Our Mason Bee Observer nesting trays are an easy, fun and safe way to peek into the secret life of bees.


Add our Bee Observer nesting tray to your Chalet, Cottage, or Tower bee house and watch female bees build their nests. The clear window also lets you watch mason bee larvae develop without disturbing the bees.

Mason Bee Observer (8mm Tray): In the spring, you can watch female mason bees build mud walls and pollen loaves for each egg. When the female bees are done nesting, remove the Bee Observer and from the comfort of your home or classroom, watch the mason bee larvae eat, grow, and spin their cocoons. You can also see pests like pollen mites or chalkbrood develop.
