The Grand River Mosquito Control District works to suppress mosquito populations within the boundaries of the district, and in an environmentally responsible manner. We consistently monitor both larval and adult mosquito populations to organize the population statistics, to evaluate organizational efforts and to plan control strategies.

Beginning in mid-April through September, our field technicians treat mosquito-breeding sites on 2500 private properties, as well as public properties. The most effective way to control mosquito populations is through the treatment of standing water at these sites before the mosquitoes mature into flying adults.
