A swarm of yellow jackets can put a damper on a picnic or other outdoor plans. And if they invade your yard, or worse, your house, they become a safety hazard. So how do you eliminate yellow jackets?
How to get rid of yellow jackets? To get rid of yellow jackets, you need to know what their nest looks like and where it’s located. Yellow jackets are attracted to protein and sugary foods, so don’t leave them out. If you choose to spray the nest, wear protective clothing, and wait until it’s dark.
Getting rid of yellow jackets starts with understanding what keeps them away. Read on as we discuss where they live, how to find the nests, what to do if you get bitten, and go over ways to kill them.
What Is a Yellow Jacket?
Yellow jackets are carnivorous and social wasps known for their fierce stings, which they use to paralyze their prey or defend their nests. They can be found worldwide. In the United States, they can be found in every state, but yellow jackets are most prevalent in the southeast.
In the spring and early summer, yellow jackets forage for insects to feed the larvae. As they grow older, their diets change, and they seek out sugar at the same time that people are spending more time picnicking.
What Does a Yellow Jacket Look Like?
Although yellow jackets don’t look like honeybees, people sometimes confuse the two. In cartoons, honeybees are usually drawn with yellow and black stripes, which isn’t accurate.
Yellow jackets have yellow and white markings. They have white or yellow hair on their faces, but they aren’t “fuzzy” like bees. Although most yellow jackets are yellow and black, some species have red markings and others are white and black.
Also, since yellow jackets don’t carry pollen, their hind legs aren’t hairy like a bee’s.
How Big Are Yellow Jackets?
Yellow jackets are similar in size to bees, which is one reason people sometimes confuse the two.
Grown yellow jackets are 1/2 in (1.27 cm) long and nearly hairless. Queens are 3/4 in (1.91 cm) long. Yellow jacket worker bees weigh 50 to 60 grams (0.11 to 0.13 pounds) on average, which is half of a worker bee’s weight.
Even though they’re small, yellow jackets can build enormous nests. In the last few years, several nests the size of a car have been spotted in southeastern states with mild winters.
Types of Yellow Jackets
Both yellow jackets and hornets are members of the Vespinae subfamily of wasp species. Although there are 4,000 wasp species in the United States, most are solitary insects that prey on arthropods.
Only several yellow jacket species are considered dangerous. These include the Eastern (Vespula maculifrons), Southern (Vespula squamosa), and Western yellow jackets (Vespula pensylvanica), which are native to the United States, and German yellow jackets (Vespula germanica), which were introduced in the 1970s.
How Long Do Yellow Jackets Live?
A yellow jacket colony dies out in the winter, except for young yellow jacket queens. The young queen survives by finding a shelter location, such as in a decaying tree stump, to hibernate.
In early spring, the queens come out of hibernation and feed on nectar sources, such as flowers, and prey on arthropods. It’s only later when the nest has been built that yellow jackets seek out other food.
Yellow jackets die when temperatures remain under 45 degrees for five to seven days, so they overwinter in their nests in some areas of the country.
What Do Yellow Jackets Eat?
Yellow jackets feed on flower nectar and other sources of sugar for energy. However, their larvae need protein, so yellow jackets hunt insects and other protein sources to take back to their nests. They’ll travel up to a mile from their nests to forage for food.
Since yellow jackets eat insects, they’re sometimes considered beneficial insects. Most homeowners, however, feel the dangers of getting stung outweigh any potential benefits.

Yellow Jacket Nest
The chances are excellent that you’ll spot a yellow jacket before you find its nest. But what do their nests look like, and where can you find them?
What Does a Yellow Jacket Nest Look Like?
A yellow jacket nest is built from wood fibers which the queen chews and mixes with saliva to make a paper-like structure. The queen will build the initial nest, consisting of 25 to 40 small cells surrounded by a smooth, paper-like envelope.
Once the workers emerge, they take over the job of building the nest and foraging for food while the queen remains in the nest and lays eggs.
People sometimes confuse yellow jackets and paper wasp nests. A nest that resembles a honeycomb belongs to paper wasps. Yellow jacket nests typically have a single opening and resemble an oddly shaped paper mache project.
Where Do Yellow Jackets Nest?
Yellow jackets prefer to nest underground, usually in holes dug by small rodents such as squirrels, moles, or groundhogs. Not only do they not have to dig a nest, but they’ll find insects to feed on.
If they cannot find underground nests, they’ll look for trees and hollow logs. They’ll also build nests in attics, on eaves, or if there’s easy access, inside house walls.
How To Find a Yellow Jacket Nest?
Spotting a yellow jacket nest can be difficult, especially if they’ve built it underground, in dense shrubbery, or inside an attic or house walls. In addition, yellow jackets could’ve built several nests in an area, or a nest can be several hundred feet (30.48 m) away.
To find a yellow jacket nest, let the yellow jackets guide you to it, and use these tips to help you locate a nest:
- Look for them on a sunny day, preferably in the middle of the day. The late afternoon might help you spot them flying in a straight line to their nest.
- Yellow jacket nests are often underground, so be careful where you step.
- You could come across a group of yellow jackets guarding a nest opening.
- Yellow jackets often build more than one nest, so if you spot one, continue searching for others.
- Use protein or sugary foods as bait and follow them to their nest (or nests).
Are Yellow Jackets Dangerous?
Yellow jackets are dangerous insects known for defending their nests much more actively than paper wasps and honeybees. A swarm of yellow jackets is a sign they feel their nest is being threatened. But yellow jackets often sting for no reason, even if they haven’t been disturbed. And once one stings you, others are not far behind.
Are Yellow Jackets Aggressive?
Yellow jackets are aggressive because they’re social animals that work together for a common cause. Once a single insect feels the nest is being threatened, the entire colony gets ready to attack. Among insects, they’re some of the most strongly social, so you won’t have one or two yellow jackets out to get you but the whole nest.
Do Yellow Jackets Sting?
Honeybees lose their stingers when they attack, but yellow jackets have smooth stingers and can sting repeatedly. However, they inject less venom in the second sting.
The poison in a yellow jacket’s sting can cause immediate pain followed by inflammation or redness, which can last for several hours. Some people experience warmth and itching.
Not only that, yellow jackets bite your skin to get a better grip before they sink their stingers in, which is another reason their bites are painful.
What Does a Yellow Jacket Sting Look Like?
The area around the sting will swell and turn red. The area can also become quite itchy. Massive swelling is a serious sign that requires urgent medical care.
Occasionally a yellow jacket sting can become infected. If there are red streaks, pus, or the swelling doesn’t reduce within a few days, you should have a doctor take a look at it.
Do Yellow Jackets Die After They Sting?
Yellow jackets don’t die after they sting. Their stingers aren’t jagged, so it remains attached when they pull it out. When the honeybee loses its stinger, it loses not only the stinger but enough of its digestive tract to kill it.
Allergic Reaction to Yellow Jacket Sting
Some people have allergic reactions to yellow jacket stings. The following symptoms require medical attention:
- Breathing difficulties, coughing or wheezing, or difficulty swallowing
- Vomiting or diarrhea
- Feeling dizzy or lightheaded
Call 911 if these symptoms occur. Additionally, help those experiencing the above symptoms lie on their back, raise their feet, and cover them with a blanket.
You should also seek medical help if you’ve been stung in the mouth or throat or been stung more than 10 times.
What Attracts Yellow Jackets?
Sugary foods and drinks attract yellow jackets. In the wild, they get sugar from nectar and protein from arthropods. So, if humans leave sweet treats out, they come to scavenge. This is why they can often be found at picnic facilities, especially those with open garbage cans.
Even if you keep sugary food and drinks inside and always keep your trash cans securely closed, yellow jackets might still show up in your yard. They’ll be attracted to yards with overripe fruit, hummingbird feeders, or pet food kept outside, along with the centipedes and beetles in the ground.
Yellow jackets are also attracted to bright colors and floral perfumes, so if you have a yellow jacket problem, wear plain clothes and avoid perfumes until they’re gone.
Finally, if you kill a yellow jacket, don’t be surprised if others show up because as it dies, it releases pheromones that alert other colony members.
How To Kill Yellow Jackets? Step by Step Instructions
To kill yellow jackets, you need to do the following:
1. Determine where they’re coming from.
2. Decide whether you want to get rid of them.
3. Come up with a plan for how to keep them from returning.
Since many of the instructions are location-specific, the rest of the guide will help you tackle different situations. You’ll also get a few recommendations for products that might help you get rid of the aggressive yellow jackets.
Getting Rid of Yellow Jackets and Their Nests in Some Specific Places
The best way to get rid of yellow jackets and their nests depends on where they are. Strategies for killing them vary from what to do with the nests to how to deal with individual yellow jackets in the house. The following sections will give instructions and guidelines for dealing with the problem in different situations.
How To Get Rid of Yellow Jacket Nest?
Killing individual yellow jackets won’t solve a yellow jacket problem. But once you locate the yellow jacket nest, you can go about getting rid of them.
To get rid of yellow jackets nest, follow these steps:
1. Put on protective clothing, such as long sleeves and gloves, as the chances of getting bitten are greater. To avoid having yellow jackets fly under your clothes, tape the sleeves to your skin. In addition, wear a hat and face veil.
2. Use a wasp and hornet spray that is labeled either “quick knockdown” or “quick freeze.”
3. Begin spraying in a fanning motion as you approach the nest.
4. As you get closer, spray directly into the nest’s entrance.
5. Check for activity the next day and reapply if needed.
How To Get Rid of Yellow Jackets in the Ground?
To get rid of yellow jackets in the ground, follow these steps:
1. Use a yellow jacket control aerosol product that contains pyrethrum. The pyrethrum creates a gas that fills the nest and kills the yellow jackets.
2. Wait until sundown so that the foragers have reentered the nest. Avoid shining a light in the nest as that might cause yellow jackets to fly out.
3. Yellow jackets cannot see red, so if you must use a flashlight, cover it with red cellophane.
4. Apply an insecticide.
5. Check the nest the following day. If yellow jacket activity is still present, spray again and top with insecticide dust.
Keep an eye on the nest for a few days. Yellow jackets deep in the nest will survive, and the nest can become active again.
How To Get Rid of Yellow Jackets in Siding?
Once yellow jackets find their way into your house’s siding, they’ll look for a place to build a nest. So it’s essential to get the yellow jackets out before they do more damage.
1. Locate where they are entering the siding.
2. Mark off the entrance holes.
3. Use insect dust, such as Bayer Delta Dust, which they’ll carry with them as they return to their nest, thereby killing the other yellow jackets.
No products found.
4. You’ll need an applicator to spread the dust. An empty squeezable bottle with a tip works, or you can purchase a kit that includes the dust and applicator.
A one-time application probably won’t do the trick, so you’ll want to check the entrances two to three days later. Multiple applications may be necessary depending on the size of a nearby nest.
If you choose to use a spray wasp killer, you should locate the entrance, spray it once the yellow jackets are inside, and then plug the entrance so they can’t escape.
How To Get Rid of Yellow Jackets in a Wall?
Once yellow jackets have gotten into your walls, you have a more serious problem. Again, you can kill them using similar techniques as siding, except you’ll have to find out in which cavities they have built their nests.
Once you’ve killed them, you have another problem – what to do with the nest. Decomposing wasps can invite scavengers like ants. If yellow jackets got into your walls, you know small insects can find their way.
Even if you locate the hole they use to enter and exiting, their nest might not be anywhere near the opening. To get rid of yellow jackets in your wall, consider consulting with an exterminator for advice.
How To Get Rid of Yellow Jackets in House?
A yellow jacket in the house is more than a mere nuisance. But how do you kill one without having it go after you? Doing so starts with several don’ts.
1. Don’t panic and make sudden moves. A startled yellow jacket is likely to stop searching for either food or a way out and defend itself. If you must move, do so slowly.
2. Don’t antagonize it. If you spray it with an insecticide or swat at it and miss, you’ll have made at least one enemy.
3. Don’t take away the food or drink that has caught its attention. Instead, remove any nearby food and beverages.
You should try the following:
1. If it’s an alone yellow jacket, open a window or door and let it find its way out. Remember that they are especially social animals, and most yellow jackets would prefer to be with other yellow jackets instead of being trapped and alone.
2. Lure it into a trap with food. Put food or drink inside a resealable jar or soda bottle and wait for the yellow jacket to land. Then, seal the jar and either throw it away or release the yellow jacket away from your house.
Whatever you do, don’t panic.
How To Get Rid of Yellow Jackets Around the Pool?
No one will have a good time if you don’t get rid of yellow jackets around your pool. They’ll be attracted by the food and drink available. But even if you clean up thoroughly, they’re attracted to the water source, and there’s not much you can do about that, short of draining it.
To get rid of yellow jackets around the pool, you can try the following:
- Make the place something they’ll avoid. Yellow jackets dislike spearmint and thyme, but they really hate wormwood. If they show up every year, consider planting one or both. Just remember that wormwood is extremely poisonous and shouldn’t be consumed. A less permanent solution is cucumber slices covered with aluminum. The reaction gives off a chemical odor yellow jackets don’t like.
- Fool them. Some pool owners have success with using fake nests away from the pool. As a last resort, you can place raw meat away from the pool. However, this is a temporary solution at best since the meat will also attract other insects as well as vermin.
- Trap them. Use traps, either commercial or DIY. If yellow jackets are an annual problem by the pool, combine the traps and some plants to keep them away and kill any that don’t have enough sense to ignore the warnings.
How To Get Rid of Yellow Jackets in the Attic?
Although active DIYers can eliminate yellow jackets in the attic, doing so carries risks.
To get rid of yellow jackets in the attic, here are some methods you can try.
- Use a bee trap. Bee traps contain a sweet, sugary liquid that attracts bees, wasps, and yellow jackets. Once they enter the trap, they drown. The problem with bee traps is that they might bring additional yellow jackets into the attic.
- Use repellents. Repellents can keep them away from you or your children temporarily, but they won’t chase them away permanently. And they could decide to swarm, which you don’t want, especially in an enclosed space.
- Use chemicals. Chemical eradication usually involves removing the nest. Once you locate the nest, you’ll need to clear the area around the nest, secure windows and vents to keep the spray in the attic and spray the nest. Bomb-style poisons work well against nests on the floor, but use sprays with projectile shots for hanging nests.
You’ll need to wear protective clothing while trying to get them out of the attic. Depending on the size of your attic and the nest, consider talking with a professional exterminator.
How To Get Rid of Yellow Jackets Naturally?
Along with planting herbs like thyme, spearmint, and lemongrass or planting wormwood, try hanging scented dryer sheets near your patio.
Additionally, consider creating a decoy. Yellow jackets are territorial, so if they see a nest that isn’t theirs, they’ll steer clear of it. These Patio Eden Wasp Nest Decoys from Amazon are realistic-looking enough to fool yellow jackets. You can use a brown paper bag to create a DIY version, but neither is waterproof. So an application of clear acrylic spray will help them resist the elements.

How To Keep Yellow Jackets Away?
To keep yellow jackets away is a matter of thinking about what attracts them and eliminating that. Here are some tips to keep them from coming to visit:
- Throw away leftover food and keep trash cans tightly sealed.
- The honeydew from aphids is an excellent source of sugar, so if you have an aphid infestation in your yard, you need to control it.
- Leaky faucets and hoses can provide yellow jackets with water, so repair those.
- Avoid brightly colored clothes and perfumes when outside.
How To Make a Yellow Jacket Trap?
To make a simple DIY yellow jacket trap, you need a plastic soda bottle, a sweet liquid, dish soap, and a pair of scissors or knife to cut the soda bottle.
1. Remove the cap – you won’t be needing it.
2. Cut off the top fourth of the bottle. It needs to stay in one piece because you’ll use it as a funnel of sorts.
3. Pour enough sweet liquid – sugar water, juice, or soda – to fill half the bottle.
4. Add a few drops of dish soap and mix.
5. Invert the top of the soda bottle and place it on top, like a funnel. If there are gaps or it doesn’t seem secure, tape it down.
The yellow jackets will be attracted to the sugary water but will struggle to get out. Eventually, they’ll drown.

The good news about yellow jackets is they die off in the winter, but the bad news is they can cause you trouble until then.
Try to avoid leaving foods that’ll tempt them to your house. If they’re mainly foraging for food in the surrounding area, consider whether you want to take a chance destroying their nests. If you really need to, make sure to dress appropriately and wait until dusk before spraying the nest.
