This week I have been busy setting up yurts to house my mason bee cocoons. This is critical in areas where spring weather may be cool and wet. The inside of a yurt environment provides mason bees with warmer temperatures than outside temperatures. These warmer temperatures are more suitable for developing bees and growing bees successfully. For this reason, yurts or similar type structures are the way of the future for mason bees.

Our newest yurt, model D27 or D27Yurt is compact (3ft in diameter) sturdy, can hold 27 highrises and is easy to assemble. Each yurt can be put together in 2-3 hours with a screwdriver, drill and a pair of pliers. Three D27Yurts will be set out in different locations to test their effectiveness.

I am excited to have all cocoons set into yurts this year. I will be setting up a total of 5 yurts. Each yurt has the capacity of holding 648 nesting tunnels at each of 3 levels. a capacity of 1944 nesting holes.  At each of 3 levels, there is space for 9 Highrises (72 nesting tunnels per Highrise). Of course temperatures will be higher at the top levels compared to the lower levels, but more about differing temperatures inside the yurt in later blogs. Two yurts in use were designed and made by Charlie F. The remaining yurts will be the new D27Yurt.

This is Charlie’s yurt.  The tarp is 3 years old and is still in good shape.  We checked for holes in the tarp and found a few where the wood rubs the tarp.  We taped some duct tape over the few holes we found.  It is ready for hanging Highrises and setting out cocoons.

I have even set up a D27Yurt on the deck of my home. Previously I had 3 boxes (2 x 2 x1.5ft) attached onto the wall of my home. In each box I used to set out an assortment of nesting trays and houses. This site is less attractive now because my peach tree shades that part of the house. The deck receives more direct sun than any other part of my garden- so it should be a good site for my bees. Yesterday, the Highrises were hung into a D27Yurt at the home site. The sun came out for a brief period and temperatures rose to 80F inside the yurt! It is nearly time to set out the cocoons. The Peach tree is beginning to fill out their buds.
