Summer Larviciding

Larviciding Habitat

Mosquito Control staff will begin standing water treatment flooded woodlands in Midland County starting April 3rd. Please call the office at (989) 832-8677 if you have standing water.

Mosquitoes can be prevented by eliminating standing water producing mosquitoes or by treating aquatic sites with environmentally safe larvicides. To help prevent mosquitoes keep tires indoors or covered with a tarp so they won't hold water. Clean out wading pools, birdbaths, gutters and other water-filled containers.

Midland County Mosquito Control employees inspect and treat standing water to control mosquito larvae throughout the spring and summer. Some of the sites that may produce summer mosquitoes and the frequency of inspection are shown below.
