Definity Pest Services · DFW
Mosquitoes in DFW are mainly Culex and Aedes species. Culex mosquitoes are the primary vector of West Nile virus, which Dallas County reports nearly every summer, while Aedes species are aggressive daytime biters. They breed in any standing water and bite within a short range of where they hatch. Effective control combines eliminating breeding sites with targeted treatment of resting areas.
Quick reference
Identification
Small, long-legged flies with a single pair of wings and a piercing proboscis; only females bite, needing a blood meal to produce eggs. Culex tend to bite at dusk and dawn and are the West Nile carriers; Aedes (including the Asian tiger mosquito, with black-and-white legs) bite aggressively during the day. The clearest sign is the biting itself, concentrated around shaded, damp, vegetated areas of the yard.
Where it's found
- Standing water
- Gutters
- Bird baths
- Plant saucers, tarps, and tires
- Shaded, damp vegetation
Risk level
- Disease transmission

Signs of activity
- Biting at dusk, dawn, or during the day
- Biting concentrated in shaded, damp yard areas
- Larvae wriggling in standing water
How Definity treats it
- Inspect the property and eliminate standing-water breeding sites
- Apply larvicide to water that can't be drained
- Treat shaded adult-resting harborage
- Return on a recurring seasonal schedule through mosquito season
How to identify mosquitoes

The clearest sign is the biting itself, concentrated around shaded, damp, vegetated areas of the yard.
Behavior & biology
Mosquitoes need standing water to breed — even a bottle cap's worth. Eggs hatch into aquatic larvae in days during warm weather, so neglected water sources turn into hatcheries fast: clogged gutters, plant saucers, bird baths, tarps, toys, tires, drainage areas, and any container that holds rain. Adults rest in cool, shaded vegetation by day and stay close to where they emerged, which is why yard sources drive most of the biting.
Why mosquitoes matter
Beyond itchy bites, mosquitoes are a genuine public-health concern in North Texas. Culex mosquitoes transmit West Nile virus, which Dallas County health authorities track and respond to nearly every summer, including years with human cases and spraying programs. Mosquitoes can also transmit other viruses and heartworm to dogs. Their presence limits use of yards and outdoor spaces through the long Texas warm season.
DIY vs. professional control
Foggers and citronella offer only brief, surface relief because they don't remove breeding sites or treat where adults rest. Professional mosquito control is systematic: inspect and eliminate or treat standing-water sources, apply larvicide to water that can't be drained, and treat shaded resting harborage on a recurring schedule through mosquito season — which in DFW runs much of the year.
How Definity treats mosquitoes
Definity reduces mosquitoes by inspecting the property for standing-water breeding sites, treating or eliminating them, larviciding water that can't be drained, and treating shaded adult-resting areas on a recurring seasonal schedule. Johnny Lockridge tells customers the single biggest win is removing standing water — dump the saucers, clear the gutters, and you've shut down the hatchery before treatment even starts.
Fast facts
- Culex mosquitoes are the main vector of West Nile virus, which Dallas County reports almost every summer and actively monitors with trapping and, in some years, spraying.
- Mosquitoes can breed in as little as a bottle-cap of standing water, so small overlooked sources — saucers, gutters, toys, tarps — often drive most of a yard's biting population.

Questions, answered
Mosquitoes FAQ
How do I reduce mosquitoes in my yard between treatments?
Eliminate standing water: empty plant saucers, bird baths, and toys; clear clogged gutters; cover or store containers and tires; and fix drainage that holds water. Removing breeding sites is the most effective thing a homeowner can do.
Are mosquitoes in Dallas really a health risk?
Yes. Dallas County reports West Nile virus nearly every summer, carried by Culex mosquitoes, and has had years with human cases and public spraying. Reducing breeding sites and treating resting areas lowers both bites and risk.
