| • Treat the nest at night: Dust or wasp spray in the entrance after dark kills the colony with the fewest stings. • Traps manage numbers, not nests: Lure traps and do-it-yourself (DIY) traps cut down on foragers but rarely wipe out a colony. • Call a pro for risky nests: Hire a licensed pro if you're allergic or the nest is large, high up, or in a wall. |
To get rid of yellow jackets in your yard, find the nest, then treat its entrance at night with insecticidal dust or a wasp spray. For risky nests, hire a pest control pro.
This guide covers identification, 9 removal methods, safety, and prevention.
Tall grass hides nest entrances. Lawn Love’s lawn mowing service keeps grass short, so nest holes are easier to spot.
How to identify yellow jackets and find their nest
Getting rid of yellow jackets starts with confirming what they are and finding the nest. Treating the entrance is the only reliable way to kill the colony.
Yellow jackets vs. look-alikes
Yellow jackets have bold black and yellow bands and little body hair, and they can sting repeatedly.
One exception is the bald-faced hornet: black and white, with a white face and a gray, papery nest in the open. Despite its name, it’s a large yellow jacket, not a true hornet, says Jamie Kopco, Ph.D., extension educator with Penn State Extension in University Park, Pennsylvania.
This social wasp guide has details, but here’s how to tell them apart:
Yellow jacket: Black and yellow, with little hair; nests in the ground, wall voids, or shrubs.
Paper wasp: Less yellow, with long legs; builds an open, umbrella-shaped nest.
Honeybee: Much hairier body; usually busy visiting flowers.
Cicada killer wasp: Large and solitary; digs single burrows in lawns and rarely stings people.
If you’re dealing with bees, call a beekeeper instead.
Where to find a yellow jacket nest
The easiest way to find a nest is to watch for yellow jackets streaming in and out of one spot. Many homeowners find a nest only by mowing over it.
Look during the day: Find the entrance while workers are active, and mark it for after dark.
Check common spots: Look along driveways, foundations, rock walls, decks, and shrubs.

How to get rid of yellow jackets in your yard
The most reliable way to get rid of yellow jackets in your yard is to treat the nest itself. Here’s how 9 options compare:
| Method | Best for | Main drawback |
| Professional extermination | Large or hidden nests and sting allergies | Costs more than DIY |
| Aerosol insecticide | Small, accessible nests | You must approach the nest |
| Insecticidal dust | Underground and wall-void nests | Needs a close approach |
| Diatomaceous earth | Avoiding synthetic insecticides | Slow and weak when wet |
| DIY traps | Fewer foragers around patios | Rarely eliminates the colony |
| Dishwashing detergent | Small nests | Hard to reach the whole colony |
| Liquid insecticide | Accessible ground nests | Higher sting risk |
| Peppermint oil | Deterring yellow jackets before they nest | Not a proven nest treatment |
| Bug smoke bomb | Established underground nests | Harsh chemicals and fire risk |
Option 1: Professional extermination
A licensed pro is the safest way to eliminate yellow jackets, especially for large or hard-to-reach nests and anyone allergic to stings.
Removal averages about $725, the highest of any wasp type, because nests are often hidden underground, according to our nest removal cost guide.
Option 2: Aerosol insecticide
Aerosol insecticides kill on contact. At dusk or dawn, spray into the nest entrance, and repeat if needed.
The sprays can also harm beneficial insects, so aim only at the nest.
Option 3: Insecticidal dust
Kopco says yellow jackets attack the dust and spread it through the nest, often killing the colony within an hour.
Give the entrance 10 to 20 good puffs from a bulb or bellows duster, he says.
James R. Baker, professor emeritus at NC State University in Raleigh, North Carolina, pours about a teaspoon of 5% carbaryl dust into the opening. The next day, workers track through the residue and carry it into the nest, and within a few hours the colony should be dead, he says.
Option 4: Diatomaceous earth
Diatomaceous earth, a natural powder of crushed fossils, works as a contact insecticide, drying insects out and scratching their exoskeletons.
Sprinkle it lightly around and inside the entry hole, and reapply after rain. Avoid breathing the dust.
Option 5: DIY traps
Lure traps set in early spring catch queens before they start new nests. You also can bait homemade traps with fruit juice.
Place traps away from patios. They reduce foragers but rarely eliminate the nest.
Option 6: Dishwashing detergent
After dusk, pour water mixed with plenty of dish detergent into the entrance or spray it with a hose-end sprayer, then leave fast.
Leftover herbicide in a sprayer can damage your lawn. If it does, you can grow grass fast.
Option 7: Liquid insecticide
Sprayed at night onto nests or entry points you can reach, liquid insecticides kill on contact or ingestion.
For wall nests, stick with dust, since water in liquids and foams can damage drywall or create wiring hazards, Kopco says.
Option 8: Peppermint oil
Baker says he knows of no research on peppermint oil and yellow jackets, so it isn’t a proven nest treatment. Kopco adds that essential oils evaporate within minutes, and strong smells may make wasps more defensive during treatment.
Strong scents can affect bees and butterflies, too, says Nicole C.S. Bell, pollinator specialist with UMass Amherst Extension in Amherst, Massachusetts.
Option 9: Bug smoke bomb
A bug smoke bomb (fogger) releases insecticide smoke that forces yellow jackets out of an underground nest. Use it at night and follow the label closely, since foggers carry a fire risk.

Safety considerations when getting rid of yellow jackets
To stay safe, cover up, work at night, and plan your exit.
Wear protective clothing
Cover yourself from head to toe:
Body: Wear coveralls or thick long sleeves and pants.
Hands and feet: Wear sturdy gloves and closed-toe shoes with socks.
Head: Wear a beekeeping veil or a hat with a net.
Work at dawn or dusk
Treat nests after dark or at dawn, when most yellow jackets are inside. As Kopco puts it, “Yellow jackets cannot see in the dark any better than we can.”
He suggests a red light set off to the side. Yellow jackets don’t see red well, and any that fly toward it are drawn away from you.
Keep your distance and stay calm
Plan an escape route, and stay out of the nest’s main flight path, Kopco says. Work from as far away as you can. “Most aerosol cans of wasp and hornet spray have ranges of 15-30 feet,” he says.
Watch the insects. Kopco says calm flight means no alarm, circling the nest signals a threat, and wasps circling you are sizing you up. If they ram you or fly at your face, back off.
Bell says to “avoid swatting or panicking,” since flailing makes you look like a bird, the yellow jacket’s biggest predator.
If you’re stung, back off and wash the spot with soap and water. That removes the alarm pheromone that marks you for more stings, Kopco says.
Consider allergic reactions
About 2 million people in the U.S. have a venom hypersensitivity that can make a sting life-threatening.
If you have a sting allergy, let someone else handle the nest, and carry epinephrine, such as an EpiPen. Seek medical help right away for trouble breathing or swelling.
Skip gasoline, fire, and sealing the entrance
Never use gasoline or fire on a nest. If you treat a nest inside a wall, don’t plug the entrance, or the wasps may end up inside your home.
How to keep yellow jackets out of your yard
The best way to keep yellow jackets out of your yard is to remove the food, water, and shelter that attract them.
Bell puts it this way: “Prevention of establishment is the safest and most ecologically sound method.”
Cover food and drinks: Keep sugary and protein-rich foods covered outdoors and pet food inside.
Maintain clean outdoor spaces: Keep tight lids on trash cans, and rake up fallen fruit.
Fix leaks and trim plants: Repair leaky hoses, and keep grass mowed and shrubs trimmed.
Seal openings and cracks: In spring, fix cracks in siding and fill only the rodent holes near busy spots, since bumblebees use them, Bell says.
Plant strongly scented herbs: Mint and basil near seating areas may help a little.
Skip perfume and bright clothing: Wear plain clothing and no perfume outdoors.
Check for new nests in spring: Kopco says nests start by late May or early June, when a broom or hose can knock them down.
At that stage, the nest may hold only the queen and her brood. As Kopco explains, “The queen is not particularly defensive at this time.”
Yellow jackets also pollinate, prey on pests like caterpillars, and feed native birds, Bell says. For nests along borders or away from busy areas, “learning to co-exist is a valuable skill.”

FAQs
If you can reach an aerial nest from the ground, use a jet-stream spray labeled for wasps or hornets. Aim at the opening at night, and saturate the nest. If you need a ladder, call a pro, since you can’t escape quickly.
Yes, eventually. Nests decline through fall and die by the first frost, Bell says, and old nests aren’t reused the next year. Late in the season, Kopco says, you can usually ignore a nest that’s easy to avoid until winter kills it.
Make sure the nest is empty, then open it to see how the papery cells are built. You can also donate it to a local school’s science class or a nature program at a park, since the wasps won’t move back in.
When to call a pest control pro
For large, hidden, or wall nests, or a sting allergy, call a pro. Licensed exterminators have the gear to get rid of yellow jackets in your yard safely.
Once the nest is gone, Lawn Love’s local bush trimming pros can trim the overgrown shrubs that hide yellow jackets.
