If you’ve ever spent a summer afternoon on a porch in the Panhandle or down near the Everglades, you’ve probably seen that flash of deep, angry crimson. It isn't a bird. It isn't a butterfly. It’s the red wasp in Florida, and honestly, they are some of the most misunderstood—and frankly, intimidating—insects in the Sunshine State. People see that solid mahogany-red body and immediately think they’re looking at a flying tank designed solely to ruin a backyard barbecue.
They’re big.
They’re fast.
But are they actually the monsters everyone makes them out to be? Well, yes and no. Florida is home to two primary species that people usually call "red wasps": Polistes carolina and Polistes perplexus. To the untrained eye, they look identical. They both belong to the paper wasp family, meaning they’re the architects behind those grey, umbrella-shaped nests you find tucked under your eaves or inside your mailbox.
Why Red Wasps in Florida Seem So Aggressive
Most folks believe these wasps hunt humans for sport. They don't. But if you accidentally bump a nest while painting your shutters or trimming the hedges, you’re going to have a very bad day. Unlike honeybees, which die after one sting, a red wasp can tag you multiple times without breaking a sweat. Their venom is packed with pheromones that basically act as a "hit" signal to the rest of the colony. One sting often leads to three or four more as the sisters (and yes, they are almost all females in the colony) rush out to defend the homestead.
Nature is weird. In Florida, the heat makes everything move a little faster, and that includes insect metabolism. During the peak of July, these wasps are at their most active. They spend their days hunting caterpillars and flies, which actually makes them "beneficial" insects for gardeners. They’re basically free pest control. Of course, that’s small comfort when a two-inch-long red insect is buzzing three inches from your nose.
Scientists like those at the University of Florida’s IFAS Extension have noted that Polistes carolina is particularly fond of nesting in protected, dark cavities. This is why they love your attic vents. They aren't trying to move in with you; they’re just looking for a spot where the torrential Florida rain won’t melt their paper homes. The nests are made from chewed-up wood fibers mixed with their saliva. It’s a literal spit-and-wood-pulp mansion.

Identifying the Real Culprit
You’ve got to be careful with identification. Not everything red and winged is a red wasp.
Sometimes people mistake the Cicada Killer for a red wasp because they are massive. But Cicada Killers are usually more solitary and have yellow markings. The true red wasp is almost entirely reddish-brown from head to stinger. If you see a wasp that looks like it was dipped in a bucket of dark cherry paint, that’s your target.
Another look-alike is the Mahogany Wasp, which is just another common name for certain color variations of paper wasps. Honestly, the taxonomy can get a bit muddy for the average homeowner. What matters is the behavior. Paper wasps have long legs that dangle down when they fly. It looks a bit lazy, sort of like they’re dragging their landing gear.
The Sting: What Really Happens to Your Body
Let’s talk about the pain. On the Schmidt Sting Pain Index—yes, a real thing created by the late entomologist Justin O. Schmidt—the paper wasp usually ranks around a 2 or 3. He described the sensation as "caustic and burning," comparing it to spilling a beaker of hydrochloric acid on a paper cut.
It’s sharp. It lingers.
For most of us, it’s just a localized swelling. But Florida’s climate adds a layer of complexity. Sweaty skin can lead to secondary infections if you scratch the sting site with dirty hands. And then there’s the allergy factor. Anaphylaxis isn't a joke. If you get stung and start feeling dizzy or your throat feels tight, you need to get to an ER in Orlando, Miami, or wherever you are, immediately. Don't "wait and see."

Dealing With Nests Without Burning Your House Down
I’ve seen people try some wild stuff to get rid of red wasps in Florida. Please, for the love of everything, do not use gasoline. Do not use a flamethrower made from a hairspray can. You will end up on the evening news for all the wrong reasons.
The best way to handle a nest is at night or at the very crack of dawn. Wasps are ectothermic—they rely on external heat. When it’s cool, they’re sluggish. They also don't see particularly well in the dark.
- The Soapy Water Trick: If the nest is small and reachable, a spray bottle with heavy dish soap and water can actually ground them. The soap breaks the surface tension of the water and clogs their breathing pores (spiracles). They suffocate almost instantly. It’s much safer than dousing your porch in toxic chemicals.
- Commercial Foaming Sprays: If you go the store-bought route, look for the "foaming" variety that can shoot 20 feet. The foam traps the wasps on the nest so they can't fly out and attack you while you're standing on a ladder.
- Professional Intervention: If the nest is inside a wall or high up in a soffit, call a pro. In Florida, companies like Massey Services or Hulett deal with these daily. It’s worth the hundred bucks to avoid a trip to the hospital.
Why They Love Your Pool
If you have a pool, you’ve likely seen red wasps "skating" on the surface of the water. They aren't swimming. They’re drinking. They need water to regulate the temperature of the nest and to mix with the wood pulp for building.
It’s annoying because they often get sucked into the skimmer. Then, you go to empty the basket, and—BAM—you get stung by a half-drowned wasp that is very much alive and very cranky.
Misconceptions and Florida Folklore
There’s a common myth in the South that red wasps are "smarter" than yellow jackets. While "smart" is a big word for an insect, research published in journals like Ethology suggests that some paper wasps can actually recognize individual faces of other wasps in their colony. They have a complex social hierarchy. They remember who is the boss.
They also tend to return to the same nesting sites year after year. If you had a red wasp problem on your back porch last year, you’ll probably have one this year unless you seal the entry points. They leave behind chemical markers that say, "This is a great spot for a nursery."

Keeping Them Away (The Realistic Way)
You’re never going to fully "wasp-proof" a Florida home. It’s impossible. This state is a swampy paradise for bugs. However, you can make your property less attractive to them.
Decoy nests sometimes work. You can buy these little brown paper lanterns that look like a rival colony's nest. Since red wasps are territorial, they might see the decoy and decide to set up shop in your neighbor's yard instead. It’s about 50/50 on effectiveness, but it’s a cheap experiment.
Keep your trash cans sealed. While red wasps prefer live prey, they aren't above scavenging for sugary liquids or protein scraps left out after a tailgate.
Actionable Steps for Florida Residents
If you encounter a red wasp today, don’t panic. If you swat at it, you’re basically initiating a fight. Just move away slowly.
If you find a nest:
- Evaluate the size. If it’s bigger than a baseball, think twice before DIY-ing.
- Check for "lookouts." Usually, one or two wasps stay on the outer rim of the nest specifically to watch for threats.
- Use LED lights if you’re working at night; wasps are less attracted to the UV spectrum of LEDs than they are to traditional incandescent bulbs.
- Seal your attic vents with fine mesh screen. This is the single most effective way to keep them out of your home's structure.
The red wasp in Florida is a permanent part of the landscape. They’ve been here longer than the theme parks and the snowbirds. Respect their space, keep your eyes peeled when reaching into dark corners, and always have a can of spray—or a bottle of soapy water—ready during the humid months of July and August. They aren't out to get you, but they definitely won't back down from a lopsided fight.
