For anyone wanting to save the bees, look into making bee hotels. If you have a power drill and a variety of small bits, easy money. Spend a half hour watching videos, not too much to learn. They're basically free to make if you can lay your hands on some wood or non pressure-treated lumber. Chunk the old one every year and roll an new one.
Damned cool when you see your first guests having waxed off the entrance hole!
