Mosquito Control in San Antonio, TX

Mosquito Species Active in San Antonio & Surrounding Areas

San Antonio and its surrounding areas are home to several mosquito species, each with distinct breeding habits and disease-transmission risks. Three species drive the most concern in Bexar County.

Aedes aegypti is an aggressive daytime biter that thrives in urban environments, breeding in any container that holds water, including bottle caps, flowerpots, and clogged gutters, and it transmits Zika, dengue, and chikungunya. Aedes albopictus, the Asian tiger mosquito, shares the same daytime biting habits and can carry the same viruses. Culex quinquefasciatus, the southern house mosquito, is the primary vector for West Nile virus in the region and is especially active in the drainage channels and greenbelts throughout Bexar County. Knowing which species are present is the first step toward effective control. For more on the West Nile threat in Texas, see the Texas Department of Health and Human Services resource on West Nile virus.

How Our Mosquito Spraying Treatment Works

Mosquitoes can complete their egg-to-adult life cycle in as little as one to two weeks under favorable conditions, which means a missed treatment window can allow populations to rebound quickly. Our process is designed to interrupt that cycle at every stage, not just knock down the adults you see today.

What Happens During a Treatment Visit

When our technician arrives, they inspect your property first to identify where mosquitoes and larvae are present. The mosquito spraying treatment then covers your entire property, with focused attention on the areas where mosquitoes concentrate: trees, gutters, leaf litter, patios, and overhangs. Once the treatment is complete, we walk you through our maintenance plan options and recommend follow-up treatments to help keep populations from rebounding.

When to Start Mosquito Spraying in San Antonio

The best time to start is early spring, before populations have a chance to build. Bexar County’s mosquito season runs roughly March through November, and consistent treatments from spring through fall provide ongoing control. Starting early disrupts the breeding cycle before peak summer activity, which can make each subsequent treatment more effective.

How to Reduce Mosquito Breeding in Your Yard

Professional treatment works best when paired with a few habits at home. Mosquitoes need standing water to breed, and eliminating those sources cuts off the next generation before it starts.

Steps you can take to reduce mosquito breeding in your yard:

• Remove Standing Water: Inspect your yard regularly for containers, puddles, or objects that collect water, including flowerpots, buckets, old tires, clogged gutters, birdbaths, and toys. Empty or dispose of them to stop water from accumulating.
• Clean Gutters & Downspouts: Clogged gutters trap water and create ideal breeding conditions. Keep them clear of debris.
• Fix Leaks: Repair dripping faucets and plumbing leaks. Even a small, persistent drip can attract mosquitoes.
• Maintain Your Yard: Keep your lawn and garden well-drained. Fill in low-lying areas where water pools, and avoid overwatering.
• Use Mosquito Dunks or Larvicides: For water features you can’t empty, such as ponds or rain barrels, mosquito dunks and larvicides target larvae before they mature into adults.
• Keep Swimming Pools Clean: A properly maintained, chlorinated pool is far less likely to become a breeding site.
• Maintain Ornamental Ponds & Fountains: Use mosquito fish or install a pump to keep water circulating. Stagnant water invites mosquitoes.
• Install Screens: Make sure windows and doors have intact screens to keep mosquitoes out of your home.
• Trim Vegetation: Cut back dense vegetation and tall grass, which provide shelter for resting adult mosquitoes.
• Use Mosquito-Repelling Plants: Citronella, lavender, and marigolds have natural repellent properties. Plant them near outdoor seating areas for an added layer of deterrence.
• Consider Mosquito Nets or Traps: Nets over outdoor seating and strategically placed traps can further reduce activity in your yard.
• Limit Outdoor Activity at Dawn and Dusk: Mosquitoes are most active during these windows. When possible, plan outdoor time for mid-morning or early evening instead.
