Joliet Township Government implemented a mosquito control program many years ago.  The Township, in conjunction with the City of Joliet and the Village of Rockdale, has a contract with Clarke Environmental Mosquito Control to provide scheduled applications of safe and effective mosquito control for the comfort and health of our residents.  With the outbreak and spread of the West Nile Virus, we believe it is even more imperative to provide the necessary control of the mosquito population in Joliet Township.  To obtain information regarding the mosquito control application, such as dates of applications or to report excessive mosquito problems, please contact the Clarke Mosquito Company hotline toll free at (800) 942-2555.
