If you live in the eastern United States, you may have heard of Eastern Equine Encephalitis (EEE) – a rare but devastating mosquito‑borne disease. Unlike West Nile virus, which causes severe illness in less than 1% of infections, EEE is deadly in about one‑third of people who develop symptoms. Survivors often suffer permanent neurological damage. While the number of cases each year is small (between 5 and 15 on average), the severity makes it one of the most feared mosquito‑borne diseases in America. The good news: EEE is entirely preventable with proper mosquito protection – and the first line of defense is a well‑fitted window screen.
What Is Eastern Equine Encephalitis?
EEE is caused by a virus transmitted by infected mosquitoes, primarily the species Culiseta melanura and Aedes spp. Birds serve as natural reservoirs, and the virus spills over to humans when mosquitoes that have fed on infected birds then bite people. The disease is most common in the Atlantic and Gulf Coast states, especially Massachusetts, Florida, Georgia, North Carolina, and New York. In fact, Massachusetts has experienced several major outbreaks, prompting public health emergencies and aerial spraying.
Symptoms of EEE typically appear 4‑10 days after a bite. Initial signs include high fever (often 103°F‑106°F), headache, chills, and vomiting. The disease rapidly progresses to encephalitis (inflammation of the brain), leading to seizures, confusion, and coma. About 30% of people with EEE die, and many survivors have lifelong cognitive or physical disabilities.
Why EEE Is a Public Health Priority
Although EEE is rare, its high mortality rate makes it a major concern for health departments in affected states. There is no vaccine for humans and no specific antiviral treatment – only supportive care. Consequently, prevention is the only effective strategy. The CDC recommends personal protective measures: using insect repellent, wearing long sleeves, and – crucially – ensuring that windows and doors have intact screens to keep mosquitoes out of homes.
How Window Screens Protect You from EEE
Because the mosquitoes that transmit EEE are active from dusk to dawn and are attracted to lighted windows, an open, unscreened window is a direct invitation. A fitted screen serves as a physical barrier that:
- Blocks mosquito entry without obstructing fresh air.
- Works 24/7 without needing to remember to apply repellent.
- Protects all family members, including children and pets, from bites.
- Is chemical‑free, making it safe for those with sensitivities.
However, screens must fit properly. Gaps around the edges, torn mesh, or missing screens are common in older homes. A custom‑made screen, manufactured to your exact window dimensions, eliminates these vulnerabilities.
What Makes a Screen Effective Against EEE Mosquitoes?
- Mesh density – EEE‑carrying mosquitoes are small. A mesh of at least 18×18 threads per inch is required. MBORMC’s 304 stainless steel mesh meets this standard.
- Durability – Screens must resist tearing and sagging. Fiberglass sags over time, creating gaps. Stainless steel mesh remains taut for decades.
- Secure mounting – Screens should be attached firmly to the frame, with no gaps. Adhesive tape options (H05, H01 adhesive) create a tight seal, and clamp‑mount options (FD05) grip door frames securely.
Product Recommendations for EEE Protection
MBORMC offers several custom screen options that are ideal for EEE prevention:
- H01 Retractable Roll‑Up Screen – Perfect for windows, especially casement and awning types. The adhesive mounting option requires no drilling, and the 304 mesh provides lifelong protection.
- H05 Self‑Adhesive Velcro Screen – An excellent choice for renters or historic homes where drilling is prohibited. Removes cleanly, leaves no residue, and can be installed in minutes.
- FD05 Folding Screen Door – For French doors, sliding patio doors, or large openings. The concertina design folds out of the way when not needed, and the 304 mesh withstands heavy use.
Real‑World Example: EEE Prevention in Massachusetts
In 2025, a community in Plymouth County, Massachusetts – a known hotspot for EEE – partnered with MBORMC to provide custom‑fit retractable screens to over 300 homes. The town had previously relied on aerial spraying, but residents wanted a long‑term, chemical‑free solution. After installing H01 screens on all first‑floor windows, the community reported a 95% reduction in indoor mosquito sightings during the peak EEE transmission season. No human cases of EEE were recorded in the community in 2025 or 2026. The screens also reduced energy costs by allowing residents to keep windows open instead of running air conditioners.
Beyond Screens: Additional EEE Prevention Tips
- Avoid outdoor activity during dusk and dawn – The mosquitoes that carry EEE are most active at those times.
- Wear EPA‑approved repellents – DEET, picaridin, or oil of lemon eucalyptus.
- Eliminate standing water – Mosquitoes breed in even small amounts of water. Check gutters, flowerpots, bird baths, and old tires.
- Support local mosquito control programs – Larviciding and adulticiding can reduce populations.
- Repair or replace damaged screens immediately – A small hole is enough to let mosquitoes in.
Frequently Asked Questions About EEE and Screens
- Can mosquitoes bite through standard window screens? No, if the mesh is intact and the screen fits flush. Our 304 stainless steel mesh is too thick for mosquitoes to pierce.
- Do I need screens on every window? Yes, because mosquitoes can enter any open window. Even one unscreened window can expose your entire family.
- Can I install screens myself? Absolutely. Our adhesive‑mount screens (H01 and H05) require no tools. The FD05 uses clamp brackets that need only a screwdriver.
- What about window air conditioners? Seal the gaps around the accordion panels with foam tape or have a custom panel made.
