Joe predator proofs his full mason bee nests

The screen dangles from a screw at this nest.

Joe S.  from Burnaby, has come up with a very simple way of protecting his nests AFTER bees have stopped flying or when the nest is full ( Note:  Mason Bees tend to avoid nests with screens).

The screen is not fixed into place but dangles and moves with the wind, making it very awkward for woodpeckers to land at the nest.

Paperclips are used here to give the screen
the proper positioning over the nesting holes.
