Houston's wet spring and summer climate creates ideal conditions for Aedes aegypti and other mosquito species. Professional barrier spray reduces adult populations by up to 90%, but eliminating breeding sites is the foundation of effective mosquito control.
1. Eliminate Standing Water
Aedes aegypti mosquitoes can lay eggs in as little as a bottle cap of standing water. Walk your yard after every rain and eliminate: clogged gutters, flower pot saucers, birdbaths (change water weekly), children's toys that collect water, low-lying tarp folds, and trash can lids. Any container that holds water for more than 72 hours is a potential breeding site.
2. Trim Vegetation and Maintain Your Yard
Adult mosquitoes rest in shaded areas during the day — dense shrubs, overgrown grass, wood piles, and shaded fence lines are prime harborage areas. Keep grass mowed, trim shrubs, and remove brush piles.
3. Treat Standing Water That Cannot Be Eliminated
Some water features cannot be eliminated — ornamental ponds, rain barrels, drainage ditches. Use larvicide donuts (Bti) which kill mosquito larvae without harming pets, birds, or fish.
4. Install or Repair Window and Door Screens
Mosquitoes enter homes through gaps of 1/16 inch or larger. Repair or replace any torn window screens and install door sweeps.
5. Create Airflow with Fans
Mosquitoes are weak fliers. A strong fan on your patio or porch creates airflow that significantly reduces mosquito activity in that zone.
6. Use EPA-Registered Personal Repellent
When spending time outdoors during peak mosquito activity (dawn and dusk for most species, daytime for Aedes aegypti), use EPA-registered repellents containing DEET, picaridin, or oil of lemon eucalyptus.
7. Schedule Professional Barrier Spray
Professional barrier spray treatments reduce adult mosquito populations by up to 90% and last 3–4 weeks. Monthly service provides continuous protection through Houston's peak mosquito season (April–October).
8. Consider a Misting System for Large Properties
For Houston properties with large yards, pools, or adjacent greenbelts, automated misting systems deliver scheduled treatments at dawn and dusk.
