It was a great day again on Sunday so I took the opportunity to wield the expanding foam again. The plan was to do two things:
- modify our "triple 3-into-1 tube" set of fake entrances to be covered in moss and look more realistic - with the entrance holes much more vertical standing so they can be seen easily from above.
- create an additional nest site from an old poster tube - the idea was to site this amongst the longer grass where the bumblebees have been nest searching, to make it look like a mossy embankment.
It was all very easy - I've documented the steps in pictures below.
First i made a cardboard base for the "nest tube" and covered it in "bin bag" plastic. The plastic will go face down, to stop the cardboard getting damp and rotting. The top side will be protected by the expanding foam.
Next, the same trick for our "3 into 1" tubing, which goes to a nest box. I made a cardboard wedge from an old box and waterproofed the same way. Note, I poked drain holes along the tubes.
