Don Z emailed me these great photos. Thanks Don. These photos show many interesting things, especially the little drawers that safely store his cocoons while they wait for warmer weather. Safely overwintering cocoon into the spring is a must for successful mason bee keeping.
Note also the colourful patterns on the front of the nesting tunnels. These are patterns and colors help bees return to the correct nesting tunnel. If you find in the spring that mason bees are going in and out and in and out of different nesting tunnels, they need help with a few simple patterns on the front of their nesting tunnels. Safely overwintering and hatching cocoons is a must for successful mason bee keeping.
Successful hatching can only occur if mason bee cocoons are protected from predators and the weather. A cardboard box may work, but cocoons are easy prey for rodents. A simple wooden box with a hole in one side works well. The type of box depends on the number of cocoons. For less than 100 cocoons this new Hatching Hut is a safe and convenient place for not only overwintering but releasing the bees. If you have up to 100 cocoons grab one of two of the hatching huts. They are well made, can easily be cleaned and used year after year. click here for more information about the Hatching hut.
