Mosquito Abatement

Town of Frederick Mosquito Control Program



The Town of Frederick Public Works Department is handling mosquito control activities. The Town utilizes a combination of Larvicide activities and Adulticide activities to try and mitigate the occurrence of West Nile Virus.

Public Works goes out and tries to identify possible breeding grounds and areas where mosquito larvae may thrive. Staff then applies larvicides to control the mosquitoes before they become adults.

Adulticide spraying occurs on an as needed basis based upon West Nile conditions (as shown on the County threat level), citizen complaints, and general need. Throughout the summer town staff will spray on either Tuesday or Thursday night after 7:00pm. Spraying cannot occur if the wind is 10MPH or over, or if there is inclement weather. Staff will make a judgment call on whether spraying can occur. Tuesday night sprayings will be in areas East of I-25 and West of Colorado Boulevard. Thursday night sprayings will be in areas West of I-25 and East of Colorado Boulevard. As of the week of August 8th, Town Staff will also start spraying on Wednesday evenings to hit areas that need it most, to make up for a weather delay from Tuesday or in anticipation of bad weather for Thursday.
