Spring queen establishment
March through May
Overwintered queens emerge from sheltered cavities and build a small founding nest with a few cells. The queen forages alone and tends the first brood until the first workers emerge.
Local pest control help is one call away.
Red wasps (Polistes carolina and Polistes perplexus) are the largest paper wasps in the southeastern United States. Workers run 25 to 35 millimeters long, more than an inch, with reddish-brown bodies, dark smoky wings, and long legs that dangle in flight. They are noticeably bigger and longer than the northern paper wasps most homeowners are used to seeing, and their nests can grow to 12 to 15 inches across with 200 or more cells.
If you are seeing inch-long rust-colored wasps with dark wings building open umbrella-shaped paper nests under your eaves, on attic peaks, behind soffit panels, or under deck railings, you have red wasps. They are more defensive than northern paper wasps and will attack from 8 to 12 feet away from the nest rather than the usual 3 to 6 feet. Pro treatment is the recommended path for any established red wasp nest. This guide covers identification, where they build, what makes them different, and what professional removal involves.

Red wasps build open umbrella-shaped paper nests in protected outdoor spots with overhead cover. In the southeastern US, the highest-risk zones get hours of sun on southern and western exposures and stay sheltered from rain. Walk these zones in daylight from at least 30 feet back and look up:
Red wasp colonies in the deep south can reach 100 to 300 wasps in a mature nest, and nest envelopes commonly exceed the size of a dinner plate by late summer. If you find an active red wasp nest above an eave, in an attic void, or near a walkway, do not approach within 12 feet. The defense zone is wider than what you might expect from smaller northern paper wasps.
Red wasps are a southeastern US species. Their range covers Florida, Texas, Louisiana, Mississippi, Alabama, Georgia, the Carolinas, Tennessee, and Arkansas. The warm climate supports a larger colony scale than what northern paper wasps reach, and a typical southern home offers everything an overwintered queen needs to start a new nest in spring.
What attracts red wasps:
Red wasps follow an annual cycle in the northern part of their range and stay active year-round in the deep south. Queens overwinter in protected spots, tree cavities, attic corners, fence-post hollows, and emerge in spring to start the cycle again. Sealing those cavities during cold months and removing prior nest attachment points after each season is how you keep the same eave from being colonized year after year.
Find your scenario below. Each row reflects how a red wasp colony actually progresses through a southern season, not a generic wasp timeline.
| What You're Seeing | Severity | If Untreated | Next Step |
|---|---|---|---|
| Small early-season nest in a distant eave or unused yard corner | Early | Red wasp nests grow faster and reach larger size than northern paper wasps; expect heavy expansion through summer. | Schedule a pro this week. Catching the nest before it scales into the hundreds keeps the removal simpler and safer. |
| Mature nest near a walkway, entry door, or patio area | Moderate | Defense zone extends 8 to 12 feet from the nest; foot traffic within that range will trigger attacks. | Schedule evening pro treatment within 48 to 72 hours. Keep family and pets at least 15 feet away in the meantime. |
| Multiple nests on the property plus a nest in an attic void | High | Heavy local population indicates strong overwintering habitat and high likelihood of repeat colonization next season. | Same-week pro visit. Treatment scope should include void treatment for attic nests and a comprehensive seal of overwintering cavities. |
| Sting incident with allergic family member, active nest still in a family area | Urgent | Active medical risk from a larger, more painful sting and broader defense zone than smaller paper wasps. | Same-day medical attention for the sting victim. Emergency pro removal of the nest the same day. |
Red wasp colonies grow faster than smaller paper wasps. If you're between two rows, treat the higher one as your situation.
Red wasps run an annual cycle in the northern part of their range and stay active year-round in the deep south. Either way, the founding queen builds the parent nest alone in spring, workers expand it through summer, and the colony peaks in late summer or fall at 100 to 300 wasps. Only mated queens survive winter.
March through May
Overwintered queens emerge from sheltered cavities and build a small founding nest with a few cells. The queen forages alone and tends the first brood until the first workers emerge.
June through August
Workers expand the paper envelope and brood comb aggressively. Red wasp colonies scale faster than northern paper wasps and commonly reach 100 to 300 workers by late summer in the deep south.
September through October
Nests reach maximum size, sometimes 12 to 15 inches across with 200 or more cells. Reproductive queens and males are produced, and defense behavior intensifies as resources tighten.
First freeze
In the northern part of the range, workers and the founding queen die at the first hard freeze and new mated queens disperse to overwinter. In the deep south, colonies stay active year-round with reduced winter activity.
Annual colonies die in the northern range, but the nest sites stay attractive to next spring's queens. Sealing the eave, soffit, or vent and treating the attachment point after removal is what keeps the same location from being colonized year after year.
Red wasps in the southeastern US run a longer active season than northern paper wasps, with peak aggression in fall. Knowing the seasonal pattern tells you when nests grow fastest and when treatment lands with the most impact.
Overwintered queens emerge and build small founding nests with a few visible cells. This is the best window to schedule a pro before colonies scale, founding nests are smaller and easier to treat with a lower defense response.
Colony expansion accelerates and nests grow well beyond what northern paper wasps reach. Workers forage actively all day, and nests near patios and entries become a daily hazard.
Peak colony size and peak aggression. Defense behavior intensifies as resources tighten and reproductive queens emerge. This is the most dangerous quarter for sting incidents.
In the northern part of the range, colonies die at first freeze and new queens overwinter in protected cavities. In Florida, the Gulf Coast, and south Texas, colonies stay active year-round with reduced winter activity.
Red wasps are larger and more defensive than the northern paper wasps most homeowners have dealt with before. Workers run 25 to 35 millimeters long, more than an inch, with bigger stingers and a larger volume of venom per sting. The sting is noticeably more painful than what smaller paper wasps deliver.
The defense zone is also wider. Red wasps will attack from 8 to 12 feet around the nest, compared to the 3 to 6 feet typical for northern paper wasps. Many homeowners only learn about that wider perimeter when they walk past a nest they thought was a safe distance away. Multiple stings from a defending colony of 100 to 300 wasps is a serious medical event, especially for children, pets, or anyone with sting allergies.
A pro handles red wasps with full bee-suit protective gear, evening treatment timing when the colony is on the nest, the right product for the larger paper envelope, and a residual on the attachment point after removal. For attic-void nests, void treatment is added so the colony can't retreat into the wall cavity. Single nest removal usually runs $200 to $500. For chronic properties with multiple nests every year, recurring service costs $50 to $120 per month and includes the spring inspection walk.
DIY contact sprays often trigger a defensive swarm before they knock down enough of the colony to matter, and homeowners on ladders with workers in the air is exactly the situation that produces multiple-sting emergencies. The wait-and-see option doesn't apply here: red wasp colonies grow fast in southern climates, and a small founding nest in May is a 200-wasp problem by September.
Red wasp removal is not the same as knocking down a small northern paper wasp nest. Larger colonies, wider defense zones, and bigger stings change the entire approach. Here's what changes when a pro handles it:
Pros confirm red wasp ID versus smaller northern paper wasps. The reddish-brown body, dark smoky wings, and inch-long size change product choice and protective gear.
Red wasps return to the nest at dusk. Evening treatment hits the largest share of the colony at once and avoids the daytime defense response that puts workers in the air.
Larger stingers and wider defense zones mean trained handlers wear sealed bee suits, gloves, and hoods, not the lighter gear that works for smaller paper wasps.
After the nest is treated and extracted, a residual on the original attachment stalk discourages a new queen from rebuilding on the same spot next spring. Attic-void nests get void treatment instead.
Red wasps are an exception to most paper wasp DIY advice. Larger size, wider defense zones, and more painful stings change the calculus, established nests should not be approached without trained handlers and full protective gear.
DIY work for red wasps is identification and observation, not removal:
Professional red wasp work is built around the larger colony scale and wider defense zone. Here's what changes when you call:
Red wasps are larger, more defensive, and sting harder than northern paper wasps. Connect with a local specialist for evening pro treatment, full protective gear, and complete nest removal.

Direct answers to what homeowners ask most about identification, the southern range, and safe pro removal.
Red wasps (Polistes carolina and related species) are paper wasps distinguished by their predominantly reddish-brown to dark red body coloring, with darker (nearly black) wings. They are slender, about 1 inch long, with the characteristic long dangling legs visible in flight that all paper wasps display. Their nests are the typical open, umbrella-shaped paper wasp comb attached by a single stalk to eaves, porch ceilings, door frames, and other sheltered overhangs. Red wasps are commonly found throughout the southeastern and central United States. They are distinguished from other paper wasp species by their uniformly red-brown coloring, as most other paper wasps have yellow-and-brown or brown-and-orange patterns.
Red wasps are generally comparable in temperament to other paper wasp species, and theyare moderately defensive of their nest but not as aggressively territorial as yellow jackets or bald-faced hornets. They will sting if the nest is directly disturbed, if they are physically threatened, or if someone makes rapid movements close to the nest. However, colonies of red wasps tend to be larger than those of some other paper wasp species, which means more defenders are available when a nest is disturbed. Their stings are painful and can cause significant localized swelling. Like all paper wasps, they build nests in locations where human contact is likely, under eaves, behind shutters, inside grills, and around playground equipment, soaccidental nest disturbance is the most common cause of stings.
Wasps are attracted to sheltered spots near food sources. Eaves, porch ceilings, shutters, and deck railings offer protected nesting sites. Outdoor trash, sugary drinks, pet food, and protein-rich grilling areas provide the food wasps need. Removing old nests (wasps don't reuse them, but the scent attracts new queens), sealing eave gaps, and managing food attractants reduces nesting pressure.
For most people, a wasp sting causes localized pain and swelling that resolves in a few hours. However, wasps can sting multiple times (unlike honeybees), and for individuals with venom allergies, a single sting can trigger anaphylaxis, alife-threatening reaction. If a nest is near a high-traffic area like a doorway, patio, or playground, removal is strongly recommended.
Most providers in our network can schedule an inspection within 24-48 hours. For urgent situations, likeactive structural damage or large colonies, same-week emergency service is often available. Response times depend on your location and the provider's current schedule.
Your provider inspects the property to identify the pest, locate nesting or entry points, and assess the scope of the problem. You get a clear explanation of what they found, what they recommend, and a written scope before any work begins.
Modern pest control products are designed to break down quickly after application and pose minimal risk to people and pets when applied correctly. Most providers ask you to keep kids and pets out of treated areas for 1 to 2 hours while the product dries, after which the area is generally safe again. Always confirm specific re-entry times with your provider, and let them know about pet birds, fish, or reptiles, since some treatments require extra precautions for those species.
