Mosquito Spray Scheduled for August 14

Clarke Mosquito Control will spray for adult mosquitoes on Monday, August 14, 2017, weather permitting. The spraying will begin at approximately 8:30 p.m. and all streets within incorporated Downers Grove will be complete by early dawn. Should weather interfere with operations, spraying will occur on Tuesday, August 15. Mosquito samples from traps monitored by the DuPage County Health Department have tested positive for West Nile Virus. As a result, surrounding communities will be spraying to reduce the adult mosquito population over the next several days.

 

Clarke will be spraying the EPA approved Anvil 10+10 with an ultra-low volume fogging machine mounted on the back of a truck. The active ingredient in Anvil 10+10 is a pyrethroid that emulates naturally derived insectisides 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.

The Village has been treating for mosquitoes by applying larvicides to catch basins and storm sewers to inhibit mosquito larvae from developing into adults. Recent rainy weather has created environmental conditions favorable for increased mosquito breeding. While most of the mosquitoes are the floodwater mosquito (Aedes vexans), which can be an aggressive but harmless daytime biters, conditions are also favorable for the house mosquito (Culex pipiens) to increase, which is the carrier of West Nile Virus. 

 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.
