May–November
Austin’s most active mosquito season typically runs through the warmer months.
Austin mosquito alert
West Nile virus is in Austin’s mosquito population. Here’s how to respond.
Austin Public Health confirmed a West Nile-positive mosquito pool in Travis County as seasonal mosquito activity climbed. That does not mean a human case occurred—but it is a clear reminder to reduce bites, remove breeding water, and take persistent mosquito activity seriously.

The short version
What Austin homeowners should know now
Detected locally
A West Nile-positive mosquito pool was reported in Travis County’s 78733 ZIP code.
Not a human case
A positive mosquito pool means the virus is present locally—not that a person was diagnosed.
Layer your protection
Reduce bites, drain water, and add professional control when mosquito pressure stays high.

Why activity surges
Austin mosquito pressure can rise quickly
Warm weather, recent rain, shaded landscaping, clogged gutters, plant saucers, toys, and other small water-holding areas can create breeding conditions close to home. Austin Public Health notes that mosquitoes are present year-round in Central Texas, with populations typically largest and most active from May through November.
Culex mosquitoes—the type associated with West Nile transmission—are especially active between dusk and dawn. Even when daytime conditions feel hot or dry, hidden water and protected areas can keep mosquito pressure going around a property.

Public-health checklist
Use the Four Ds every week
These practical steps come from Austin Public Health and CDC prevention guidance.
Dusk and dawn
Limit exposure when West Nile-vector mosquitoes are most active. If you are outside, add repellent and protective clothing.
Dress
Wear long sleeves, pants, and light-colored, loose-fitting clothing when practical.
Defend
Use an EPA-registered insect repellent and follow the label. Preventing bites is the best personal protection against West Nile.
Drain
Empty standing water weekly. Check saucers, birdbaths, toys, bowls, buckets, tarps, tires, rain barrels, and gutters.
Important context
The CDC says there is no licensed human vaccine or preventive medicine for West Nile disease. Preventing mosquito bites is the best personal-protection strategy.
When the basics are not enough
Persistent mosquitoes may point to hidden pressure around your yard
If mosquitoes are still taking over after you remove standing water, the property may include shaded resting zones, dense vegetation, drainage trouble, or breeding areas that are easy to miss.
Austin Pest Control starts with a free inspection and builds a mosquito-control plan around your property. Professional treatment can help reduce mosquito activity and make patios, play areas, and gathering spaces more usable. It works best alongside the Four Ds—not as a replacement for repellent, protective clothing, or weekly water removal.
Your next step
Start with a yard-specific inspection
- Review water-holding areas and drainage trouble
- Identify shaded resting zones and high-use outdoor spaces
- Recommend a tailored mosquito-control plan
- Combine professional service with weekly prevention habits
No outdoor treatment can eliminate every mosquito or guarantee disease prevention.

Common questions
West Nile virus and mosquito control
Does a positive mosquito pool mean someone in Austin has West Nile?
No. It means West Nile virus was detected in a tested group of mosquitoes. Austin Public Health’s June 30, 2026 update reported the positive pool and stated that no human cases had been identified at that time.
Can mosquito treatment prevent West Nile virus?
No mosquito-control service can guarantee disease prevention. Professional control can reduce mosquito activity around a property and should be combined with repellent, protective clothing, screens, and standing-water removal.
When is Austin mosquito season?
Austin Public Health says mosquitoes are present year-round, but populations are typically largest and most active from May through November.
What should I do if I feel sick after mosquito bites?
