GEORGETOWN TOWNSHIP, Mich.—While many Michiganders are trying to repel bugs this summertime, the Ottawa County Parks and Recreation Department is welcoming thousands of weevils to the waters of Grand River Park.
The weevils are being used to attack the invasive Eurasian watermilfoil, which has spread across the park’s small lake. Biological experts from Michigan State University say the aquatic plant can impact fish habitats and deter recreational activities on the water. Ottawa County Parks says weevils are safer and more effective than chemicals in attacking milfoil, and park visitors will likely never realize their presence.
The parks and recreation department recently began using goats to curb invasive plants at Bur Oak Landing in Coopersville and Riverside Park in Grand Haven.
