How to Make a Native Bee Nesting Box

How to Make a Native Bee Nesting Box:

Back in the spring I made a native bee nesting box by drilling a bunch of holes in the long end of a 4 by 6 inch piece of scrap wood. I cut one end of the 4 x 6 at an angle so that I could nail on a makeshift roof made from a piece of 2 x 6. I hung the nesting box on an east facing wall or our house with a picture hanger.

I used three sizes of holes to see which ones would be most popular: 1/4 inch, 3/16 inch and 1/8 inch. All were moved into by, I think, the same native bee within days of putting up the box. This afternoon, when I went to check on the nest to take some pictures for this blog post, I was delighted to see a lot of activity. There were bee butts sticking out of the holes, as well as bees flying in and out. I think they are some sort of mason bee--extra credit to the person who successfully identifies the species:


They move fast, so I was only able to get these two blurry shots. No, they are not Chupacabras.

With the success of this primitive native bee box, I decided to make more nesting boxes to see if I could attract other solitary, native bees. I put this one together with some small pieces of bamboo that I found in a neighbor's trash can:


I think there's a great potential to create works of public art that double as insect nests. For a nice example of this idea see the "insect hotel" designed by by Arup Associates.

We also have a project for a native bee box in our book Making It.
