NORWOOD PARK — City crews will spray parts of Norwood Park, Portage Park and Dunning Wednesday in an effort to kill mosquitoes that may be carrying the West Nile Virus, officials said.
Spraying is scheduled to begin at dusk and continue until approximately 1 a.m., with licensed mosquito abatement technicians in trucks dispensing an ultra-low-volume spray of Zenivex, a chemical approved by federal officials to control mosquitoes in residential areas.
"When our mosquito traps indicate that the West Nile virus may pose health risks in a community, we take action quickly," said Chicago Department of Public Health Commissioner Dr. Julie Morita.

While the spray is not harmful to people or pets, residents of Dunning, Portage Park and Norwood Park may choose to stay indoors and close their windows while spraying is underway as an extra precaution, city officials said.
A resident of Skokie was diagnosed several weeks ago with the disease, officials said. No cases have been identified in the city, officials added.
Last year, state health officials reported 44 human cases of West Nile Virus in Illinois, including four deaths.
City health officials recommend people concerned about contracting West Nile from mosquitoes:
• Use insect repellent that contains DEET, Picaridin or Oil of Lemon Eucalyptus;
• Eliminate standing water near their home. This includes emptying water from flowerpots, gutters, pool covers, pet water dishes and birdbaths regularly;
• Keep grass and weeds short to eliminate hiding places for adult mosquitoes;
• When outside between dusk and dawn, wear loose-fitting, light colored clothing including long pants, long sleeve shirts, socks and shoes;
• Check that all screens, windows and doors are tight-fitting and free of holes and tears;
• Check on neighbors regularly who may need additional assistance, including the elderly.
