Mosquito Control Services in San Antonio, TX
San Antonio’s warm, humid climate makes it one of the most mosquito-active cities in Texas. From March through late October, species like Aedes aegypti and Culex quinquefasciatus breed in standing water across yards, gutters, and landscaping – bringing itchy bites and real health risks including West Nile virus and Zika.
At Thick Green Healthy Lawn & Pest, we provide targeted mosquito control treatments for homes and businesses across the San Antonio metro area. Our barrier spray treatments reduce mosquito populations within 24–48 hours, and our seasonal programs keep your yard protected all season long.

How Our Mosquito Treatment Works
Every property is different, so we start with an inspection before we spray a single drop. Here’s our process:
1. Property Inspection
Our technician walks your entire yard looking for breeding sites (standing water in gutters, flower pots, tree holes, drainage areas) and resting spots where adult mosquitoes shelter during the day (shrubs, patios, overhangs, fence lines, under decks).
2. Barrier Spray Treatment
We apply a fine mist to foliage, fence lines, under decks, around patios, and along entryways – every surface where mosquitoes land and rest. Most homeowners see a major reduction in mosquito activity within one to two days.
3. Breeding Site Elimination
Standing water sources are treated with larvicide or flagged for removal. We’ll point out problem areas you can address between visits, like pet bowls, bird baths, and clogged gutters.
4. Seasonal Protection Plan
Treatments last approximately 21–30 days. For continuous protection during mosquito season (March through October), we offer recurring treatment plans so you don’t have to think about it.
When Is Mosquito Season in San Antonio?
Mosquitoes become active once evening temperatures consistently reach 50°F or higher, which typically happens in early March in the San Antonio area. Activity peaks from June through September when temperatures stay above 80°F and humidity is high. The season winds down in late October as nighttime temperatures drop.
San Antonio is home to over 50 mosquito species. The two you’re most likely dealing with are:
- Aedes aegypti  – the day-biting mosquito that carries Zika and dengue. Breeds in small containers of standing water around your home.
- Culex quinquefasciatus  – the dusk and dawn biter that carries West Nile virus. Breeds in larger water sources like storm drains and ditches.
The City of San Antonio Metro Health Department runs its own mosquito surveillance program on public property – but your yard is your responsibility. That’s where we come in.

Mosquito Prevention Tips for Your San Antonio Yard
Professional treatments do the heavy lifting, but these habits between visits make a real difference:
- Dump standing water weekly – flower pots, bird baths, pet bowls, toys, and tire swings are all breeding sites.
- Keep grass mowed short – mosquitoes rest in tall grass during the day. Our lawn mowing service helps with this.
- Trim shrubs and clear debris – overgrown landscaping gives mosquitoes shade and shelter. Our tree and shrub care keeps vegetation managed.
- Clean gutters – clogged gutters are one of the most common overlooked breeding sites in San Antonio.
- Use fans on patios – mosquitoes are weak fliers. Even a light breeze disrupts their ability to land.
- Plant natural repellents – citronella, lavender, basil, and marigolds can help deter mosquitoes around seating areas.
Frequently Asked Questions
Most residential barrier spray treatments start between $75 and $150 per application, depending on your yard size and the level of infestation. Seasonal plans with recurring monthly treatments typically offer a lower per-visit cost. We provide free estimates so you know exactly what to expect before we start.
During mosquito season (March through October in San Antonio), treatments every 21 to 30 days provide the best protection. One-time sprays help for events, but recurring treatments are what keep populations consistently low throughout the season.
Yes. We use products that are specifically formulated to target mosquitoes while being gentle on people, pets, and beneficial insects. We recommend staying off treated surfaces until the spray dries, which usually takes 30 to 60 minutes. After that, your yard is safe for normal use.
Mosquito activity typically begins in early March when evening temperatures consistently reach 50°F or higher. Peak season runs from June through September. We recommend scheduling your first treatment in late February or early March to get ahead of the population before it builds.
Professional mosquito treatments significantly reduce the mosquito population on your property, which directly lowers your risk of bites. San Antonio has had confirmed West Nile virus cases in recent years, so reducing exposure through professional control combined with personal prevention measures (wearing repellent, eliminating standing water) is the most effective approach.
