Invasive ‘jumping worms’ spreading through several US states, spotted in Kansas

Local News

TOPEKA, Kan. (KTVI) — An invasive species of worm is wriggling its way into the Midwest, including in Kansas.

“Jumping worms” (Amynthas spp) thrash wildly when handled, are 4 to 8 inches long, move quickly like a snake and can shed their tails when threatened.

In Kansas, the department of parks, wildlife and tourism said they have been documented at Tuttle Creek State Park and a farm in Kansas City, but a formal survey hasn’t been completed.

The state entomologist at the Kansas Department of Agriculture, Taro Eldredge said officials are not going to put any restrictions in place to contain the spread of the worm as of right now.

“Keep gardening as you are, and when you see some issues, there’s some great online resources, but unfortunately the science is currently lagging in terms of what do we do once we get them,” said Eldredge.

He said the state will be watching what other states with higher numbers of worms are doing to see if anything can happen in Kansas.

The jumping worms originally come from Asia and were officially found in the Midwest by the University of Wisconsin at Madison in 2013. Researchers have been tracking their movements since then. They may have been brought to the United States as fish bait.

The worms can be found in the top few inches of soil, leaves, or mulch, and they are displacing earthworms, centipedes and other animals. They also damage plant roots, deplete nutrients, and alter the water-holding capacity of the soil. Plants become more susceptible to pests, drought and disease. The worms are a danger to agriculture, gardens and forests.

The jumping worms were more common on the East and West Coasts of the United States. Now the worms have been spotted in Midwestern states such as Missouri, Illinois, Iowa, Kansas, Nebraska, Oklahoma, Texas, Louisiana, Indiana, Minnesota, Indiana, Ohio, Kentucky and Tennessee.

The University of Illinois says the worms can’t survive past frigid winters of the upper Midwest. But, they have egg casings that will persist through the cold weather.

The Missouri Department of Conservation is asking anyone who finds jumping worms to kill them.

University of Illinois Horticulture Educator Nicole Flowers-Kimmerle has outlined steps to help stop the spread of the worms:

  • Thoroughly clean tools, shoes, and vehicles when moving from one site to another.
  • Only purchase compost, mulch, or other organic matter that has been heated to appropriate temperatures and duration to reduce the spread of pathogens, insects, and weeds. Jumping worm egg casings do not survive temperatures over 104 degrees F.
  • Remove adult jumping worms. Place adults in a plastic bag and leave in the sun at least 10 minutes. Dispose of the bag in the trash.
  • Remove soil from all plants before transporting them
  • Wash roots by completely submerging plant roots in water and washing away remaining soil.  Water is enough to remove soil and other materials from the roots.
  • Buy bare-root plants when possible.
  • Do not buy jumping worms for bait, vermicomposting or gardens.
  • Follow Plant Sharing Best Practices
