Sweat Bees

Underground Nesters

Sweat bees, also known as halictids, are second only to honey bees in terms of population. Many of them have metallic-colored green bodies, often with red or yellow stripes. They build nests underground or in rotting wood and rarely grow over three-quarters of an inch in length.

How Did Sweat Bees Get Their Name?

While foraging, these insects obtain pollen and nectar from a variety of common flowers. However, sweat bees must supplement their diets with salt and moisture. This is often accomplished through feeding on human sweat, so the pests can become nuisances during hot days.


Unlike honey bees, sweat bees don't produce honey and avoid making nests in attics or wall voids. Still, they sometimes live among buildings, sheds, and patios that contain exposed or damaged wood.

Sweat bees are generally docile, but females can deliver a mild sting if swatted or aggravated. At times, they are known to swarm in the hundreds.


The pests love burrowing through bare soil in sunny locations. Property owners with treeless, well-lit yards often experience infestations.
