Yes, there are mulches that will discourage nesting ground bees. Ground bees dislike such non-organic mulches as pebbles applied as 3-inch (7.62-centimeter) covers.
There are some that live in the ground
hornets ---------- there are a number of bees that nest in the ground..digger bees are solitary bees that will nest in large numbers at time, creating holes along the ground...in arid areas honeybees will nest in old ground burrows...wasps like yellow jackets will nest in the ground..a large wasp called a cicada killer is a solitary wasp that also nests in the ground Lar
Use a spray bee killer for the particular type of bees in the mulch bed. Be careful walking around the mulch as the bees may be inside the mulch as well.
Bumble, digger, mining, and sweat bees are bees that burrow in the ground. They respectively belong to the Apidae, Anthoporidae, Andrenidae, and Halictidaeinsect families. They collectively may be referred to as burrowing, earth-nesting, and ground-dwelling bees even though bumblebees -- which are social and build colonies -- will be excluded from the designation solitary bees.
Killing bees is not recommended, as bees play a vital role in pollination and the overall health of the ecosystem. Instead of killing bees, consider taking measures to prevent them from nesting or stinging, such as removing potential nesting sites or wearing protective clothing. If bees become a significant nuisance or pose a danger, contact a local beekeeper or pest control professional for assistance in safely relocating the bees.
Spray poison around the nesting area
Field crickets, fire ants, ground-dwelling beetles and ground-nesting bees are examples of insects that make dirt castings on garden and lawn surfaces. Ground-nesting bees include metallic green sweat (Agapostemon spp), mining (Andrena spp), polyester (Colletes spp) and sweat (Halictus spp, Lasioglossum spp) bees in North America. The grub stages of such beetles as the invasive Japanese (Popillia japonica) may be implicated.
A nesting and breeding place for bees and wasps.
No, ground bees are yellow and black and about the same size as honey bees
If undisturbed, they won't bother you; however, if you disturb their nesting area by pulling weeds from the ground where the nest is, they will sting. I got stung this morning just that way, and last year I was chased by many bees after pulling weeds and apparently disturbing their nest.
