MDF-Boards and Blocks

Professional nesting aids for mason bees made from one side milled MDF boards with 10 holes each. For an easy extraction of cocoons and parasite checking. Holes optionally with a diameter of 8 or 9 mm. Dimensions: 16 cm x 16 cm x 1,6 cm.

The boards can be connected to blocks with any size.

Place the blocks on a rain protected, dry spot. They can be opened during the winter season to extract the cocoons from the boards and check them for parasites. Clean the boards afterwards before rebuilding the block for the next season.
