Jumping Worms

INVASIVE SPECIES ALERT: Jumping Worms

Jumping worms (Amynthas spp.) are an invasive species native to eastern Asia. In Minnesota, they harm forest ecosystems, yards, and gardens by disrupting soil structure and reducing plant growth.

Stop the spread by following this advice from the University of Minnesota Extension ⬈:

  • Don’t buy worms advertised as jumping worms, snake worms, Alabama jumpers, or crazy worms for any purpose.
  • Anglers: Dispose of unwanted bait worms in the trash. Never release any worm into the environment — all earthworms are non-native in Minnesota.
  • Gardeners: Be on the lookout for jumping worms in soil, potted landscape plants, mulch or compost. If you see soil that looks like coffee grounds or notice unusually jumpy worms in your mulch:
    • Don’t move any material that might be harboring jumping worms.
    • Report suspected jumping worms using EDDMaps ⬈ or report to the MnDNR ⬈ (look in "Reporting" section).
  • Composters: If you purchase worms for composting, know how to identify the species you are buying. Make sure your order doesn't contain jumping worms.
  • When enjoying nature, follow the recommendations of PlayCleanGo: Stop Invasive Species in Your Tracks ⬈
    • REMOVE plants, animals, and mud from boots, gear, pets and vehicles.
    • CLEAN your gear before entering and leaving a recreation site.
    • STAY on designated roads and trails.
