Wet Weather Breeds Mosquitos

A particulary wet month of May has prompted concerns about the population of the floodwater mosquito. A press release issued by the Illinois Department of Public Health, advises that while floodwater mosquitoes can be a nuisance, they are rarely infected with West Nile virus (WNV).

The Village's  Public Works Department administers the mosquito control program in Downers Grove. Mosquito levels are monitored and environmentally friendly products are used to reduce mosquito larvae development.

Residents should take the following precautions regarding mosquitoes: 

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