ST. LOUIS, Mo. (KTVI) — An invasive species of worm has wriggled its way into Texas
“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.
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 the following states:
The University of Illinois says the worms can’t survive past frigid winters, 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.
