When you think of Washington, D.C., you might picture historic landmarks, cherry blossoms, or bustling politics—not mosquitoes. But the warm, humid summers in the DMV (D.C., Maryland, Virginia) make this region a hotspot for mosquito activity, and with them comes the risk of mosquito-borne diseases.
In this post, we’ll break down the most common mosquito-borne diseases in the D.C. area, how to spot the symptoms, and how Mosquito Sheriff can help protect your home and family.
Common Mosquito-Borne Diseases in the D.C. Area
1. West Nile Virus
The West Nile virus (WNV) is the most frequently reported mosquito-borne illness in the D.C. area. While most infected individuals show no symptoms, about 1 in 5 will develop fever, headache, body aches, and fatigue. In severe cases, WNV can cause neurological issues such as encephalitis or meningitis.

2. Zika Virus
Though rare in recent years, Zika remains a concern during warmer months, especially for pregnant women. It has been linked to birth defects and may cause fever, rash, joint pain, and conjunctivitis.
3. Eastern Equine Encephalitis (EEE)
EEE is extremely rare but potentially fatal. Symptoms include high fever, stiff neck, headache, and seizures. It’s more commonly reported in neighboring mid-Atlantic states but remains on public health watchlists in D.C.
4. La Crosse Encephalitis
More common in children, this disease can lead to seizures and neurological complications. While cases are sporadic, the mosquito species responsible is active in forested and suburban areas around D.C.

If you or a family member experiences any of the following after a mosquito bite, consult a healthcare provider:
-

Rash or joint pain
