About Us

Grand River Mosquito Control District

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.

Mosquitoes love water and can breed in even tiny amounts of H20. It’s important to survey your property weekly and drain any standing water.

  • Dump or Drain Tires
  • Change the Water in Birdbaths at Least Once/Week
  • Empty & Clean Pet’s Water Bowls Weekly
  • Clean Out Troughs & Gutters
  • Turn Over or Remove Empty Pots
  • Protect Boats & Vehicles from Rain with Tarps so that Water Doesn’t Accumulate
  • Empty Swimming Pool Covers of Water & Drain Plastic Pools when Not In Use
  • Plug Tree Holes
  • Discard Empty Cups & Containers

Follow the 3 D’s


If you must be outside when mosquitoes are active, cover up. Wear loose fitting, light colored clothing. Studies have shown mosquitoes are more attracted to dark clothing and can even bite through tight-fitting clothes. Wear shoes, socks, long pants and long sleeves.

Wear Mosquito Repellent

Apply mosquito repellent to bare skin and clothing. Always use repellents according to the label. Repellents with 10-30 percent DEET, picaridin, oil of lemon eucalyptus and IR3535 are effective.


Use mosquito netting to protect children younger than 2 months old.

Cover Doors & Windows with Screens

Keep mosquitoes out of your house. Repair broken screening on windows, doors, porches and patios.
