Invasive "Earthworms on Steroids" Threaten Gardens in NE Wisconsin

Invasive jumping worms, also known as "earthworms on steroids," are a species of worm that moves like a snake, thrashes around, jumps into the air, and sheds its tail to escape. Originally from eastern Asia, these worms have infiltrated over 30 states in the U.S. and parts of Canada. They eat organic matter in soil, leaving behind waste that alters the soil's texture and composition, making it inhospitable for native plants. In addition, the worms can accumulate toxic metals that can negatively impact birds that feed on them. To prevent the spread of jumping worms, people are encouraged to educate themselves, clean soil and debris when moving it, and only purchase plants and gardening materials believed to be jumping worm-free. If found, the worms should be removed and destroyed, and measures such as high temperatures or covering soil with clear plastic can help eliminate them.
