Mosquito Control

Lake County Mosquito Control

SPRAY SCHEDULE HOT LINE 350-2088 OR 918-2088


The Lake County General Health District sprays most of the municipalities in Lake County that are densely populated. Spraying is done in the county to reduce the risk of mosquito borne diseases and to provide for a more comfortable summer environment. Since mosquitoes infected with both La Crosse and St. Louis Encephalitis Virus, and human cases with this disease have, in the past, been identified in the Health District, mosquitoes can be considered a “public health nuisance. The public health significance of mosquitoes has been amplified by the resent spread of the West Nile Virus.”

Included in this web site is the latest spray schedule, materials that are used by the health district, (including msds and labels), reasons spraying may be canceled and some other related mosquito links. The Health District is licensed through the Ohio Department of Agriculture to apply pesticides for the use of mosquito control. If you have any further questions that are not answered from this web site, please contact our offices weekdays between 8:00 a.m. and 4:30 p.m. at 440-350-2543 or 440-918-2543
