Paper wasp nests can be safely removed by most homeowners using an aerosol wasp spray applied at dusk or early morning, when the wasps are least active and all inside the nest. The key is timing, protective clothing, and knowing when a nest is better left to a professional. Here’s how to handle it step by step.
Make Sure It’s Actually a Paper Wasp Nest
Paper wasp nests look like a small, open umbrella: a single layer of downward-facing cells with no outer shell covering them. They’re typically gray or brown, roughly the size of a fist to a softball, and attached to a surface by a thin stalk. You’ll find them under eaves, porch ceilings, deck railings, beams, and tree limbs. The European paper wasp also nests inside small cavities like hollow furniture posts, outdoor light fixtures, and grill covers.
This matters because yellowjacket nests look very different and require a different approach. Yellowjackets build enclosed, layered nests with a papery outer shell, often underground in old rodent burrows or inside wall voids. If you see wasps coming and going from a hole in the ground or a gap in your siding, that’s not a paper wasp situation, and DIY removal gets significantly more dangerous.
When to Remove (and When to Wait)
The best time of year depends on where you live. Nest construction starts in late spring and grows throughout summer. By late summer and early fall, colonies produce new queens and the workers become highly defensive of the nest. If you can tolerate the nest and it’s in a low-traffic area, the simplest option is to wait until after the first hard frost. Paper wasps abandon their nests in fall, and they never reuse the same nest the following year. Once the cold kills off the remaining workers, you can knock the empty nest down without any risk.
If the nest is near a doorway, play area, or somewhere people regularly pass, waiting isn’t practical. In that case, early morning is the best time to treat. Wasps are sluggish in cool temperatures and nearly all of them will be inside the nest. Evening and dusk also work well. Avoid midday, when foraging wasps are away from the nest (meaning you won’t kill them) and the remaining wasps are most alert.
What to Wear
Paper wasps can sting multiple times, and they will if they feel threatened. Full skin coverage is non-negotiable. At minimum, wear long pants, a long-sleeved shirt, closed-toe shoes, socks pulled over your pant cuffs, and thick gloves. Tuck your shirt into your pants and secure any gaps at your wrists and ankles. Wasps will find openings.
For better protection, layer up. A thick outer layer of canvas, heavy cotton, or a dense synthetic like a polyester blend makes it much harder for a stinger to reach your skin. Protect your face and head with a hat, safety glasses or goggles, and a bandana or neck gaiter. If you’re dealing with a larger nest or have any history of sting reactions, a full beekeeper-style suit with an integrated hood and veil is worth the investment. Look for suits with elastic cuffs on the sleeves and legs to seal out wasps.
How to Remove the Nest
The standard approach uses a pressurized aerosol wasp and hornet spray, which most hardware stores carry. These sprays shoot a concentrated stream up to 15 to 20 feet, letting you keep your distance. Stand as far back as the spray will reach, position yourself so the wind is at your back, and aim at the nest entrance (the open bottom of the comb). Spray for six to eight seconds, thoroughly drenching the nest. Wasps that fly out will contact the spray as they leave.
Spray at an angle rather than standing directly below the nest. Wasps that drop off the nest will fall straight down, and you don’t want to be standing there. After spraying, leave the area immediately and give it at least 24 hours before approaching again. When you return, check for any surviving wasps. If you see activity, repeat the treatment. Once the nest is dead, knock it down with a long stick or scrape it off with a putty knife and dispose of it in a sealed bag.
A cheaper alternative to commercial sprays is a simple soapy water solution in a spray bottle or garden sprayer. Dish soap clogs the wasps’ breathing pores and kills them on contact. The downside is range: a spray bottle only reaches a few feet, putting you much closer to the nest. This method works best for very small nests (a few cells with only a handful of wasps) in an accessible spot where you can spray and retreat quickly.
When to Call a Professional
Some situations aren’t worth the risk of doing yourself. If the nest is high up on a roofline or requires a ladder, the combination of angry wasps and unstable footing creates a serious fall hazard. Nests inside wall voids, attic spaces, or crawl spaces are also better left to a professional, since these locations make it hard to see the nest, spray accurately, and escape quickly.
Larger nests with dozens of wasps are more dangerous simply because more wasps means more stings if something goes wrong. The same goes for multiple nests clustered near each other. And if anyone in your household has a known allergy to wasp stings, hiring a professional is the safer call regardless of nest size. Removal costs vary based on location, accessibility, and the size of the infestation, but most pest control companies will provide a quote after inspecting the nest.
What to Do if You Get Stung
Paper wasps usually don’t leave a stinger behind, but if one does get lodged in your skin, scrape it out with the edge of a credit card or butter knife rather than pinching it with your fingers (squeezing can push more venom in). Wash the area with soap and water, apply ice to reduce swelling, and take an over-the-counter antihistamine or pain reliever if needed. Hydrocortisone cream or calamine lotion can help with itching.
A normal sting reaction means localized pain, redness, and swelling that peaks within a day or two and fades over the next several days. What’s not normal: hives or a rash spreading away from the sting site, swelling around your mouth or throat, difficulty breathing or swallowing, dizziness, nausea, vomiting, or a rapid or weak pulse. These are signs of anaphylaxis, and they require an immediate call to 911. Stings on or around the eyes, face, or neck also warrant prompt medical attention even without allergic symptoms.
Preventing New Nests
Once you’ve removed a nest, paper wasps won’t reuse it, but they may build a new one in the same sheltered spot. To discourage rebuilding, apply a residual insecticide spray around the area. Treat the foundation of your home, window frames, door frames, eaves, soffits, and rain gutters. These barrier sprays typically last up to 90 days before needing reapplication. Keep people and pets away from treated surfaces for two to four hours after spraying.
Beyond chemical barriers, reduce what attracts wasps in the first place. Open trash cans, fallen fruit, sugary drinks left outside, and pet food all draw foraging wasps. Seal gaps in siding, fill hollow posts on outdoor furniture, and cap open pipes or vents where wasps might nest inside cavities.
You may have seen decoy nests sold online, usually brown paper bags stuffed with newspaper, meant to mimic a rival colony’s nest and scare paper wasps away. Penn State Extension notes there’s no clear evidence these actually work, and plenty of anecdotal reports describe real nests being built right next to decoys. Save your money for a can of spray and some caulk.
