This video provides information on the ecology of two aquatic invasive species, Didymo and New Zealand mudsnails, and importantly, an easy-to-follow step by step protocol on how to decontaminate waders and other angling gear using Formula 409.

This protocol was based on the results of the peer-reviewed journal article: "Simultaneously Decontaminating Angling Gear for New Zealand Mudsnails (Potamopyrgus antipodarum) and Didymo (Didymosphenia geminata): a Comparison of Two Chemical Approaches" that was published in 2025 in the journal North American Journal of Fisheries Management and was authored by: Nicole Wagner, Hailee Mersino and Scott Tiegs in the Department of Biological Sciences at Oakland University, and Jeremy Geist of Trout Unlimited. This video was made possible by a State of Michigan grant to Wagner and Tiegs through the Michigan Invasive Species Grant Program.

"Sarah was wonderful to work with across all aspects of our project from its initial development, to helping ensure that the final product reached our targeted audience. She excels at clear communication, and it's abundantly apparent that she loves what she does. The final product, a short instructional video, exceeded my expectations and I attribute the overall success of the project to Sarah's talents and effort." - Scott Tiegs
