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. 

WHAT WE DO

Mosquito Control TruckThe City of Seabrook has one of the most aggressive mosquito control programs and consists of adulticiding (spraying/fogging) and larviciding (spraying standing water). Our staff routinely measures mosquito population levels to implement a fogging schedule best suited to combat the current population.

What We Use

The City of Seabrook uses a broad spectrum all-temperature, quick knockdown, low odor, and non-corrosive synergized synthetic pyrethroid insecticide for the control of adult mosquitoes in residential, recreational, and other areas. This same product can also help control biting and non-biting midges and black flies. Download the MDS.

Mosquito Spraying Schedule

Seabrook abides by the requirements of the products' label guidelines and the laws set forth by the Texas Department of Agriculture. The mosquito spraying schedule is dependent on current blooms (population level) and is weather-dependent to ensure affectability.

Where We Spray

The City of Seabrook's Mosquito Control is only able to fog areas within the public right-of-way, and not within private property.

When We Spray

Seabrook's permit allows for fogging during evening hours and into the morning. We are not permitted to spray during the daytime.

We are also mindful of pollinators and do not fog during hours of heaviest pollinator activities or near registered bee colonies.

Mosquito spraying will not occur while it is raining, or if sustained wind speeds are over 10 miles per hour.


HOW YOU CAN HELP

While the City does everything it 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.

Zika Virus

  • Zika is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus).
    • These mosquitoes bite during the day and night.
  • Zika can be passed from a pregnant woman to her fetus.
    • Infection during pregnancy can cause certain birth defects.
  • There is no vaccine or medicine for Zika.
