Stop the spread of spiny water flea.

Stop Spiny Campaign Resources

Swedish dishcloths

As part of the Stop Spiny campaign, we developed a design that can be printed on cloths to remind boaters and anglers to wipe down their equipment before leaving a spiny water flea-infested lake. MAISRC printed a large number of cloths in the fall of 2020. If you are interested in distributing the cloths to anglers near you, or through your lakeshore association, etc., please send a request to Meg Duhr, MAISRC Outreach Specialist at mduhr@umn.edu. You are welcome to print and use all designs linked on this page at no cost, but we ask you leave MAISRC's logo on all materials.
