Boost your garden's productivity by providing a happy home for peaceful, non-stinging Mason bees. Slightly smaller than honeybees, Mason bees are incredible pollinators. Each one visits as many as 1000 blooms per day — 20 times as many as a honeybee! Hang this natural bamboo house against a tree or wall where it will get morning sun and attract bees. Female bees fill the bamboo tubes with their eggs, and nectar and pollen for the young to eat.
