Mosquito Control

The City of Ashland will once again be spraying for mosquitos in the City Parks, balancing the need for mosquito control, along with the diseases they can carry, with the needs for keeping the use of insecticides to a minimum and controlling costs. The plan is to apply an insecticide through fogging in Brookside, Brookside West, and Cahn Grove Parks utilizing the services of an area contractor. The parks will be fogged after dusk, beginning at approximately 9:30 pm, on scheduled dates. The fogging method is especially effective since the insecticide connects with the underside of leaves where adult mosquitoes generally land at night. 
As the summer progresses, the Ashland City-County Health Department and the Mayor's office will continue to monitor the effectiveness of the fogging and to evaluate the need in other areas of the city. Mosquito traps will be used to track the types of mosquitoes and the diseases which they may be carrying. Mosquito dunks will be placed in areas of standing water to disrupt the life-cycle and reproduction of mosquitoes. To find out more about the insecticide used, please see the insecticide label below.
The mosquito control application uses a combination of a truck equipped with the fogger and a smaller utility vehicle. The use of the utility vehicle allows fogging around the perimeter of the parks and the tree lines with minimum impact to the fields and grass areas. This approach also allows the insecticide to be applied closer to the leaves where the adult mosquitoes like to hide. 
Aug. 29, 2018 Update: After receiving notification from the Ashland County Health Dept. regarding the positive pools of mosquitoes that were found in the 11th Street area of the City of Ashland, the area will be fogged for mosquitoes on Thursday, August 30.

Adultacide (Fogging) - Targets the adult mosquitoes

Mosquito Traps
- Set around the City and County of Ashland, the traps allow the Health Dept. to monitor the types of mosquitoes in our area and the diseases which they are currently carrying. 

- Dunks are placed in standing bodies of water where they slowly release a bacterium which is eaten by the mosquito larvae. The dunks last about 30 days in the water but have long-term effects as they kill mosquitoes in their developmental stages.
