Mosquito Identification, Types & Behavior

Mosquitoes are one of the most significant pests a homeowner deals with, both for the nuisance of the bites and for the diseases they can carry. Across Mira’s service areas, mosquito season runs from late spring through fall, with the longest and most intense activity in Florida and Georgia, where warm pockets can allow year-round breeding. The good news is that mosquitoes are manageable once you understand them. Below, you’ll find how to recognize them, the diseases worth being aware of, and what actually helps reduce them around your home.

IDENTIFICATION

What do mosquitoes look like?

Most people can recognize a mosquito by the time it’s landed on them. What’s less obvious is that different species bite at different times of day, prefer different breeding sites, and carry different disease risks.

A few features all mosquitoes share:

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

If what you’re seeing is small and bites but doesn’t have those long legs or the proboscis, you may be looking at a gnat or a midge, which are different pests handled differently.

Common Types of Mosquitoes

A few groups turn up most often across the Southeast and Midwest:

Asian tiger mosquito (Aedes albopictus): Black-and-white striped legs, and an aggressive day-biter, not just at dawn and dusk. Breeds in tiny pockets of standing water like flowerpots, bottle caps, and gutters. Established across Georgia and Florida and expanding northward, it can carry Zika, dengue, West Nile, and Eastern Equine Encephalitis.
Southern house mosquito (Culex quinquefasciatus): Brown and less distinctive, it bites mainly at dusk and through the night. Breeds in standing water like storm drains, ditches, and neglected birdbaths. It’s the primary West Nile carrier in Georgia and common across the Southeast.
Floodwater mosquitoes (several species): Lay eggs in damp soil that stay dormant until heavy rain hatches them in waves. This is why you can have almost no mosquitoes one week and a surge two days after a thunderstorm. Common across warm, humid regions.

What Every Homeowner Should Know About Mosquitoes

They breed in standing water. Even a bottle cap’s worth, in a gutter, plant tray, or birdbath, is enough for mosquitoes to lay eggs. Removing standing water is the highest-leverage thing you can do on your own property.

Only females bite. Females need blood to produce eggs; males feed on nectar. So the one bothering you is always a female.

They can carry disease, though serious illness is uncommon. Across Mira’s areas, West Nile is the most relevant, active in Ohio, Georgia, and Florida, with a few rarer regional concerns. Mosquitoes also spread heartworm to dogs.

They appear in waves after rain. Floodwater species lay eggs in damp soil that hatch all at once after a storm, which is why you can go from almost none to a swarm in a couple of days.

Not all “mosquitoes” are mosquitoes. Crane flies and midges (Florida’s “blind mosquitoes”) look similar but don’t bite.

When to Call a Professional About Mosquitoes

Most homeowners can meaningfully reduce mosquitoes on their property by removing standing water, repairing screens, and using personal repellent. Professional treatment becomes worth considering when:

You’ve removed the obvious standing water and mosquito activity is still heavy
Your property backs onto wet areas you can’t control, like creeks, drainage easements, wooded lots, or neighbors’ yards
You spend time outdoors and want a reliably reduced-mosquito perimeter around a yard, deck, or pool area
You have specific events (an outdoor gathering, a wedding, a season of backyard time) that warrant a treated yard
A local health advisory has been issued for mosquito-borne disease in your area
You have a young child, pregnant family member, or pet who’d benefit from fewer mosquitoes around

Professional mosquito control is typically a perimeter treatment: a residual application targeting the shaded vegetation and resting spots where adult mosquitoes hide during the day, along with treating known or likely breeding sites. It won’t remove every mosquito, but it can substantially reduce activity for a few weeks at a time, which is often enough to make outdoor space usable through peak season.

Mira offers mosquito control across our Atlanta, Tampa, Orlando, and Ohio service areas, with seasonal programs built around local mosquito activity.

Mosquito FAQ

What time of day are mosquitoes most active?

It depends on the species. Asian tiger mosquitoes (common in Georgia and Florida) bite throughout the day, with peaks in the morning and late afternoon. Southern house mosquitoes (the primary West Nile vector) are most active at dusk and through the night. If you’re getting bitten in the middle of the day in the Southeast, it’s almost certainly an Asian tiger mosquito.

Why are there so many mosquitoes after it rains?

Two reasons. Heavy rain fills small containers, puddles, and damp soil where mosquito eggs were already laid, triggering them to hatch in waves. Some species — floodwater mosquitoes — lay eggs specifically in soil that stays dormant until rain arrives, then hatch en masse. Both effects mean mosquito populations can surge within days of a thunderstorm.

Do mosquitoes serve any purpose?

Ecologically, yes — mosquito larvae are food for fish, birds eat adult mosquitoes, and some mosquito species pollinate plants. Practically, around homes, that ecological role doesn’t translate into a reason to tolerate them. Most mosquito reduction around a home doesn’t meaningfully affect the broader ecosystem.

Are some people more attractive to mosquitoes than others?

Yes, this is real. Mosquitoes detect CO₂ (so people who exhale more — larger people, pregnant people, people who are exercising — attract more), body heat, lactic acid in sweat, and certain skin bacteria. It varies person to person and isn’t something you can fully control, but it does mean some family members will reliably get bitten more than others.

How long does mosquito control treatment last?

For a professional perimeter treatment, activity is typically reduced for 3-4 weeks before re-treatment is recommended during peak season. The exact duration depends on weather, rain frequency, and how heavily the property is being re-invaded from surrounding areas. This is why most mosquito programs are scheduled monthly through the active season rather than treated as one-time service.
