Mason Bees

Asked March 30, 2019, 12:33 PM EDT

I bought a Mason Bee hotel(large house) for bees and I need to know how many bees to buy and what kind for the N Oregon Coast. When is the best time to hang house with bees on South side of a structure. Thank you for information.

Thank you for your question. The best time to hang the house is now! The females are looking for housing for their eggs. Hang it at eye height on the SE corner of a building that has eaves, so rain doesn’t wash away the mud the females will cap it with to protect the eggs, which will emerge about now next year. Here is much more information: https://catalog.extension.oregonstate.edu/sites/catalog/files/project/pdf/em9130_0.pdf Good luck!
