CRYSTAL LAKE – The city again take will measures to control and reduce the adult mosquito population as a rain-filled summer nears its end. A citywide misting application will take place overnight between Tuesday and Wednesday. A rain date is scheduled for the next available night. Sprays typically take place once the city’s traps have reached a threshold of about 150 female mosquitoes, and occur between two and three times a summer, Public Works Director Michael Magnuson said. The city has an annual contract with Clarke Environmental Mosquito Management Inc.
