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. These are typically areas with standing water. Staff then applies larvicides in the form of pellets 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. Beginning Tuesday, May 22nd, town staff will spray on Tuesday and Thursday night 7 p.m. - 10:30 p.m. 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. Tuesdays and Thursdays are scheduled days for fogging. If more fogging is required Wednesdays and Fridays will be added. The entire Town will be completed every scheduled day.

The Public can do their part in the battle against mosquitos by eliminating sources of standing Water such as disposing of old tires, any type of containers that collect and hold water, Maintaining gutters, etc.  Pet dish and bird bath water should be changed every 2 days.
