A wanted poster offers a reward for the capture of zebra mussels, an invasive species last seen in lakes George and Champlain that has taken over lakes, clogged water pipes, and made beaches stinky. Zebra mussels are small, triangular, and black or brown with white stripes. Control methods include drying boats in the sun for 3-5 days or putting mussels in rubbing alcohol to clear and clean lakes.
