All about Mason Bees

Blue Orchard Mason Bees are expert pollinators and DON’T sting (the males don’t even have a stinger). They are metallic blue/black and are smaller than typical honeybees (so they look like flies). Bee populations have dropped by 50 percent in the last 25 years! Habitat loss, climate change and pesticides have all contributed to this decline. But we can help by making backyard habitats for these solitary critters!

Re-useable Mason Bee Home Materials

  1. Container (empty coffee can, flower pot)
  2. Tape
  3. Bath tissue rolls, brown paper or newspaper.
  4. Pencil
  5. Scissors
  6. String
  7. Peat moss (optional)

Remember to build with an adult!

1. Prepare the Container.

Thoroughly clean it, inside and out. If using an
empty coffee can or similar, remove the lid but
leave the bottom intact. If using a flowerpot,
cover the drainage hole with paper and tape.

2. Make Nesting Tubes.

Create a nesting tube by first cutting, then
rolling the tissue rolls (or paper) snugly around a pencil to make a
sturdy tube. Secure with a few pieces of tape, and gently slide out
the pencil. Close one end of the tube by covering it with tape.

3. Assemble the Bee House.

Place each nesting tube inside the container with all open ends
facing out. If available, add moss in the gaps between tubes for
insulation, support and a comfortable environment. Tie the sting
tightly around the container so you can hang it. (Or bunch holes in
the side of the container and knot the string inside)

4. Find the Right Site.

Choose a south-facing spot in your yard that
will be protected from rain, and hang it about eye level. Trees and
fence posts are natural choices if available.

5. Housing Care.

In the summer or fall careful take out the rolls
and empty the bee cocoons from them. Store cocoons in a dark and
cool place until early spring when you will set them beside your
bee house, with brand new tubes that you now know how to make!

6. How to Encourage more Mason Bees to Visit!

  • Set up more than one mason bee house in different locations.
  • Have plenty of flowering plants growing nearby to provide the
    bees with nectar and pollen.
  • If you notice birds pecking at the bee house, cover the entrance
    with chicken wire.
