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.
Ditch & Storm Sewer Treatments
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.
