REFILL for LARGE Mason Bee House (includes 100-120 bees)

Host mason bees for the spring season! A Large Insert for who have a permanent bee house or shelter in their backyard, which can support a large number of mason bees. Perfect for the avid gardener or backyard orchardists!

This package includes: large mason bee nesting block (rough dimensions 5.5 x 6 x 6 in) and 100-120 mason bee cocoons inside of two white emergence tubes. If you do not already have a bee house, rent our Large Kit. 

Mason bees can be shipped to most of the U.S. They cannot be rented in Hawaii, Alaska, Mississippi, Alabama, Georgia, Florida, and Louisiana due to weather conditions not being suitable for our bees. This kit cannot be mailed to P.O. Boxes. 

OUR SERVICE INCLUDES FALL CLEANING: At Rent Mason Bees we offer a way for people to be a part of their food source and help native solitary bee populations, but not have to worry about doing the fall cleaning which is critical when hosting mason bees. When you rent our bees, you keep your black house and send your nesting blocks back to us in September. We will then harvest and clean all your cocoons to remove harmful predators like pollen mites, Houdini fly larvae and chalkbrood. Then, we sterilize all your nesting blocks over fire and flame to burn any remaining predators. After they’re all cleaned and dried, we place them on a light table and pick out any non-viable bees. They are then placed in cool storage to safely hibernate over winter. The bees we send you will be healthy, strong and eager to pollinate your blooms.
