Mosquito Control

The mosquito season is weather-related and usually starts when the weather gets warmer and the rainy season arrives around April and can last up until December. The City of Seabrook has one of the most aggressive mosquito control programs and consists of adulticiding (spraying / fogging), larvaciding (spraying standing water) and implements the fogging according to mosquito population levels.

Resident Responsibility

While the City does everything they can to control the mosquito population by spraying the right-of-ways as needed, there are several things YOU can do to help also;

  • Get rid of standing water on your property where mosquitoes might breed.
    • flower pots, tires, cans, buckets, plastic children's toys, tarps, etc.
  • Keep gutters clean and free-flowing
    • Standing water in gutters can breed mosquitoes.
  • Keep swimming pools, spas, and fountains properly treated with chemicals.

It usually takes ten days following a plentiful rain for mosquito larvae to develop into mosquitos. Visit Harris County Public Health and Environmental Services for more information about mosquito control and education programs in Harris County. For additional questions, please call 281-291-5722.
