Migratory bird hunters in Wisconsin are being urged by the Department of Natural Resources (DNR) to help prevent the spread of aquatic invasive species during the fall hunting season. The DNR highlights that actions taken by hunters at boat launches and access points are crucial for protecting wetlands and waterways.

According to the DNR, mud attached to boots or equipment can carry seeds, plant fragments, and small organisms that may be invasive. Water remaining in boats, decoys, or motors could contain zebra mussel larvae or pathogens. Hunting dogs may also transport invasive species when seeds, snails, or insects become trapped under their vests or in their fur. The department advises rinsing and brushing off dogs after hunts to reduce this risk.

The faucet snail is identified as a particular concern for migratory bird hunters. These snails carry parasites harmful to ducks and other waterfowl and have been associated with significant bird deaths in the Upper Midwest. The DNR stresses the importance of preventing their spread to maintain healthy hunting areas.

Hunters seeking more information on stopping faucet snails and other aquatic invasive species can consult resources on the DNR’s Invasive Species Prevention webpage or visit the “Hunter Resources” section on its Waterfowl Hunting webpage.

The DNR recommends several steps for hunters before entering and leaving any waterbody: inspect waders, boats, trailers, motors, gear (including boots, blinds, and dogs); remove all plants, animals, and mud; drain water from equipment; avoid moving live fish or plants between waterbodies; and remove seed heads and roots from vegetation used in duck blinds. It is illegal to use phragmites for camouflage in counties where it is classified as a Prohibited species under NR 40 regulations—a designation that includes western Wisconsin.

"Protect the places you love to hunt – for this season and generations to come. With just a few extra minutes of care, hunters can help stop invasive species in their tracks and keep Wisconsin’s wetlands and waterways thriving," stated the DNR.
