Bumblebee nest box – Double wall

Description

Our nest boxes are tested by bumblebee enthusiasts. Double wall bumblebee nest is made of 18/15 mm waterproof birch plywood with additional air layer between walls.

Our nest boxes including a passive pest protection:

• Protective flip doors.
• Vent protected by fine mesh with diagonal 0,2 mm (melittobia wasp and freshly hatched caterpillars of wax moth can pass diagonal larger than 0.3 mm) and additional aluminum mesh to protect fine mesh against biting through bumblebees.
• Additional cap to vent, working as a trap for wax moths, which can go in, but can’t go back out.
• Well sealed inner space with bumblebee nests, using a polycarbonate plate tight fitting a wooden edge.
• Legs fitting to plastic bottle caps, which, if filled by biologically degradable oil to motor saws, works as a barrier to a crawling insects, such as ants.
