How to Recognize a Mosquito

Most homeowners can identify a mosquito by the time it lands on them. What most people don’t know is that certain species of mosquitoes bite at different times of day, prefer different breeding sites, and carry different disease risks.

Key features all mosquitoes share:

• Small, slender body (typically about ¼ inch long)
• Long, thin legs
• One pair of wings (mosquitoes are true flies — order Diptera)
• A long, thin proboscis used for feeding (only females bite; males feed on nectar)
• High-pitched whine from rapid wingbeats

The three species groups most homeowners encounter across the Southeast and Midwest:

• Asian tiger mosquito (Aedes albopictus): Black-and-white striped legs. Bites aggressively during the day, not just dawn and dusk. Breeds in tiny pockets of standing water like flowerpots, bottle caps, and gutters. Established across Georgia and Florida; expanding northward. Carries Zika, dengue, West Nile, and Eastern Equine Encephalitis. The most aggressive day-biter most homeowners will encounter.
• Southern house mosquito (Culex quinquefasciatus): Brown, less distinctive in appearance, bites primarily at dusk and through the night. Breeds in standing water — storm drains, ditches, neglected birdbaths. The primary West Nile virus vector in Georgia. Common across the Southeast.
• Floodwater mosquitoes (multiple species): Lay eggs in damp soil that stay dormant until heavy rain causes them to hatch in waves. Why you can have almost no mosquitoes one week and a massive surge two days after a thunderstorm. Common across all warm and humid regions.

If what you’re seeing is small and bites but doesn’t have the long legs or proboscis described above, you may be looking at a gnat or a midge; different pests, treated differently.

Where Mosquitoes Breed

The single most important fact about mosquito control is that mosquitoes need water to reproduce, and almost any amount of water will do.

Mosquito eggs are laid in standing water or in soil that will hold water after rain. The eggs hatch into larvae that live and feed in the water for a few days to a couple of weeks before maturing into adults. Without water, no eggs hatch. With water, populations can double in as little as a week.

Common breeding sites around homes:

• Clogged gutters and gutter joints holding water
• Flowerpot saucers, plant trays, and unused planters
• Birdbaths, pet water bowls, and ornamental fountains without circulation
• Buckets, kids’ toys, tarps, and any object collecting rainwater
• Tire ruts, low spots in the yard, and damp soil after heavy rain
• Storm drains, ditches, and storm-related pooling
• Unused pools, neglected hot tubs, and rain barrels without screens

Asian tiger mosquitoes don’t need much. A bottle cap of water is enough. This is why simply removing standing water  is the single highest-leverage thing a homeowner can do to reduce mosquito populations on their own property.

Keep in mind: this works for breeding on your property, but mosquitoes fly several hundred feet from their breeding sites. If a neighbor has a neglected pool or your yard backs onto a wet area, your eliminating sources at home reduces but doesn’t solve the problem.

Diseases Mosquitoes Can Carry

Mosquitoes are vectors for several diseases that exist in the United States. Across Mira’s service areas, the relevant ones are:

• West Nile virus (WNV): The most common mosquito-borne illness in the U.S. and across Mira’s footprint. Most infections cause no symptoms; about 1 in 5 develop fever, headache, body aches, or rash; about 1 in 150 develop serious neurological illness. Spread primarily by Culex (Southern house) mosquitoes. Active in all three Mira primary states (OH, GA, FL).
• Eastern Equine Encephalitis (EEE): Rare but serious. Causes inflammation of the brain in severe cases; case fatality is high. Geographically concentrated along the East Coast and in pockets of the Gulf states. Sporadic cases reported in Georgia and Florida.
• Zika virus: Most cases in the U.S. are travel-related, but local transmission has been documented in Florida and southern Texas. The primary concern is birth defects in babies born to mothers infected during pregnancy.
• La Crosse encephalitis: Most common in the Midwest and Appalachian regions. Generally mild but can be serious in children. Occasional cases in Ohio.
• Heartworm (dogs): Not a human disease but worth mentioning. Mosquitoes transmit heartworm to dogs, which is serious and preventable. Common across all three states.

Severe mosquito-borne disease is uncommon, but it does happen, and risk varies year to year based on weather, mosquito populations, and bird reservoir populations. Local health departments (Georgia DPH, Florida DOH, Ohio DOH) track activity and issue advisories when local transmission is detected.
