Mosquito Spray On Thursday, September 8, 2022

Mosquito Graphic

Clarke Mosquito Control will spray for adult mosquitoes on Thursday, September 8, 2022, weather permitting. Mosquito samples from traps in Downers Grove and neighboring communities have tested positive for West Nile Virus. To reduce the potential public health risk of mosquito borne illness, the Village and surrounding communities are spraying to reduce the adult mosquito population.

Spraying will begin at approximately 8:00 p.m. and all streets within incorporated Downers Grove will be completed by early dawn. The Village has also been treating mosquitoes by applying larvicides to catch basins and storm sewers to inhibit mosquito larvae from developing into adults.

Clarke will be spraying the EPA approved DUET with an ultra-low volume fogging machine mounted on the back of a truck. The active ingredient in DUET is a pyrethroid that emulates naturally derived insecticides found in chrysanthemum flowers. It is recommended that residents keep doors and windows closed while spraying is being done. Residents with questions or those requesting advanced notification of sprayings should contact Clarke Mosquito Control directly at the hotline number, 1-800-942-2555.

Residents are reminded to take the following precautions regarding mosquitoes:

  • Minimize time spent outdoors between dusk and dawn when mosquitoes are the most active.

  • When outside between dusk and dawn, wear loose-fitting, light-colored clothing that includes long pants, long-sleeved shirts, socks and shoes.

  • Apply insect repellents containing DEET, Picaridin or oil of lemon eucalyptus to exposed skin and clothing.

  • Make sure that doors and windows have tight fitting screens.

  • Remove containers that may hold water to eliminate standing water which serves as a breeding ground for mosquitoes, i.e., discarded tires, cans, ceramic pots.

  • Change water in bird baths at least once per week, and drain and replace water in children's backyard wading pools every four to five days.

  • Make sure that rain gutters, downspouts, swimming pools and pool covers are free of standing water.

  • Keeping grass and weeds cut short to eliminate hiding places for adult mosquitoes.
