The Chicago Department of Public Health (CDPH) is continuing its efforts against West Nile virus by spraying to kill adult mosquitoes. This is the first spraying of the season. Spraying will occur in parts of the Pullman and South Deering Community areas. Wards impacted include parts of the 7th, 8th and 10th wards. CDPH staff have been leaving door hangers in the affected areas to notify residents that the spraying will occur. The material being used to control the adult mosquitoes, Zenivex™, will be applied at a rate of 1.5 fluid ounces per acre. It is approved for use by the U.S. Environmental Protection Agency and is used to control mosquitoes in outdoor residential and recreational areas. While the spray is not harmful to people or pets and is routinely sprayed in residential areas across the nation, residents of targeted neighborhoods may choose to stay indoors and close their windows while spraying is underway, as an extra precaution. By utilizing data, the city is able to most efficiently target high-risk areas for the virus. CDPH reminds residents to take precautions against mosquitoes that may carry the virus, including:

• Use insect repellent that contains DEET, Picaridin or Oil of Lemon Eucalyptus.
• Eliminate standing water. 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.
