If you live across the southern or eastern United States, one of the most common wasps you’ll find building a small, umbrella-shaped nest under your porch eave or mailbox is the Guinea wasp. Also called the Guinea paper wasp, this slender brown-and-yellow insect is a familiar backyard resident from Texas and Florida up through the Mid-Atlantic — and its range keeps expanding northward.
For non-aggressive wasps I've had great luck spraying nests with this Spectracide wasp remover in the evening. For a nest up high in an eave, soffit, or tree, this Gotcha pole adapter clamps onto the can so you can spray from the end of an extension pole and treat the nest from 10+ feet away instead of standing right under it. And for anything aggressive I wear this ridiculous-looking upper torso beekeeping suit and keep my distance. It seems silly, but trust me, I learned the hard way.
This guide covers everything homeowners need to know about the Guinea wasp: how to identify it, how it behaves, what its nests look like, its sting risk, and the safest ways to manage it around your home.
The Guinea wasp (Polistes exclamans) is a species of paper wasp native to North America. It belongs to the genus Polistes, the same group that includes the northern paper wasp, the red paper wasp, and the southwestern apache paper wasp. Like all paper wasps, it is a semi-social insect that builds open-celled, papery nests from chewed wood fibers mixed with saliva.
You may also see it called the “common paper wasp” or simply the “Guinea paper wasp.” The name has nothing to do with the country of Guinea or guinea fowl — it is a common name that has stuck to this species over the years. Scientifically, Polistes exclamans is one of the most thoroughly studied paper wasps in North America, largely because its modest colony size and exposed nests make it easy for researchers to observe.
Guinea wasps are members of the family Vespidae, the same family that contains yellow jackets and hornets. But unlike those more aggressive relatives, the Guinea wasp is a relatively docile insect that plays a genuinely beneficial role in gardens and landscapes.
The Guinea wasp is primarily a wasp of the southern and southeastern United States. Its core range stretches across:
It also ranges into Mexico and Central America. Notably, Polistes exclamans has expanded its range significantly northward over recent decades, with established populations now appearing well beyond its historical southern boundaries — a shift many entomologists associate with warming regional climates.
Because its range overlaps heavily with the red paper wasp and other Polistes species, homeowners in the South frequently encounter several kinds of paper wasps on the same property and mistake one for another.
Guinea wasps are medium-sized, slender wasps, typically measuring about 15–17 mm (roughly 0.6–0.7 inch) in length. They share the classic paper wasp silhouette:
This lean, long-legged profile is the easiest way to distinguish any paper wasp from a stockier yellow jacket or hornet.
The Guinea wasp’s coloring is where it gets its distinctive look. The body is generally brown to reddish-brown, marked with yellow bands and spots across the abdomen and thorax. Many individuals also show patches of reddish or ferruginous (rust) coloring.
The single most reliable field mark for the Guinea wasp is its antennae: they are dark at the base but transition to a bright orange or yellowish-orange at the tips. This two-tone antennal coloring is a hallmark of Polistes exclamans and helps separate it from lookalike species when you can get a close, safe view.

Guinea wasps build the signature open, umbrella-shaped nest typical of all Polistes paper wasps. Key features include:
Colonies are relatively small compared with yellow jackets — often housing only a few dozen wasps at their summer peak, rarely reaching the hundreds or thousands seen in yellow jacket nests.
Common nesting sites around homes include:
One interesting behavior of the Guinea wasp is its tendency to build satellite nests — secondary nests started near the main colony. This is thought to be a survival strategy that helps the colony persist if the primary nest is destroyed by predators or bad weather. For a deeper look at nest construction and safe removal, see our paper wasp nest identification and removal guide.
The Guinea wasp is a primitively eusocial insect, meaning colonies have a basic social structure but lack the rigid caste system of honey bees. A typical annual cycle looks like this:
In terms of temperament, Guinea wasps are relatively non-aggressive away from the nest. While foraging on flowers or hunting for caterpillars, they generally ignore people entirely. Defensive stinging behavior is triggered only when the nest itself is threatened — by close approach, vibration, or physical contact.
For most people, the Guinea wasp poses low to moderate risk. Like all paper wasps, females can sting, and unlike honey bees, they can sting more than once because their stinger is not barbed. A sting causes the usual sharp pain, redness, and localized swelling that typically fades within a day or two.
The real concern is for people with insect venom allergies. A small percentage of the population can experience a severe allergic reaction (anaphylaxis) to wasp venom. Signs of a serious reaction include difficulty breathing, swelling of the face or throat, dizziness, or hives spreading across the body. These are medical emergencies — call 911 immediately.
For ordinary stings, basic first aid is usually enough: wash the area, apply a cold compress to reduce swelling, and use an over-the-counter antihistamine or pain reliever as needed. For a complete walkthrough of symptoms and treatment, see our paper wasp sting treatment guide.
Before reaching for the spray, it’s worth understanding what Guinea wasps do for your yard. They are beneficial predators. Adult wasps hunt caterpillars, flies, and other soft-bodied insects, chew them up, and feed them to their developing larvae. A single colony can remove large numbers of garden pests over a summer, making these wasps a natural form of pest control.
Adult Guinea wasps also feed on nectar, and in doing so they provide incidental pollination as they move between flowers. For gardeners and homeowners, a Guinea wasp nest in an out-of-the-way corner is often more helpful than harmful — which is why coexistence is frequently the best choice when the nest isn’t in a high-traffic area.
When a Guinea wasp nest is located somewhere that puts people at risk — beside a doorway, over a walkway, or where allergic household members spend time — removal may be warranted. Follow these safety guidelines:
To keep wasps from returning, inspect eaves and outbuildings in early spring for founding queens and remove small, newly started nests before a colony establishes.
The Guinea wasp (Polistes exclamans) is one of the most common and recognizable paper wasps across the southern and eastern United States — a slender, brown-and-yellow insect with distinctive orange-tipped antennae that builds small, umbrella-shaped nests around homes. While it can sting in defense of its nest, it is a relatively docile and genuinely beneficial insect that helps control garden pests throughout the growing season.
For most homeowners, the smartest approach is informed coexistence: identify the nest, judge whether its location poses a real risk, and remove it only when necessary — safely, at night, and with proper protection.
