Mason Bee Nest Care SPRING: February – May

by - 10:09 PM

You can release your mason bees anytime from February until May. You can delay their dormancy by placing them in a cool environment below 55 degrees, but do not hold them past May because they may starve and die. Place your mason bee nest on an east or southeast facing wall under the eaves of your house or shed. Fill your nest with new nesting material (tubes and liners). Next, place your dormant bees that you had cleaned and stored over winter on top of the nesting material or if you purchased one of our mason bee houses, place the cocoons in the lower hatching box area and secure the faceplate.

In a few weeks you will start to see some activity. The males will emerge first and will be very lethargic. These new little guys are just stretching their wings and ready to start pollinating!

A couple of days after the males emerge, you will see a lot more activity when the females emerge. These are much larger than the males (about twice in size). Mating will occur and also lots of pollination. Be sure to put a pot of mud near the nest. This will help the bees when constructing the cell walls between each egg chamber.

Now, you just need to sit back and enjoy your little bees. They will pollinate up to 100 yards away and several times more than honeybees!

  1. We just bought some more Mason Bees from Michelle. She is very knowledgeable and is so willing to share as much as she can about the bees. I had a GREAT success with her bees in the past. My normally VERY low producing plum tree actually lost a limb or two when I did not realize how well the bees did their job. Going to spread the wealth around the property this year. SOOOO happy to have met Michelle and to learn that these bees are so docile and effective. I am normally rather fearful of bees. I also signed up for the bee emails to help me stay on track taking care of my bees!
