Mosquito Control for San Antonio Backyards

How to cut down mosquitoes in your San Antonio backyard by removing breeding sites, plus how professional barrier treatments keep outdoor spaces usable.

By Time's Up Pest Control. Published 2026-10-22.

Key Takeaways

  • Mosquitoes breed in very small amounts of standing water, and some can go from egg to adult in about a week.
  • Emptying containers weekly is the single most effective thing a homeowner can do.
  • Barrier treatments target the shady plants where adult mosquitoes rest during the day.
  • San Antonio's long warm season means mosquito control works best as an ongoing program.

In San Antonio, mosquito season can run from spring rain to the first real cold front in late fall. Mosquitoes aren't just an annoyance at a backyard barbecue. Some species can carry diseases like West Nile virus. A few habits and the right treatment plan can take your yard back.

Know Your Backyard Mosquitoes

  • Aedes mosquitoes (like the Asian tiger mosquito) bite during the day and breed in small containers: flowerpot saucers, buckets, toys and clogged gutters.
  • Culex mosquitoes bite most around dusk and at night and breed in dirtier standing water, like storm drains, neglected pools and birdbaths. Culex species are the main carriers of West Nile virus.

Step 1: Remove Standing Water

Mosquitoes lay eggs in or near water, and some species can develop from egg to adult in about a week in warm weather. Walk your yard at least once a week, and after every rain:

  • Empty and scrub plant saucers, buckets, pet bowls and kids' toys.
  • Change birdbath water every few days.
  • Clean gutters and check that downspouts drain away from the house.
  • Drill drainage holes in tire swings and recycling bins.
  • Cover rain barrels with fine screen.
  • Keep pools circulating, and cover or drain unused hot tubs.
  • Fix low spots and leaky outdoor faucets that leave puddles.

Step 2: Make Your Yard Less Inviting

During the heat of the day, adult mosquitoes rest in shady, humid spots like dense shrubs, tall grass, ivy and under decks. Keep grass mowed, trim back overgrown plants and thin out ground cover near patios.

Step 3: Treat Where They Rest and Breed

Professional mosquito control focuses on two things:

  1. Barrier treatments applied to the foliage, fences and shaded areas where adults rest. This cuts down the number of mosquitoes biting in your yard.
  2. Breeding site treatment for water you can't drain, which stops larvae from becoming biting adults.

Because new mosquitoes keep flying in and hatching, treatments work best on a regular schedule through the warm season rather than as a single spray.

Protect Yourself Too

Use an EPA-registered insect repellent, follow the label, and wear long sleeves at dawn and dusk when mosquitoes are most active. Keep window and door screens in good repair.

After Heavy Rain

Expect a spike in mosquitoes about a week or two after big storms. Read pest control after rain and flooding to see what else to watch for.

Frequently Asked Questions

When is mosquito season in San Antonio?

Mosquitoes are usually active from spring through fall, and warm winter stretches can keep them going even longer.

How often should mosquito treatments be done?

Most yards need regular treatments through the warm season, often monthly, because new mosquitoes keep arriving and hatching.

Do citronella candles work?

They may help a little in a small area with no wind, but they don't replace removing standing water, repellent and treatment.
