(U//FOUO) In early May of 2010, Fort Wayne – Allen County Department of Health began preparing for the start of mosquito season. The department began asking residents to help control and prevent the spread of the virus by taking proper precautions to help eliminate possible breeding grounds for mosquitoes which spread the virus. The department will begin spraying areas for the virus after an adult mosquito has tested positive for the virus. The department will be using a new water based adulticide known as AquaAnvil and will spray a 1/2 mile radius around the site of the infected area. The health department is also providing residents with mosquito-eating fish. The minnows are a popular way to reduce mosquito larvae in backyard garden pools and ornamental ponds. The minnows however may not be released into creeks, lakes, rivers, or other natural waterways where Indiana game fish may be present. (Verbatim: Mosquito, West Nile season begins, 2010)
