Jumping worms are invading Wisconsin. Scientists have discovered a way to slow them down.

It’s time to bring the heat — literally.

Researchers at the University of Wisconsin-Madison have determined that heat can kill the cocoons of jumping worms, the invasive earthworms that have spread dramatically throughout the state in recent years.

While the full ecological impact of these wriggly invaders is not fully known, research suggests they can significantly alter the soil structure in an infested area — and potentially all that grows there.

The new UW study offers a potential new way to slow their spread.
