If you’re a homeowner who enjoys spending time outdoors, chances are you’ve seen buzzing insects flying low over your lawn or vanishing into small holes in the soil. Many of these are wasps that live in the ground — a surprisingly diverse group that builds nests underground rather than in trees, eaves, or wall voids. Some are social and defensive, others are solitary and almost completely harmless, and a few aren’t wasps at all but ground-nesting bees that look similar at a glance.
Aerosol cans are the wrong tool for a nest in the ground, because the spray can't reach down the tunnel. What works is an insecticidal dust like Sevin 5 dust puffed into the entrance with a bulb duster after dark. The dust coats the workers as they come and go and reaches the whole colony. For anything that might be a yellow jacket nest, I also wear this upper torso beekeeping suit. It looks ridiculous, but trust me, learn from my mistake.
This guide focuses on identifying which species live in the ground, understanding their behavior, and deciding whether to coexist with them or remove the nest. If you’ve already decided a nest needs to go, see our step-by-step ground wasps removal guide and our guide to wasps in grass. For close-up nest and entrance-hole identification, our underground wasp nests guide goes into detail.
The wasps you’re most likely to find nesting in the soil around a home fall into two very different groups:
Telling which group you’re dealing with is the single most important step, because it determines whether you have a genuine hazard or a beneficial insect that’s best left alone.
Underground nests offer real advantages. Soil provides stable temperatures, insulation from heat and cold, and protection from many predators and from rain. Bare or sparsely vegetated ground is easy to excavate, which is why you’ll often see ground-nesters concentrated in dry lawn edges, garden beds, sandy patches, slopes, and areas with thin grass. Understanding why they chose a spot also helps with prevention: dense, healthy turf and well-watered soil are far less attractive to most ground-nesting wasps.
Yellow jackets are the most common — and most consequential — wasps that live in the ground around homes. A single underground colony can grow to thousands of workers by late summer, and because the nest is hidden, it’s easy to disturb accidentally while mowing or gardening. They are the ground-nesters most likely to sting in defense, and a disturbed colony can deliver many stings at once. For full colony details, identification, and removal options, see our Yellow Jacket Wasp Guide.
Cicada killers are large, intimidating-looking solitary wasps (up to 1.5–2 inches) that dig burrows in dry, sunny, bare soil. Despite their size, they are remarkably docile — males can’t sting at all, and females sting only if grabbed. Each female hunts cicadas to provision her own burrow. They’re often mistaken for a dangerous swarm when really it’s just many individual solitary wasps nesting near each other. Learn more in our cicada killer wasp guide.
“Digger wasp” covers several solitary species, including the striking metallic-and-orange great golden digger wasp. These wasps excavate individual nest tunnels and stock them with paralyzed prey such as grasshoppers and katydids. They are non-aggressive pollinators-and-predators that benefit the garden. Our digger wasp identification and behavior guide covers the group in detail.
Sand wasps are solitary ground-nesters that favor loose, sandy soil. They prey on flies and other insects, making them useful natural pest control. Like other solitary wasps, they have little interest in people.
Scoliid wasps are robust, often hairy wasps that burrow into the soil in search of beetle grubs — including the larvae of destructive lawn pests like Japanese beetles. They’re beneficial, slow-flying, and very unlikely to sting.
Not every insect emerging from a hole in your lawn is a wasp. Several important ground-nesting bees also live in the soil, and they are nearly always harmless pollinators:
These bees are vital to gardens and the wider ecosystem. Because they’re solitary, there’s no large colony to defend, so they almost never sting and are best left undisturbed.
Distinguishing the two helps you respond appropriately:
| Feature | Ground-Nesting Bees | Ground-Nesting Wasps |
|---|---|---|
| Body | Fuzzy, hairy, robust | Smooth, shiny, often narrow-waisted |
| Color | Often dull brown, black, or metallic | Bright yellow-and-black or reddish |
| Behavior | Calm, focused on flowers | Yellow jackets defensive; solitary wasps calm |
| Nest | Small soil mounds, solitary | Yellow jackets: single hole, heavy traffic |
| Role | Pollinators | Predators (and some pollination) |
If you see a steady stream of striped insects pouring in and out of one hole in mid-to-late summer, you’re most likely dealing with a yellow jacket colony. Scattered individual holes each with one occupant point to solitary bees or wasps. For more on telling species apart by their burrows, see our ground wasps identification guide.
Often the insects themselves are too fast to study, and the hole in your lawn is the best clue to what’s living there. The appearance of the entrance — its size, the soil around it, how many there are, and how busy it is — usually tells you the species before you ever get a close look at a wasp.
| Clue | Yellow jacket | Cicada killer | Mining / digger bee |
|---|---|---|---|
| Hole size | ~½–1 inch (thumb-width) | ~½–¾ inch, oval | Pencil-width (¼ inch) |
| Number of holes | Usually one entrance | Many separate burrows clustered together | Many scattered holes |
| Soil around it | Little or no mound | Distinctive U-shaped or fan-shaped mound of loose soil | Small conical “volcano” mound |
| Traffic | Constant heavy two-way stream | One wasp per burrow, coming and going | One bee per hole, calm |
| Time of year | Builds through summer, peaks late summer | Mid- to late summer | Mostly spring |
| Location | Lawn edges, under shrubs, slopes, old rodent burrows | Dry, bare, sunny soil and sandy banks | Bare or thin-grass patches |
The single most reliable signal is traffic at one hole: a yellow jacket colony produces a dense, continuous flow of insects in and out of a single opening, while solitary species (cicada killers, digger wasps, and ground bees) each tend their own burrow and never share an entrance. A cluster of many holes in dry soil that looks alarming is almost always a group of harmless solitary nesters, not one giant colony.
Safety note: identify the hole from a distance. Never put your face, hand, or a hose nozzle near an active opening to inspect it, and never block a hole to “see what happens” — a sealed yellow jacket colony will simply dig a new exit, sometimes into a wall void or your home. For close-up entrance photos and structural detail, see our underground wasp nests guide, and for the holes that appear in lawns specifically, our wasps in grass guide.
It depends almost entirely on whether they’re social or solitary:
If you are stung, our ground wasp sting treatment advice and detailed wasp sting treatment guide explain immediate care and warning signs of a serious reaction. Remember that wasps can sting more than once, so move away from a disturbed nest calmly and quickly.
Despite their fearsome appearance, most wasps that live in the ground are genuinely beneficial:
A yard with solitary ground-nesters is often a sign of a healthy, balanced ecosystem.
Use this simple decision framework:
Leaning toward coexistence when:
Leaning toward removal when:
If you decide to leave a nest alone:
If you’ve identified an aggressive yellow jacket colony in a high-traffic spot, removal is reasonable — but do it safely. Underground colonies are large and react fast, so this is one situation where professional help is often worthwhile, especially for big late-summer nests. For step-by-step methods, timing, and product guidance, see our dedicated ground wasps removal guide, our wasps in grass guide, and the in-depth underground wasp nests guide. Always wear protective clothing, treat the nest after dark when wasps are inside, and keep a clear escape route. If you’re at all uncertain, contact a licensed pest control professional.
The most common are yellow jackets (social), plus several solitary species: cicada killers, digger wasps, sand wasps, and scoliid wasps. Ground-nesting bees such as mining and sweat bees also share this habit but are not wasps.
Solitary ground wasps abandon their burrows after a single season and don’t reuse them. Yellow jacket colonies die off each fall — only new queens survive winter, and they start fresh nests elsewhere in spring rather than returning to the old hole.
Yellow jackets are the most common social ground wasp, but “ground wasps” is a broader term that also includes solitary species like cicada killers and digger wasps. See our ground wasps guide for the full lineup.
Yellow jacket nests can extend a foot or more below the surface and grow to the size of a basketball or larger by late summer. Solitary burrows are typically much smaller and shallower. Our underground wasp nests guide covers nest structure in detail.
Solitary ground wasps almost never sting unless handled. Yellow jackets, however, will sting to defend their colony if you walk over, mow, or vibrate the nest — so a confirmed yellow jacket nest in a busy area is worth removing.
Watch the traffic and the soil. A single hole with a heavy, constant two-way stream of striped insects in summer is almost always a yellow jacket colony. Many scattered holes, each with one occupant, point to harmless solitary wasps or ground bees. Mining bees leave a small conical “volcano” of soil around a pencil-width hole in spring; cicada killers leave a larger U-shaped mound. See the hole identification table above for a full comparison.
Yellow jackets and most ground-nesting wasps are active during daylight and warmth, with peak traffic during the warm midday and afternoon hours. They return to the nest and become inactive after dark, which is exactly why any removal should happen at night or before dawn. See our guides on when wasps are most active and what time wasps return to their nest for the full daily timeline.
Ground-nesting wasps prefer bare or sparsely vegetated soil that is easy to excavate — dry lawn edges, sandy patches, slopes, thin-grass areas, and abandoned rodent burrows are all common sites. Yellow jackets in particular often reuse existing cavities in the soil. Maintaining dense, healthy, well-watered turf and filling old rodent holes makes your yard far less inviting to ground-nesters in the first place.
Solitary ground wasps finish their nesting cycle in a few weeks and abandon the burrow for good. Yellow jacket colonies last a single season: they grow through summer, peak in late summer to early fall, then die off with the first hard freezes. Only new queens survive winter, and they start fresh nests elsewhere in spring rather than reusing the old hole.
