A Village-wide mosquito spraying was conducted on August 18, 2010 to reduce the adult mosquito population. Recent 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 biter, conditions are also favorable for the house mosquito (Culex pipiens) to increase, which is the carrier of West Nile Virus.
West Nile Virus has been detected by the DuPage County Health Department in mosquito batches in and around Downers Grove. Concerns about dead crows or other birds should also be directed there.
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.
- Keep grass and weeds cut short to eliminate hiding places for adult mosquitoes.
