What are Mason Bees?

solitary-bee-3-on-kale-feedinglMason Bees

Mason Bees are active during the spring and/or  summer.  During the winter they hibernate, waiting out the cold winter to emerge the following spring.  Immediately after emerging from their cocoons, they mate and the cmating-beesycle begins again. The overwintering period, allows us to harvest cocoons from their nests and examine and clean them to ensure we only sell healthy cocoons.

Beediverse sells Mason Bees in sets of 10-plus a few extra.  The sets of cocoons are contained in small cardboard boxes.  It is easy to place our cocoon boxes adjacent to nesting material.  Our California bee permit number is included towith shipments to this state.

Availability of cocoons. Cocoons are harvested in September and are available from October onwards. When cocoons are NOT available in stores set out a home for mason bees. This will likely attract Mason Bees and set up a little colony by itself.   For example, if a nest is set out in Seattle (WA) or Vancouver (BC), there is a good 75% chance that Mason Bees will nest in your Mason Bee home. This is because many gardeners are managing Mason  Bees in Seattle and Vancouver.  Therefore there are many Mason Bees in the area.
