The Main Types of Yellowjackets Found in the US
If a striped wasp has ever dive-bombed your picnic or cookout and refused to leave, you’ve likely met a yellowjacket. They’re fearless, food-obsessed, and quick to sting if you get too close to their nest. This guide breaks down the main types of yellowjackets in the U.S, where they prefer to build nests, and how to get rid of yellowjackets safely (hint: there’s a right way and a very wrong way).

What Yellowjackets Look Like (and Why They Sting So Much)
Yellowjackets are often mistaken for bees, but they’re sleeker, brighter, and much more aggressive around food. They have bold black-and-yellow bands on their bodies, narrow waists, and stingers they can use repeatedly. The workers are about 3/8″–5/8″ long, and the queens are even larger. They are also very territorial—if they think you’ve found their nest, yellowjackets will immediately rally the troops.
The Four Major Yellowjacket Species in the U.S.
German Yellowjacket
An overseas import that has since made itself at home across much of the U.S., the German yellowjacket loves wall voids, attics, and other tucked-away structural spots. They’re persistent scavengers and notorious “indoor” nesters, which is why you’ll see steady traffic in and out of a single crack or soffit.
Eastern Yellowjacket
Common throughout the eastern states, this yellowjacket prefers underground nests like old rodent burrows or pockets in the soil. Colonies can explode into the thousands by late summer, which is also when they’re quickest to sting. If you’re doing yardwork in the Eastern U.S. in August or September, there’s a chance you may accidentally encounter a nest if you’re not careful.
Southern Yellowjacket
Found throughout the southeastern U.S., southern yellowjackets are particularly aggressive. Their colonies often start small but can expand rapidly, especially in warm climates where they can survive year-round. They’ll go underground like their cousins, but in warm regions, they can construct giant above-ground nests that seem to appear overnight. They’re also famously defensive, and in mild winters, some colonies can keep going into the next year.
Western Yellowjacket
The Western yellowjacket is the most significant wasp in the western states. From the West Coast through parts of the interior West, you’ll often find them around outdoor dining, trash areas, and parks. They’re the classic “hover over your plate” species and usually nest underground. You can expect them to show up fast when food is out, especially around meats and sweets.
Where Yellowjackets are Found in the U.S.
You’ll find at least one of these yellowjacket species in nearly every state. Activity begins in the spring and intensifies as the season progresses, with colonies expanding through summer and reaching their peak in late summer/fall. Yes, that’s exactly when you’re grilling, hosting parties, hanging by the pool, and taking out the trash in the heat, so this is why you will encounter them a lot more.
Yellowjacket Nesting Habits and Behavior
- Underground nests: Many species prefer abandoned burrows and tight cavities inside soil.
- Structural hideouts: German yellowjackets especially like wall voids, soffits, attics, and crawl spaces.
- Large above-ground nests: Southern yellowjackets can build large aerial nests in shrubs, sheds, or eaves in warm zones.
No matter the species or where they are nesting, yellowjackets are fiercely protective of their colonies. Disturbing a nest entrance (even by accident with a mower or trimmer) can trigger dozens of stings in seconds.
Are Yellowjackets Dangerous?
Yes. A single sting definitely hurts, but multiple stings can mean swelling, nausea, or worse. Because they can sting repeatedly, encounters with yellowjackets can escalate quickly. Anyone with a wasp allergy is at risk of a severe reaction and should seek medical help immediately if stung. Pets can get into trouble, too—curious dogs sniffing around the yard are frequent targets.
Signs of Yellowjackets
If you notice these warning signs, avoid the area until you can have it inspected:
- Frequent sightings of wasps flying in and out of a single spot in the ground or a wall.
- A buzzing sound near attics, soffits, or underground cavities.
- Increased wasp activity around food sources, garbage bins, or outdoor eating areas.
If you spot a flight path or hear buzzing from inside a void, step away. The nest is probably closer (and bigger) than it looks.
What to Do if You Think You Have Yellowjackets
It’s tempting to try a do-it-yourself approach, but yellowjackets are among the most aggressive stinging insects you’ll encounter. Spraying a nest or trying to dig it out can provoke a swarm that ends with multiple painful stings.
Some common DIY methods for yellowjackets:
Some people choose to try their luck and either spray yellowjacket nests, pour boiling water into underground nests, or cover entrances with dirt or heavy materials. And while these methods can sometimes reduce activity, they will rarely eliminate the entire colony and carry some real risks. Remember, yellowjacket colonies are often larger than expected, with multiple hidden entrances. Disturbing a nest with a DIY fix can quickly lead to dozens of wasps attacking.
The safest, most reliable method for yellowjacket removal is to call a professional. You need a pest control expert with the gear, products, and know-how to treat the entire nest, including hidden combs and extra entrances.
How to Prevent Yellowjackets
You can’t keep every wasp off your property, but you can make your place way less appealing:
- Keep garbage bins tightly sealed and clean of any food residue.
- Avoid leaving sugary drinks, fruit, or meat scraps outside.
- Inspect your yard for burrows or cavities that could serve as nesting sites.
- Seal gaps in siding, soffits, and wall voids.
- Maintain your screens on windows, doors, and vents.
