For non aggressive wasps I've had great luck spraying the nests with this Spectracide wasp remover in the evening. For more aggressive wasps I also use this rediculous looking upper torso Beekeeping suit. It seems silly, but trust me, it's amazing.
If you’ve spotted a slender, reddish-brown wasp building a papery nest under your eave or deck railing, you’ve likely encountered a red paper wasp. These striking insects are among the most frequently misidentified wasps in North America, often confused with yellow jackets or hornets despite looking quite different up close. This guide covers everything homeowners need to know about red paper wasps — from accurate identification to safe nest management.
Red paper wasps are social wasps belonging to the genus Polistes within the family Vespidae. The term “red paper wasp” most commonly refers to Polistes carolina, one of the largest and most recognizable paper wasp species in the eastern United States. A closely related species, Polistes perplexus, is also sometimes called a red paper wasp and shares nearly identical habits and appearance.
Like all paper wasps, these species earn their name from the distinctive papery nests they construct by chewing wood fibers and mixing the material with saliva. The result is a gray, paper-like pulp they mold into open, umbrella-shaped combs — a characteristic nest shape that sets paper wasps apart from the enclosed ball-shaped nests of hornets or the underground colonies of yellow jackets.
Red paper wasps are semi-social insects, meaning they form small colonies (usually fewer than 75 individuals) centered around a single fertilized queen. This modest colony size and relatively docile temperament make them considerably less threatening than yellow jackets or bald-faced hornets, though their sting still demands respect.
Accurate identification is the most important first step before deciding how to respond to any wasp near your home.
Polistes carolina is one of the largest paper wasp species you’ll encounter in the US:
| Feature | Red Paper Wasp | Yellow Jacket | Bald-Faced Hornet | Mud Dauber |
|---|---|---|---|---|
| Color | Reddish-brown | Yellow & black | Black & white | Black (often with yellow) |
| Size | 0.75–1.25 in | 0.5–0.75 in | 0.75–1 in | 1–1.25 in |
| Nest | Open umbrella comb | Enclosed paper ball or underground | Large enclosed paper ball | Mud tubes |
| Leg posture in flight | Legs dangle | Legs tucked | Legs tucked | Legs dangle |
| Aggression | Moderate | High | High | Very low |
Red paper wasps are often confused with red wasps generally — but among paper wasp species, their uniform reddish color and large size make them fairly distinctive once you know what to look for.
Polistes carolina is native to the eastern and southeastern United States. Their range spans from southern New England down through the Mid-Atlantic states and across the entire Southeast, extending west into Texas, Oklahoma, and Kansas. They are especially abundant in states like Georgia, Florida, Mississippi, Alabama, and the Carolinas.
You’re most likely to find red paper wasps in:
Red paper wasps prefer warm, sheltered locations for nesting. Common nest sites on residential properties include porch ceilings, deck railings, window frames, garage rafters, fence posts, tree branches, and the undersides of outdoor furniture.
Understanding the paper wasp life cycle helps homeowners know when nests are growing, when colonies are at peak size, and when the problem resolves on its own.
Each spring, a mated queen that overwintered in a protected location (under bark, in wall voids, or leaf litter) emerges and begins constructing a small foundational nest. She lays the first eggs herself and raises the first cohort of workers without assistance.
This early-season period — typically April through May in most of the red paper wasp’s range — is when nests are smallest and easiest to manage. A foundational nest may contain only a single queen and a handful of cells.
As the first worker wasps emerge in late May and June, they take over nest expansion and foraging while the queen focuses on egg-laying. The colony grows steadily throughout summer, reaching peak population in July and August. Mature colonies typically contain 30 to 75 wasps, though larger nests occasionally develop.
This is the period when red paper wasps are most visible around homes. Workers forage actively during daylight hours, hunting insects and collecting water and plant fibers.
By late August and September, the queen begins producing reproductives — new queens and male drones — rather than sterile workers. These reproductive wasps mate, and the newly fertilized queens disperse to find overwintering sites.
As temperatures drop in autumn, the original colony queen, workers, and males all die. The nest is abandoned and not reused. By November or December in most regions, no living wasps remain in the nest.
This natural cycle means that if you have a red paper wasp nest in a low-risk location, waiting until late fall to remove it may be your safest option. By that point, the colony has died out on its own, the nest can be knocked down safely, and no chemical treatment is needed.
Red paper wasps are capable of stinging and will do so if they feel their nest is threatened. However, their temperament is generally calmer than yellow jackets or hornets.
Red paper wasps rarely sting when away from their nest. A foraging wasp flying past you, visiting a flower, or hunting insects is not a threat. Stinging behavior is almost entirely defensive and concentrated around the nest.
High-risk scenarios include:
If wasps emerge from a nest and begin flying toward you, move away slowly and steadily. Running or swatting tends to provoke more stings.
Red paper wasps are valuable predators in the garden ecosystem. Their colony’s protein needs are met almost entirely through hunting — and their preferred prey includes many of the insects homeowners consider pests.
Primary prey includes:
A single active paper wasp nest can eliminate thousands of caterpillars over the course of a summer. Gardeners and farmers sometimes intentionally tolerate or encourage paper wasp nesting in areas away from foot traffic for exactly this reason.
Red paper wasps also contribute to pollination in a secondary capacity. While not efficient pollinators like bees, they do visit flowers for nectar and inadvertently transfer pollen in the process.
The decision to remove or tolerate a red paper wasp nest depends on nest location, proximity to foot traffic, and whether anyone in the household has a venom allergy.
Nests in low-traffic areas — high up in trees, along back fence lines, or in rarely-used sheds — generally pose little risk and provide meaningful pest control benefits. Consider leaving these alone and simply warning family members about their location.
If a nest is in a high-risk location (near doorways, playground equipment, or frequently used outdoor areas), removal may be appropriate. Follow these guidelines:
Best timing: Treat nests at dusk or dawn, when wasps are least active and most individuals are inside the nest. Never attempt removal in the middle of a warm, sunny afternoon.
Protective clothing: Wear thick long-sleeved clothing, gloves, and a hat. A bee veil or face shield significantly reduces risk if you have one available.
Insecticide sprays: Aerosol wasp and hornet sprays designed for nest treatment can be effective. Choose a product with a long-range jet spray so you can treat from 10–15 feet away. Apply directly into the nest opening, then retreat quickly. Wait at least 24 hours before removing the nest.
Never use water alone: Spraying water on a red paper wasp nest will agitate the colony without killing them — this is one of the most common mistakes homeowners make.
Remove after treatment: Once you’re confident the colony is dead (no movement for 24–48 hours), knock the nest down into a sealed plastic bag and dispose of it. Dead nests left in place do not attract new colonies, but removing them eliminates the temptation for overwintering queens to start new nests in the same location next spring.
Reduce the chance of red paper wasps nesting near your home by:
Hire a licensed pest control professional if:
Professionals have access to more effective products, protective equipment, and the experience to handle nests in difficult locations safely.
Homeowners sometimes encounter other reddish wasps that are not Polistes carolina. Here are the most common look-alikes:
Red velvet ant (Dasymutilla occidentalis): Despite the name, this is actually a wingless wasp, not an ant. The female is bright red and black and is sometimes called a “cow killer.” She is solitary (no colony) and her sting is famously intense. She does not build nests in or on structures.
European paper wasp (Polistes dominula): More yellow and black than red, but some individuals lean toward a reddish-orange. Smaller than Polistes carolina, and the most common paper wasp in northern US states.
Cicada killer wasps: Large (up to 2 inches), but predominantly black with yellow markings, not red. Solitary ground-nesters.
If you’re unsure what species you’re dealing with, photograph the wasp from a safe distance and consult your local university extension service, which can provide free identification assistance.
