Mason Bee Supplies

Mason Bee General Information

Care of Dormant Mason Bees

We are a non-profit 501c(3) organization dedicated to educating our members and the general public about growing good fruit at home.

For many years, a group of our members have been spending their spare time raising mason bees to sell to other backyard fruit growers. Currently, at nine different sites around Portland and the North Willamette valley, members set out new tubes every spring to increase their mason bee populations, making it possible to sell full tubes to others. These bees are home-grown, adapted to the Pacific northwest climate, and extremely hardy.

If you are interested in ordering from us, please take a moment to read these guidelines

We do our best to sort and inspect our cocoons, however it is possible that you may receive a few bees that are not true Blue Orchard mason bees, there may be a few leaf cutter and or hornfaced mason bees (both are excellent pollinators) in your package.

Empty tubes

Empty tubes are cardboard with a thin plastic coating for weather resistance. Tubes need folding in half, as a 12” tube is too deep for bees to use efficiently. We sell bundles of 27 because this is the number of tubes that fit (folded) in one side of a 3” PVC house, or that fills both ends of a 2” PVC house.

If you are buying 3 – 5 tubes of bees, a bundle of 27 empties will serve as nesting space for the first two seasons of your bees. Expect to provide a woodblock or PVC house with one bundle of 27 empty tubes for every 3 – 5 twelve inch folded tubes of bees you purchase.
