Quick answer
Eastern equine encephalitis, or EEE, is a rare but potentially severe disease transmitted through the bite of an infected mosquito. Georgia homeowners cannot identify an infected mosquito by sight, so prevention should focus on avoiding bites, maintaining screens, removing standing water, and reducing mosquito activity around frequently used outdoor areas. Severe headache, high fever, confusion, seizures, or other neurologic symptoms require immediate medical evaluation.
EEE receives attention because the illness can be serious, not because every mosquito bite creates a likely infection. Georgia Department of Public Health guidance emphasizes bite prevention and environmental management. A professional mosquito-control service can be one part of that plan, but it cannot replace repellent, clothing, screens, water removal, or medical care.
Medical warning: This page provides general prevention information. Contact a healthcare professional for symptoms or an exposure concern. Call 911 for a seizure, severe confusion, loss of consciousness, difficulty breathing, or another medical emergency.
What Is Eastern Equine Encephalitis?
EEE is caused by Eastern equine encephalitis virus. In nature, the virus is maintained in a mosquito-and-bird cycle. Other mosquito species can act as bridge vectors by feeding on infected birds and later biting people or horses. People do not catch EEE from ordinary contact with a horse, bird, or another person.
Most people infected with the virus do not develop severe neurologic disease. When serious illness occurs, it can involve inflammation of the brain, called encephalitis, or the membranes around the brain and spinal cord, called meningitis. That is why unusual neurologic symptoms need prompt evaluation rather than watchful waiting at home.
How EEE Risk Should Be Understood in Georgia
Georgia has the climate and habitat needed for many mosquito species: long warm seasons, frequent rainfall, wooded areas, wetlands, stormwater features, drainage systems, and containers around homes. EEE is considered an endemic mosquito-borne disease in Georgia, meaning the virus can be maintained in the region. Human cases are still rare.
Risk is not evenly distributed from one yard or week to the next. Mosquito species, local surveillance, rainfall, habitat, time spent outdoors, repellent use, and personal exposure all matter. A single neighborhood mosquito sighting cannot tell you whether EEE virus is present.
Public-health alerts, mosquito-surveillance results, and animal cases can signal local activity, but prevention should not begin only after an alert. The same steps also help reduce exposure to West Nile virus and other mosquito-borne illnesses. Homeowners following the local West Nile mosquito updates for Atlanta can use one layered prevention routine for both concerns.
Symptoms and When to Seek Medical Care
Illness can begin with nonspecific symptoms such as fever, chills, body aches, or joint pain. Severe disease may include headache, vomiting, confusion, unusual sleepiness, disorientation, seizures, weakness, or coma. Symptoms alone cannot confirm EEE, and other urgent conditions can look similar.
Contact a healthcare professional promptly if illness follows mosquito exposure. Seek emergency care for neurologic symptoms, a seizure, severe weakness, altered mental status, or rapidly worsening illness. Do not wait for a pest inspection or mosquito treatment before obtaining medical help.
The Most Effective Prevention Uses Several Layers
Use an EPA-registered repellent
Choose an EPA-registered repellent and follow its label. Common active ingredients include DEET, picaridin, IR3535, and oil of lemon eucalyptus or para-menthane-diol in products approved for the user’s age. The EPA repellent search tool can help compare protection time and active ingredients.
Apply repellent to exposed skin and clothing only as the label permits. Adults should apply products to children rather than letting children handle them. Do not apply repellent beneath clothing, on irritated skin, or near eyes and mouths. When using sunscreen, Georgia DPH advises applying sunscreen first and repellent afterward.
Cover exposed skin when practical
Loose-fitting long sleeves, long pants, socks, and closed shoes reduce exposed skin. Clothing and gear can be treated with permethrin when the product is specifically labeled for that use; permethrin clothing products should not be applied directly to skin.
Keep mosquitoes outside
Repair torn window and door screens, close gaps around screen frames, and make sure doors shut tightly. In bedrooms and frequently used rooms, air conditioning and intact screening can reduce indoor exposure.
Use prevention whenever mosquitoes are active
Some mosquito species are most active around dawn and dusk, while others bite during the day or night. Time-of-day advice should not replace repellent. If mosquitoes are biting, use protection.
Where Mosquitoes Breed Around a Home
Many container-breeding mosquitoes need only a small amount of water. The water does not have to look like a pond. After rain or irrigation, inspect:
- plant saucers, buckets, watering cans, and unused pots;
- children’s toys, play equipment, tarps, and wheelbarrows;
- birdbaths and outdoor pet bowls;
- clogged gutters and downspout extensions;
- trash, recycling, lids, cups, and discarded containers;
- tire swings, stored tires, and equipment depressions;
- pool covers, neglected fountains, and poorly maintained water features;
- tree holes, corrugated drainpipe, catch basins, and low areas that stay wet.
Emptying water once is not enough if rain or irrigation refills the container. Make a weekly route around the property and repeat it after storms. Scrub containers that can hold eggs on the sides, cover stored water tightly, maintain pools and fountains, and correct drainage where practical.
What Professional Mosquito Service Can and Cannot Do
A property-level service begins by reviewing where people spend time outdoors, where vegetation provides shaded resting areas, and where water may support breeding. Treatment may target labeled areas where adult mosquitoes rest or use other methods appropriate to the site. Recommendations may include trimming dense vegetation, correcting drainage, or changing container-storage habits.
Service can reduce mosquito activity, but mosquitoes can fly in from neighboring properties, public land, wetlands, drains, and other untreated areas. Rain, irrigation, vegetation growth, and new standing water can also change conditions between visits. No responsible service should promise a mosquito-free yard or guaranteed disease prevention.
A Practical Weekly Mosquito Checklist
- Walk the property after rain and empty standing water.
- Scrub and refill birdbaths and pet bowls.
- Check gutters, drains, pool covers, tarps, and corrugated pipes.
- Repair screens and make sure exterior doors close properly.
- Keep repellent where it will be used before outdoor activity.
- Wear coverage appropriate for the activity and temperature.
- Report stormwater or drainage problems on public property to the responsible local agency.
- Follow current Georgia DPH and county health information rather than social-media rumors.
Special Considerations for Horses and Pets
EEE is especially important for horses. Horse owners should consult a veterinarian about vaccination and timing before mosquito season; a pest-control company does not provide veterinary advice. Maintain water troughs and farm containers so they do not become unmanaged breeding sites.
Keep pets on veterinarian-recommended preventive care and do not apply human insect repellent to an animal unless a veterinarian specifically directs it. Products safe for one species may be unsafe for another.
What Not to Do
- Do not assume every mosquito carries EEE or that illness can be diagnosed from a bite mark.
- Do not use outdoor pesticide products indoors or apply any product beyond its label.
- Do not rely on candles, electronic devices, or one yard treatment as the only protection.
- Do not mix repellents or pesticides into homemade combinations.
- Do not delay medical care for severe symptoms while waiting for mosquito surveillance or property service.
Local Prevention in Marietta and Metro Atlanta
Metro Atlanta properties range from compact city lots to wooded suburban neighborhoods, apartments, community pools, and homes near creeks or stormwater ponds. The useful local strategy is not a list of city names; it is identifying how water, vegetation, screens, and outdoor activity interact at the specific property.
In Marietta, Cobb County, Fulton County, Cherokee County, Paulding County, Douglas County, and nearby communities, warm weather and repeated summer storms can restore breeding sites quickly. Weekly property checks and personal bite protection remain necessary even when professional mosquito service is in place.
Frequently Asked Questions
How common is Eastern equine encephalitis in people?
Human EEE illness is rare, but it can be severe. The practical response is not panic; it is consistent mosquito-bite prevention and prompt medical attention for concerning symptoms.
Can a person catch EEE directly from a horse or another person?
EEE is primarily transmitted through the bite of an infected mosquito. People and horses are generally considered dead-end hosts and do not produce enough virus in the blood to infect mosquitoes.
What symptoms require urgent medical care?
Seek immediate medical evaluation for severe headache, high fever, confusion, seizures, unusual drowsiness, or other neurologic symptoms, especially after mosquito exposure. A pest-control company cannot assess or treat illness.
Does mosquito spraying guarantee protection from EEE?
No. Property treatment may reduce mosquito activity, but no single step prevents every bite. Use a layered plan that includes EPA-registered repellent, protective clothing, screens, and removal of standing water.
How often should standing water be checked?
Inspect the property at least weekly and after rain. Empty, scrub, cover, or discard containers that hold water, and correct drainage problems that allow water to remain.
Add Property-Level Mosquito Control to Your Prevention Plan
Dixie Exterminators provides mosquito service in Marietta and much of Metro Atlanta. Service can help reduce mosquito activity around commonly used outdoor areas, but it should be combined with repellent, screens, protective clothing, and standing-water removal.
