Invasive Snail Appears To Be Spreading In Wisconsin

Invasive snails that can lead to the death of waterfowl have been found in a cold water stream in Wisconsin.

The faucet snail is already in the Great Lakes and some larger rivers. But, it’s now been found in a stream in Langlade County. The discovery is important because waterfowl also frequent smaller streams, and the faucet snail can carry parasites that can kill the birds when the snails are eaten.

Bob Wakeman, the water resources management specialist for the state Department of Natural Resources, said they’re asking boaters, anglers and waterfowl hunters for help to keep the snails out of more waterways.

“Before they leave a body of water, clean off your gear, drain your water, and that’ll help prevent the spread,” he said.

Wakeman acknowledges that ducks and coots can also spread the parasite by passing the organism out of their bodies while other birds are swimming and eating nearby. He also said faucet snails can out-compete native snails for food.
