tu suggests that in order to not "move a mussel" from one water body to the next, follow this outline:
*State owned boat launch sites have a hose-off area for your use. The states that impose regulations, i.e., Nevada, must then furnish a method for felt soles, boats, trailers and toy haulers to be hosed off before leaving the recreation area.
*Boot laces, tongues and inner soles are also suspect.

Don't kid yourself though. It takes water temps of 140 degrees to kill invasives which are transportable from one lake/river to the next. Mere hosing off with hot, soapy water doesn't kill:
*the New Zealand mud snails
*quagga mussels

Here's what I do. I have a thick .06mil water-tight plastic bag to encase my felts right there at the river. When I get home, I bring the tea kettle to a boil. While I'm waiting for the water, I'll take Formula 409 to the laces, tongue and felts of the boots. I have a plastic container large enough for both boots to sit in upright, filled with the boiling water, to the level where the felt is stitched and glues to the upper.

The glue that holds the wading boots has not failed because of the high temp water. Besides, if they leak, isn't that what they are designed to do?

tu also recommends cleated rubber soles. But that's an entirely different discussion.
