Spring Reusable Wood Trays for Mason Bees - 48-Hole


Availability: In stock

Short Description

Spring reusable wood trays for mason bees with 48 nesting holes. Scents from reused wood trays attract nesting mason bees. Easy to open and clean to remove and harvest mason bee cocoons.



Mason bee nesting trays are perfect for the serious mason bee raiser!

Trays should be placed within a bee house to protect from rain.

  • Precision crafted of Northwest alder.
  • Nesting holes are 8mm in diameter, the preferred size of spring mason bees.
  • Houses 25-30 female mason bees, about 80 total cocoons.
  • Front is lightly burnished, creating a visual pattern that helps the mason bee find home.
  • Cardboard removable backing protects the mason bees and encourages nesting.
  • Side notches lock into neighboring trays, retain alignment, and help block pests from entering on the side.


  • Reusable wood trays control year-to-year costs.
  • Easy to open and clean to remove and harvest mason bee cocoons in the fall.
  • Scents left from previous mason bees will attract next year's generation of mason bees.
  • Wood is natural habitat for mason bees and provides both insulation and moisture control - a natural wicking effect that pulls moisture from the wet pollen loaf, preventing moldy cocoons.

If building your own bee house, ensure that you have plenty of overhang space!

Additional Information

Spring Use
  1. Trays will arrive with elastic bands around them to hold trays together and are to be left in place.  Note:  Cardboard on back of trays is for closing off the back side of holes and should not be removed.
  2. Provide 2-3" of overhang to protect the trays from rain. Placing tray within a bee house is perfect!
  3. When spring mason bee activity has ceased remove tray from bee house and store in a garage or well ventilated shed (see below).

Summer Storage

Store the filled nesting trays with holes facing up. We recommend storing the trays in a BeeGuard bag or other container that will allow air to circulate and keep pests out. Store protected over summer in an un-heated garage.

Fall Harvesting and Cleaning & Storage of Tray

  1. Remove green elastic bands, setting cardboard backing to side. Separate trays one at a time, removing cocoons as you go.
  2. Clean trays with a dry scrub brush and restack them.
  3. Re-strap the trays using the elastic bands, being sure to include the cardboard backing.
  4. Store assembled trays in garage or shed for use next spring.
