Precautions Encouraged as Mosquito Season Ramps Up in Austin

AUSTIN, Texas — Mosquito season is well underway in Austin and Travis County following recent rains. Now is the time to familiarize yourself with mosquito prevention strategies to protect yourself and others from diseases like the West Nile virus and Zika.

From spring to fall, when the weather is warmer and wetter, mosquitoes breed throughout Austin and the surrounding areas. While their bites are itchy and annoying, mosquitoes pose a much greater threat to people by spreading disease. Mosquitoes may carry diseases that contribute to infections such as Zika, West Nile virus, dengue fever, encephalitis and canine heartworm. 

“While we’re all getting ready to enjoy the summer, let’s be sure to bring mosquito repellent and appropriate clothing anytime we plan on spending time outdoors,” said Environmental Health Services Division Chief Marcel Elizondo. “We've consistently seen West Nile virus for years, and this year shouldn’t be any different. Taking time to protect yourself can keep you from getting sick or even needing to go to the hospital.” 

In 2025, 41 mosquito pools tested positive for the West Nile virus. Preliminary results, pending finalization by the Texas Department of State Health Services, show five West Nile virus cases were reported in Austin-Travis County.

Fight the Bite Day and Night with the Four Ds: 

• Dusk and dawn: Although different species of mosquitoes are active at different times of day, the species that spread West Nile virus are most active between dusk and dawn. 
• Dress: Wear pants and long sleeves when you are outside. Wear light-colored, loose-fitting clothing; mosquito-repellent clothing is also available.
• DEET: Apply an insect repellent containing DEET. Read and follow label instructions. Spray both exposed skin and clothing with repellent. Find the Environmental Protection Agency’s list of repellents here. 
• Drain: Remove standing water in your yard and neighborhood. Old tires, flowerpots, clogged rain gutters, birdbaths and wading pools can be breeding sites for mosquitoes.
