parasites, which can occur in the bee cocoons, preventing from their coming out (e.g. bee fly Anthrax anthrax).
