Yes, red paper wasps can and do sting. They use their stingers to defend their nests and will sting when they feel threatened. The good news is that they’re not particularly aggressive insects. Unlike yellowjackets, which may sting unprovoked around food, red paper wasps typically leave you alone unless you get too close to their nest or accidentally disturb one.
When Red Paper Wasps Sting
Red paper wasps are social insects that build open, papery nests in sheltered spots: under eaves, at the corners of windows, beneath decks, inside vent louvers, and on uncapped fence poles. Chain link fence caps are another common nesting site. The wasps post guards near the nest entrance, and those guards use chemical signals to alert the rest of the colony when something gets too close. Once triggered, wasps can swarm out of the nest quickly.
The most common scenario is someone walking near a nest they didn’t notice. Vibrations from a lawnmower, a ladder bumping against an eave, or a hand reaching into a mailbox can all set off a defensive response. Outside of nest defense, red paper wasps are docile. A single wasp foraging on flowers or hunting caterpillars in your garden is unlikely to sting you unless you swat at it or pin it against your skin.
They Can Sting More Than Once
Unlike honeybees, paper wasps don’t leave their stinger behind in your skin. Their stinger is smooth rather than barbed, so they can pull it out and sting again. This means a single wasp defending its nest can deliver multiple stings, and if the colony is large, several wasps may sting at once. If you find yourself near an active nest and wasps begin flying toward you, walk away quickly rather than swatting, which only increases the threat signal.
How the Sting Feels
Paper wasp stings land at roughly 1.5 on the Schmidt Sting Pain Index, a four-point scale developed by entomologist Justin Schmidt to rank insect sting pain. That puts them in the lower-middle range, less painful than a yellowjacket sting and well below a tarantula hawk or bullet ant. Schmidt described the sensation of a related paper wasp species as “burning, throbbing and lonely,” comparing it to a single drop of superheated frying oil landing on your arm.
For most people, a sting produces immediate sharp pain followed by redness, swelling, and warmth around the sting site. These local symptoms typically peak within the first hour or two and gradually fade over one to several days. Some people develop a larger local reaction where swelling extends several inches from the sting site over 24 to 48 hours. This is uncomfortable but not the same as a systemic allergic reaction.
Normal Reaction vs. Allergic Emergency
A sting that stays red, swollen, and sore near the sting site is a normal immune response. What’s not normal is symptoms that show up away from the sting. Hives spreading across your body, swelling of the face or throat, difficulty breathing, dizziness, a rapid drop in blood pressure, or nausea and vomiting after a sting are signs of anaphylaxis, a severe allergic reaction that requires emergency treatment. This affects a small percentage of people, but the risk increases with repeated stings over a lifetime because the immune system can become sensitized to wasp venom.
If you’ve had a systemic reaction to any wasp or bee sting in the past, carrying an epinephrine auto-injector is the standard precaution. People stung for the first time who only experience localized pain and swelling can generally manage at home.
Treating a Sting at Home
Because paper wasps don’t leave a stinger behind, there’s nothing to scrape or pull out of the skin. Wash the area with soap and water, then apply a cold pack to reduce swelling. An over-the-counter antihistamine can help with itching, and ibuprofen or acetaminophen can take the edge off the pain. Keeping the area clean and avoiding scratching reduces the chance of a secondary infection. Most stings resolve fully within a few days without any medical intervention.
How to Identify a Red Paper Wasp
Red paper wasps (Polistes carolina) are among the largest paper wasps in the eastern United States. They’re distinguished by their uniformly reddish-brown body and darker, often blackish wings. Their body shape is the classic paper wasp silhouette: slender, with a narrow “waist” between the thorax and abdomen, and long legs that dangle visibly during flight. This separates them from yellowjackets, which are stockier, and mud daubers, which are thinner and solitary.
Their nests are also distinctive. Paper wasps build open-faced, umbrella-shaped nests made of chewed wood fibers. You can see the individual hexagonal cells from below, with no papery outer shell enclosing them. This is the easiest way to confirm you’re dealing with paper wasps rather than yellowjackets or hornets, which build enclosed nests. If the nest looks like a small, upside-down umbrella attached by a single stalk, it belongs to paper wasps.
Reducing Your Risk of Getting Stung
Most stings happen because someone unknowingly gets within a few feet of a nest. Checking under eaves, porch ceilings, and deck railings in early spring can catch nests while they’re still small, sometimes just a queen and a handful of cells. At that stage, they’re easy to knock down at night when the wasp is less active. By midsummer, colonies can grow to dozens of workers, and removal becomes riskier.
When working outdoors near structures, look before you reach into sheltered spaces. Avoid wearing strong fragrances, which can attract foraging wasps. If a wasp lands on you, stay still and let it fly away on its own. Swatting releases alarm chemicals that can recruit more wasps to sting. Red paper wasps are genuinely beneficial insects that consume large numbers of caterpillars and other garden pests, so leaving nests alone in low-traffic areas is often the simplest approach.
