The Backyard Bee Project

What are mason bees?

Mason Bee is a general term for any bee species in the genus Osmia. They are tunnel-nesting solitary pollinators that use mud or clay to seal the opening of their homes. These bees are native to North America and the Puget Sound region alone is home to over 18 species!

These solitary bees are docile and are excellent pollinators, 120 times more effective than honey or bumble bees! Mason bees emerge in early spring, before other pollinators are active. This makes them vital for pollinating early blooming native plants and fruit crops.

Why are they important?

Mason bee populations are shrinking due to habitat loss and poor nesting options. Raising bees in a mason bee house can help support their populations, increase the productivity of your garden, and help you feel more connected to your ecosystem. It’s also a great way for kids and adults alike to learn about insects. And the best part? They don’t sting!

Why raise mason bees?

  • Provide hollow stemmed plants that can provide additional shelter

  • Plant native plants like:

    • Oregon Grape

    • Evergreen Huckleberry

    • Elderberry

  • Incorporate fruit trees

  • Plant gardens with successional blooms for a consistent food source
