Posted a few photos to show this easy wasp deterent
Buy a piece of cable trunking ( b and q sell it amongst others) the one with a sticky back is best. Cut it to a suitable length, cut a hole in the back with a sharp knife or saw. Only take the very back out enough to go over the bee entrance. Block one end with something like a piece of plastic. Stick it over the entrance. You can now slide the front bit of the trunking to make the tube as long as you want. The bees are using it with no problem. I had to put a piece of wood underneath as the entrance wasn't at floor level and it helped the bees climb over the ledge. No wasps seen entering since I put it in place.
Note the orange pollen they are still bringing in in quantity.
