Finding wasps flying low over your lawn or disappearing into small holes in the soil can be alarming. These are ground wasps — a broad category of wasp species that build their nests underground rather than in trees, eaves, or walls. Understanding what species you’re dealing with, whether they pose a real threat, and how to remove a wasp nest in the ground safely will help you make the right decision for your family and yard.
For non aggressive wasps I've had great luck spraying the nests with this Spectracide wasp remover in the evening. For more aggressive wasps I also use this rediculous looking upper torso Beekeeping suit. It seems silly, but trust me, it's amazing.
This guide covers the most common ground wasp species, how to identify them, whether ground wasps are aggressive, proven methods for getting rid of them, and what to do if you’re stung. For closely related topics, see our guides on wasps in grass, wasps that live in the ground, cicada killer wasps, yellow jackets, and mud daubers.
Ground wasps are any wasp species that nests in or on the ground. Most are solitary wasps, meaning a single female digs and provisions her own burrow without a colony, but some highly aggressive social species — particularly yellow jackets — also build nests underground. This distinction matters enormously for safety: solitary ground wasps are rarely a threat, while social ground wasps can swarm.
Common ground-nesting wasp species found in U.S. backyards include:
The clearest signs of ground wasps on your property:
If wasps are entering and exiting from a hole at ground level and you see multiple wasps at once, assume it is a yellow jacket colony until proven otherwise. Solitary species are almost always seen one at a time.
Yellow jackets are the ground wasp most likely to cause problems for homeowners. They build paper-comb nests inside underground cavities — frequently in abandoned rodent burrows — and a mature late-summer colony can contain 1,000–5,000 workers.
Identification: ½ inch long, bright yellow and black banded abdomen, no visible hair (unlike bees). They move quickly and hold their wings flat at their sides when at rest.
Nest signs: Steady stream of workers flying directly into a hole at ground level, especially in late July through September. Disturbing the nest entrance (even by mowing nearby) can trigger mass stinging.
See our complete yellow jacket guide for more detail.
Cicada killers are among the largest wasps in North America — females can reach nearly 2 inches long — and their size makes them look terrifying. Despite their appearance, they are solitary wasps that almost never sting humans.
Identification: Large (1.5–2 inches), black or dark brown with yellow markings on the abdomen, rust-colored wings. Males hover aggressively to defend territory but have no stinger. Females are focused entirely on hunting cicadas.
Nest signs: Large U-shaped mounds of excavated dirt around a 1-inch hole, typically in well-drained sunny areas of your lawn. Multiple burrows may be clustered in the same area, making it look like a colony — but each burrow belongs to a single female.

“Digger wasp” is a general term covering several solitary species in the family Crabronidae. They range from ¼ inch to over an inch in length and are typically black, metallic blue, or banded yellow and black.
Identification: Slender body, narrow waist, solitary behavior. You’ll see one wasp at a time entering or exiting a burrow, often carrying a paralyzed insect (grasshoppers, katydids, flies) to provision her nest cells.
Nest signs: Small clean burrow holes in sandy or bare soil. Digger wasps are almost always found in dry, sunny locations. They do not defend their nests aggressively.
Our dedicated digger wasp guide covers identification and management in detail.
This depends almost entirely on the species:
Solitary ground wasps (cicada killers, digger wasps, golden digger wasps) are not aggressive toward humans. A female will only sting if physically grabbed or pinned. Males may hover or dart at you, but males of all wasp species lack stingers. You can walk near their burrows, mow over their territory, and even observe them closely without incident.
Social ground wasps (yellow jackets) are genuinely aggressive, especially in late summer when colony size peaks and food sources become scarce. Yellow jackets will sting repeatedly without provocation if they perceive a threat to the nest. Vibrations from lawn mowers, weed trimmers, and foot traffic near the nest entrance are common triggers. Unlike honey bees, yellow jackets do not die after stinging and can sting multiple times.
Rule of thumb: If you see one or two wasps near a ground hole, they are likely solitary and harmless. If you see dozens of wasps streaming in and out, treat it as a yellow jacket nest and give it a wide berth.
For solitary ground wasps — cicada killers, digger wasps, golden digger wasps — the best management strategy is often to wait. These wasps complete their nesting cycle by late summer, and the burrows are abandoned by fall. They provide real ecological benefits by controlling pest insect populations and loosening compacted soil.
If the location is inconvenient (a playground, heavily trafficked path), you can discourage nesting by:
Yellow jacket nests in the ground require treatment because of their aggression. The safest methods:
Insecticide dust (most effective) Apply an insecticide dust labeled for wasps (e.g., products containing carbaryl or deltamethrin) directly into the nest entrance at night when wasps are inside and cooler temperatures make them sluggish. Do not use a flashlight aimed at the nest — use a red-filtered light, which wasps cannot see. Wear long sleeves, gloves, and eye protection. Repeat applications may be needed.
Soap and water solution Mix 2–4 tablespoons of dish soap per quart of water and pour rapidly into the nest entrance at night. The soapy water suffocates wasps on contact and is a safer option for those who prefer to avoid pesticides. It is most effective on smaller or newly established nests.
Professional treatment For large nests, nests near doorways or play areas, or if anyone in your household has a bee/wasp sting allergy, call a licensed pest control professional. They have protective equipment and faster-acting products that reduce the risk of stings.
Important: Never seal a yellow jacket nest entrance without treating it first. Workers trapped inside will chew through walls, floors, or insulation to find another exit — potentially into your home.

If you are stung by a ground wasp, follow these steps:
Seek emergency care immediately if you experience hives, throat tightening, difficulty breathing, dizziness, or swelling away from the sting site — these are signs of anaphylaxis, a life-threatening allergic reaction.

Consider calling a licensed pest control company if:
Professional pest control is the safest option for yellow jacket colonies discovered in late summer when populations peak. Attempting to treat large nests without proper protective equipment carries serious risk.
Ground wasps range from completely harmless solitary diggers to genuinely dangerous social colonies. Identifying the species correctly before taking action will save you time, money, and unnecessary risk — and may save you from disturbing beneficial insects that are actively helping control pests in your yard.
