Do Wasps Build Nests in the Ground?

When you picture wasp nests, you think of paper lanterns in locations like under the eaves or hanging from your porch ceiling. 

These spots are predictable. 

Here’s the twist: some wasps skip the tree branches entirely and build their homes right under your feet. 

Yellowjackets in particular love to set up shop in old rodent burrows, turning a quiet patch of lawn into a sting zone. 

The worst part is that you won’t notice this nest until the mower rolls over it… 

…and then it’s too late.

Yes, Wasps Do Build Nests in the Ground

It usually starts with a queen. In spring, she’ll crawl into a pre-dug hole, often an abandoned rodent burrow or a sheltered patch of soil. There, she begins building a paper-like nest by chewing wood fibres into pulp. As summer progresses, the colony grows rapidly.

• Early summer: a handful of workers
• Mid-summer: hundreds
• By late summer and early fall: thousands of yellowjackets are buzzing beneath your lawn

Unlike bees (that die after one sting), yellowjackets sting repeatedly, and they’re fiercely protective of their nests. If you kill one near the nest, it will send out a signal, and soon you’ll be at war. That makes ground-nesting wasps a much bigger problem than a papery nest hanging high out of reach.

Note: Not every hole in the lawn means trouble. Solitary digger wasps also burrow into soil, but they’re harmless and rarely sting. It’s the yellowjackets you need to watch for since they defend their colonies aggressively.

How to Spot a Yellowjacket Nest

The tricky thing about ground nests is that they’re hidden in plain sight, which is what makes them dangerous.  

Signs to look for:

• A small entrance hole in the soil: Usually about the size of a quarter. Could be in lawns, garden beds, mulch, or near foundations.
• High buzz traffic: Wasps flying in and out of the same spot like a busy airport.
• Buzzing close to the ground: You’ll notice activity when mowing, gardening, or walking nearby.
• Worn patches of soil or bare spots: Spots where they shouldn’t be.
• Fresh dirt piled around the entrance: Similar to what you’d see at the opening of a burrow.
• Increased wasp activity in one area at specific times of day: Morning and late afternoon are often busiest.
• Aggressive behaviour when you approach: Wasps may circle or dive near the ground before you even see the entrance.
• Multiple entry holes in the same area: Larger nests can have more than one “door” for traffic. 

Where You’re Most Likely to Find Ground Nests

Ground-nesting wasps aren’t picky, but they do favour certain spots. 

• You’re most likely to find them in abandoned rodent burrows, soft soil, garden beds, and mulched areas. 
• They’ll also settle near man-made structures like sheds, fences, or the edges of patios where the soil stays undisturbed.
• Even lawns can be fair game if the ground is loose and dry. Because entrances are so small, nests often blend in until you notice traffic in and out of the hole.

Why DIY Treatment May Be Risky

It’s tempting to deal with a ground nest yourself. A quick internet search will turn up dozens of DIY “solutions”. We’ve covered the very topic in detail before. 

Here’s the problem with DIY:

• It can be dangerous. Agitated yellowjackets don’t just sting once; they swarm.
• It may be ineffective. These nests go deep. Surface-level treatments rarely wipe out the entire colony. The wasps you miss will rebuild.
• It’s harmful. Gasoline or harsh chemicals can contaminate soil and groundwater, harming plants, pets, and beneficial insects.
• It can backfire. Incomplete treatments may cause the colony to relocate… closer to your house.
• You can’t see what’s underground. Nests can stretch wider and deeper than expected, meaning your “one quick pour” barely scratches the surface.

Safe Options for Dealing With Ground Nests

If you spot a ground nest or a wasp in your yard, the first step is resisting the urge to charge in with boiling water or a spray can. Ground nests are dangerous, and the safer approach is patience and caution.

Here are the safest routes:

• Keep your distance. Rope off the area and keep kids and pets away. Don’t mow, weed-whack, or garden directly over the nest. Even vibrations from equipment can trigger an attack.
• Mark the location. If the entrance hole is in a high-traffic area, flag or stake it discreetly so no one stumbles across it by accident.
• Time your observation. Wasps are busiest during the day. If you need to confirm activity, do it from a distance in the morning or late afternoon when traffic is most obvious.
• Don’t block the entrance. Piling soil, rocks, or mulch over the hole won’t solve the problem and usually makes wasps more aggressive.
• Avoid DIY flammables. Gasoline, kerosene, or matches near a nest are ineffective and, most importantly, a fire hazard.
• Call professionals. Licensed wasp control experts have the equipment and protective gear to neutralize nests safely. They use targeted treatments that eliminate the colony without spraying chemicals everywhere.
• Plan for prevention. Once the nest is dealt with, take note of the location. Wasps often reuse areas year after year, so filling burrows and maintaining soil can help deter future nests.

How Do You Prevent Ground Nests in the Future?

Once the current nest is gone, prevention becomes the name of the game. Wasps are opportunists. If your yard has the right conditions, they’ll be back next season.

Here’s how to make your yard less inviting:

• Fill in holes and burrows. Old rodent burrows, gaps in the soil, or spots left by tree roots are prime real estate for yellowjackets. Fill them with soil or gravel to take away their ready-made shelters.
• Keep lawns and gardens tidy. Overgrown grass, piles of leaves, or stacked firewood provide shady cover where queens can start new nests in spring.
• Secure garbage bins. Wasps are drawn to protein scraps and sugary residues. Use bins with tight-fitting lids and wash them regularly to keep odours down.
• Clean up outdoor attractants. Cover sugary drinks at barbecues, clean up fallen fruit promptly, and rinse out recycling. Even small amounts of soda or juice can attract wasp scouts.
• Watch early activity. In spring and early summer, look for wasps repeatedly flying to the same spot in the ground. Addressing a small starter nest is far easier than waiting until a colony is hundreds strong.
• Maintain outdoor spaces. Regularly aerate and reseed bare lawn patches, and keep mulch layers balanced. A healthy, even yard leaves fewer spots for wasps to claim.
