EAST BAY TOWNSHIP, Mich. (AP) - Federal agents are going after one of the Great Lakes' greatest invasive pests this week when they use poison to kill the larvae of sea lamprey in a stream feeding into Lake Michigan.

The Traverse City Record-Eagle says the U.S. Fish and Wildlife Service plans treatments for Tuesday through next Sunday in the Mitchell Creek stream bottom. The creek flows through Traverse City State Park before entering Grand Traverse Bay's east arm.

The park is in Grand Traverse County's East bay Township, east of Traverse City.

Wildlife service fish biologist Alex Gonzalez says the treatments are 95-99 percent effective in killing the parasite at its most vulnerable stage.

Lamprey have been sucking the blood of lake trout, salmon and walleye for decades.
