Larval control operations are underway for the season. Crews will be applying Bti, a biological larvicide, to control mosquito larvae in irrigated and wetland areas in and around Laramie. Bti is non-toxic to birds, mammals, amphibians and fish and only affects the immature stages of mosquitoes and blackflies. Phone the ‘HOTLINE” at 721-5056 to hear a recorded message detailing any IPM or mosquito control applications. The message is updated daily at 4pm for that evening and the following day. To report a standing water source, or to access other information about the Mosquito Control program please visit the City webpage at www.cityoflaramie.org or contact, Mosquito Control at 307-721-5258.
