Biology and Habits

Mining bees are a large group of small solitary bees that nest in the ground. They may be found in large aggregations around loose soil or sandy areas, creating small tunnels in the ground, where each cell is provisioned with pollen and nectar. Females are capable of stinging, but rarely do so. Mining bees are excellent pollinators and play a role in pollinating many early blooming plants, including cherry, apple, blueberry, and other flowering plants. 

Control

While these bees are not normally a cause for concern, occasionally they may nest in areas frequented by people or pets. Common locations include soil garden beds, sandboxes, playgrounds, and occasionally in bare areas in yards. Control is discouraged unless populations become large and bothersome. Dusts or aerosols can be applied to the entrance of the nest to eliminate adults and larvae. Eliminating bare-ground areas will discourage bees from returning the following year.
