A Note from the Management

The Grand River Mosquito Control District provides the essential services of mosquito surveillance, inspections, and implementing control measures to reduce the spread of mosquito-transmitted diseases, such as West Nile Virus.  At this time, the Center for Disease Control and Prevention (CDC) has no data to suggest that the new coronavirus, which causes the disease COVID-19, is transmitted by mosquitoes or ticks.
