Honey bees in house nesting box
Hi all, we have for many a year now had a concrete swift box built into the wall of our extension, just below the eaves. This weekend we heard bees and noticed them using the box. We don’t mind, but just wanted to check that we should leave them and not be concerned? They are making a bit of a mess of the entrance to it (it was pointed white so think it may just be pollen?!) and believe them to be honey bees as I know mason bees are solitary and they are definitely not wasps or hornets. Any thoughts or experience welcome! Thanks.
