How to deter birds and paper wasps

The large gap between your nesting block and the roof of your black house is also a great nesting site for birds and paper wasps. You can deter them by stuffing the space with natural yard material and make a cute landing pad for your bees and fill the gap. If you don’t have any yard material, wadded up newspaper will also do the trick.   Extra bonus… it will also help keep your white bee emergence tube in place.
