If you observe any of the following telltale signs you may have Ground Bees

  • Dozens of mound-like dirt hills with dime size burrows
  • Single bee entering and exiting these burrows (females)
  • Low flying large bees hovering over the burrows (males)
  • Areas of note are in dry soil or bare patches in the lawn or garden
  • Starting in Early Spring

Ground Bees are beneficial insects that perform an important role as pollinators. Ground bees are solitary bees. Females will build a nest in dry soil and mound it around the entrance. She then fills the hole with pollen and nectar for her offspring. One female bee is responsible for the maintenance of her own burrow. Males fly over burrows patrolling for potential mates.

Do Ground Bees Sting?

Ground bees are not aggressive but will sting if they feel threatened. Only the female has the capability to sting. Males may act aggressively around nesting areas but they do not have stingers.

How do I Control Ground Bees?

Unless you have a family member that is allergic to bee venom it is best to leave them alone. Pesticide application is not recommended for ground bees. They are beneficial pollinators, they are not aggressive, and their nesting behaviors is limited to spring and is short lived. The best and least toxic method to control ground bees is to begin watering the area with a full inch of water weekly. As ground bees prefer dry soil, water will make the area less desirable. In gardens, a thick layer of mulch will discourage nesting.
