A high-pressure stream of 140-degree water is enough to cook a zebra mussel, not to mention blast it to bits.

With the Mobile Decontamination Machine at its side, the Wisconsin Department of Natural Resources is flexing its arm in the zebra mussel battle. Instead of relying on chemicals, bacteria or toxins covered in fat to manage the invasive species, the department is adopting a physical attack.
Hot water is pumped through boats’ bilge lines to kill and flush out the mussels, which often live in bilge water and the underside of the boats. When boats travel from lake to lake, they can deposit the mussels and spread the invasion.
But not anymore, if more boaters opt to have their boats sprayed with the Mobile Decontamination Machine. Maybe an edgier name, like the Mobile Mussel Destruction Palace would help drum up enthusiasm.

Most people have known for a long time that zebra mussels (especially their larval form) can be transported within boat bilges and motors. It’s just sad that the Michigan DNR was more concerned about protecting boaters “rights” to free access to some of our waters, instead of working to curtail the spread of zebra mussels. Some parts of the “Holy Waters” of the AuSable River are now contaminated with zebra mussels due to the unwillingness of the DNR to protect them.
