Bumblebee House

This is a bumble bee house. They can either go into it in the wild or in my case, for the ones I have placed in there from hive relocation. The opening hole is 1 inch; and the roof line has vent holes along with plenty of drain holes at the base. This was laid out to have an exterior and interior wall with an air gap between them to help insulate and keep cool in the summer. See photos for light transparency, this does not leave them in complete dark, but dim light. I am sure people can find several ways to secure this down, but the designed is intended to be screwed down to sturdy natural wood. Do not attach to pressure treated or ceder. The house itself is meant to be secured down by 1" #10 pan head screws or truss head. I would not use tapered screws as this will easily damage it. The underside has built in scaffolding to allow for ventilation and isolate rows to help keep pest away and manage air flow. Front is held on with 16 #6 6-32 screws that can be 7/16 to ¾ inch long.
