Mosquito Season in Texas: What to Expect in March
Why Are Mosquitoes Active in March?
Mosquito activity in Texas depends on temperature, humidity, and standing water. By March, the weather starts warming up, creating ideal conditions for mosquito populations to surge. Some key factors include:
Rising Temperatures: Mosquitoes become active when temperatures consistently reach 50°F or higher. In many parts of Texas, March brings daytime highs in the 60s and 70s—perfect for mosquitoes to emerge.
Spring Rainfall: March often brings increased rainfall, leading to more standing water—mosquito breeding grounds. Even small amounts of water in clogged gutters, flower pots, or birdbaths can support mosquito larvae.
Longer Days: As daylight hours increase, mosquitoes have more time to feed and reproduce.
Common Mosquito Species in Texas
Texas is home to over 80 species of mosquitoes, but the most common in March include:
Aedes aegypti (Yellow Fever Mosquito): Known for spreading Zika, dengue, and chikungunya, this mosquito prefers urban areas and is active during the day.
Aedes albopictus (Asian Tiger Mosquito): Another daytime biter, this species is aggressive and thrives in backyards.
Culex quinquefasciatus (Southern House Mosquito): This species is most active at night and is a primary carrier of West Nile virus.
How to Protect Yourself from Mosquitoes
While we can’t eliminate mosquitoes entirely, there are steps you can take to reduce their numbers and avoid bites:
1. Eliminate Standing Water
Dump out water from buckets, birdbaths, flowerpots, and pet bowls at least once a week.
Keep gutters clean to prevent water buildup.
Fix leaky outdoor faucets and ensure proper drainage around your home.
2. Use Mosquito Repellents
Apply EPA-approved repellents containing DEET, picaridin, or oil of lemon eucalyptus when spending time outdoors.
Wear long sleeves and pants, especially in the early morning and evening when mosquitoes are most active.
3. Protect Your Home
Install or repair window and door screens to keep mosquitoes out.
Use fans on patios or porches—mosquitoes struggle to fly in strong air currents.
4. Consider Mosquito Control Solutions
If mosquitoes are a major problem in your area, consider hiring a professional mosquito control service.
Natural predators like dragonflies, bats, and certain fish species can help keep mosquito populations in check.
Looking Ahead: Peak Mosquito Season
While March marks the beginning of mosquito season, peak activity typically occurs in the summer months when heat and humidity reach their highest levels. Taking early precautions now can help keep mosquito populations lower as the season progresses.
By staying proactive, Texans can enjoy the beautiful spring weather without becoming a feast for these buzzing pests. Stay safe, stay prepared, and keep those mosquitoes at bay!
