The city sprays for mosquitoes on Friday nights, based on need, during the months of May through October. Spraying will start each evening at approximately 9 p.m. The City regularly uses an EPA - approved adulticide application called Kontrol 30-30 with a once a month rotational application of Fyfanon to combat chemical resistance.
In addition to mosquito spraying, the city treats drainage ditches and the storm sewer system (areas of standing water) with Environmental Protection Agency-approved Altosid briquettes. This is the most effective approach in reducing the mosquito population by preventing the mosquito larvae from becoming an adult mosquito. The larvacide program map shows the zones throughout Sugar Land that will be treated with Larvacide Pellets.
The city currently traps and tests mosquitoes for both the West Nile and Zika Viruses. Traps, as pictured below, are set up at multiple locations around the city.
