Wasps and hornets are a common sight across Georgia, especially through the warmer months. These insects play an important role in the ecosystem, controlling other pests and pollinating plants, but when they build nests close to your home they can quickly become a safety concern. From their ability to sting more than once to their often-hidden nests, both wasps and hornets are worth understanding. This guide will help you identify the species most common in Georgia, understand their behavior and the risks they carry, and learn how to prevent or address a nest safely.
Common Wasps in Georgia
Paper Wasps
- Identification: Slender body with long legs, reddish-brown or black coloration, and yellow markings (Polistes spp.).
- Behavior: Paper wasps construct umbrella-shaped nests under eaves, decks, or tree branches. They are generally non-aggressive but will defend their nests if provoked.
- Risks: Their stings are painful and can lead to swelling or allergic reactions. Disturbing their nest can result in aggressive behavior.
Yellowjackets
- Identification: Stocky bodies with bold black and yellow patterns (Vespula spp.).
- Behavior: These highly aggressive wasps build nests underground or inside wall cavities. They become especially troublesome in late summer, when natural food becomes scarce.
- Risks: Yellowjackets can sting repeatedly and attack in groups, which makes them a real risk to anyone nearby.
Cicada Killers
- Identification: Large solitary wasps with a black body and yellow markings (Sphecius speciosus).
- Behavior: These wasps dig burrows in sandy or loose soil and hunt cicadas. Despite their intimidating size, they are non-aggressive.
- Risks: Cicada killers rarely sting people, but their size and loud buzzing can be unnerving.
Hornets in Georgia
Bald-Faced Hornets
- Identification: Black and white body with a rounded shape (Dolichovespula maculata).
- Behavior: Bald-faced hornets build large, football-shaped paper nests in trees or on structures and are very protective of them.
- Risks: Their stings are intensely painful, and their defensiveness near a nest makes them a hazard to anyone close by.
European Hornet
- Identification: Larger than most wasps, with a reddish-brown body and yellow stripes (Vespa crabro). First reported in North America in 1840, it is now widespread across the eastern United States, including Georgia.
- Behavior: European hornets nest in hollow trees, wall voids, or abandoned animal burrows. They are not overly aggressive but will defend a nest if disturbed.
- Risks: They can become a nuisance around homes by preying on insects and occasionally damaging fruit trees.
Yellow-Legged Hornet (Invasive)
In August 2023, the Georgia Department of Agriculture confirmed the yellow-legged hornet (Vespa velutina) near Savannah, the first live detection of this species in the United States. Native to Southeast Asia, it is a species Georgia officials are actively tracking.
- Identification: Roughly 2 centimeters long, with distinct yellow legs and varying body and head coloring.
- Nesting: It builds large, egg-shaped paper nests high off the ground, often in trees. A single nest can house thousands of workers, far larger than a native hornet nest.
- Why it matters: The yellow-legged hornet preys on honeybees, which raises concern for Georgia’s agriculture and honey production. If you think you have seen one or spotted its nest, report it to the Georgia Department of Agriculture. Early reporting helps the state track and manage its spread.
How to Identify Wasp Nests
Recognizing wasp nests early can help you address infestations before they become a significant problem. Here’s what to look for:
- Paper Wasp Nests: Umbrella-shaped and often found under eaves, decks, or other sheltered areas.
- Yellowjacket Nests: Hidden underground or in wall cavities, making them harder to spot.
- Hornet Nests: Large, football-shaped structures made from paper-like material, often hanging in trees or on buildings.
- Solitary Wasp Burrows: Small holes in sandy or loose soil, often surrounded by dirt mounds.

Are Wasps Dangerous?
Wasps can pose several risks, especially if they feel threatened or their nests are disturbed:
- Stings: Wasps and hornets can sting more than once, injecting venom that causes pain and swelling. For people with allergies, a sting can lead to a severe, even life-threatening reaction.
- Allergic Reactions: Symptoms range from mild itching and swelling to serious breathing difficulty that needs immediate medical attention.
- Property Concerns: Nests built in wall cavities or other structural areas can cause damage over time.
Because of those risks, professional wasp and hornet control is usually the safest way to handle a nest, rather than tackling it yourself.
How To Prevent Wasps Around Your Home
A few preventative steps can lower the chance of wasps or hornets settling near your home:
Seal Entry Points
Check your home for gaps or cracks in walls, vents, and windows. Sealing them keeps wasps and hornets from nesting inside structures.
Remove Food Sources
Wasps are drawn to sweet and protein-rich foods. Keep trash cans sealed tightly and clean up sugary spills and food waste promptly.
Inspect Outdoor Areas
Check regularly for early signs of nests under eaves, in bushes, and around decks or outdoor furniture. Clearing a small nest early can prevent a larger one later.
When to Call a Professional
DIY approaches can seem appealing, but professional pest control offers a few real advantages when it comes to stinging insects:
- Safety: Professionals are equipped to handle nests while minimizing the risk of stings and allergic reactions.
- Thoroughness: Experts can find hidden nests and address the whole problem, not just the wasps you can see.
- Ongoing prevention: Professional treatment helps keep wasps and hornets from settling back in, for lasting peace of mind.

Frequently Asked Questions
What are the most common wasps in Georgia? Paper wasps, yellowjackets, and cicada killers are the most common wasps Georgia homeowners encounter, along with bald-faced and European hornets.
Are hornets in Georgia dangerous? Most hornets are not aggressive unless their nest is threatened, but their stings are painful and can cause allergic reactions. Nests close to the home are best handled by a professional.
What is the yellow-legged hornet, and why is it a concern in Georgia? The yellow-legged hornet is an invasive species first detected near Savannah in 2023. It preys on honeybees, which makes it a concern for Georgia agriculture. Suspected sightings should be reported to the Georgia Department of Agriculture.
What is the difference between a wasp and a hornet? Hornets are a type of wasp. The term “hornet” usually refers to larger species that build enclosed, football-shaped paper nests, while “wasp” covers a broader group that includes paper wasps and yellowjackets.
When should I call pest control for wasps or hornets? Reach out if a nest is near your home or in a high-traffic area, if you are seeing wasps or hornets regularly, or if anyone in the household has a sting allergy.
