Hubs and I made this mason bee post about a month ago, and the bees have finally started moving in! We drilled holes into an old fence post - they're about 1/4" wide and go almost all the way to the back of the post.
We stuck the post in our backyard facing east. And now, a month later, mason bees have visited and laid their eggs. How exciting is that? (Unless Hubs is playing a trick on me and filling in the holes with mud himself.)
I think this project would be fun to do with children! Mason bees DON'T sting, and I can't wait to start watching them pollinate my flower beds. I've heard that watching bees is more fun that watching television. I almost believe it because it's been pretty darn fun just staring at the post!
This video showed us how to make our bee post. We didn't do the roof part, and it seems like it's still going to work. Beware, the mason bee song on this video is almost too catchy...
