Everything You Need to Know About Invasive Jumping Worms Found in Indiana
Worms are (Generally) Wonderful
Generally, worms are wonderful friends to have in your garden, but that just isn't the case with the invasive species of jumping worm recently discovered in Southern Indiana.
Good Worms, Bad Worms
You "average" worm - there are actually several different kinds including those that hang out in leaf litter, and those that burrow vertically into the ground - are really good for our ecosystem. In fact, according to the USDA, they add a number of vitamins and nutrients to the soil like nitrogen, phosphorous, and potassium. The USDA says worms,
- Improve soil stability, air porosity and moisture holding capacity by burrowing and aggregating soil;
- Turn soil over and may reduce the incidence of disease by bringing deeper soil to the surface and burying organic matter;
- Improve water infiltration by forming channels and promoting soil aggregation;
- Improve root growth by creating channels lined with nutrients for plant roots to follow.
The Indiana Department of Environmental Management recommends composting with worms and says you should let them eat your garbage.
They will turn the garbage into some of the best fertilizer on earth known as worm castings or vermi-compost. This is a fascinating, fun, and easy way to recycle your organic kitchen waste. Worm composting requires very little work, produces no offensive odors, and helps plants to thrive.
Invasive Jumping Worms in Indiana
While your average, run-of-the-mill worm is your friend in the garden, there is an invasive species that is not a friend but a foe. The invasive jumping worm has been found in parts of southern Indiana and according to experts at Purdue University, these garden pests will eat up all of the organic material at the surface of the soil. The waste left behind looks like coffee grounds and offers no nutritional value to plants. They also do not aid in air and water flow for the soil like regular worms do.
How Did Jumping Worms Get to Indiana?
These worms are not native to Indiana and they also do not migrate. That means that humans are primarily responsible for the jumping worms calling southern Indiana home. Experts say that the worms have likely found their way here through the transfer of soil, compost, or plants from other places.
How to Stop the Spread of Jumping Worms
Robert Bruner, Purdue Extension’s exotic forest pest specialist has been working with others at Purdue University to raise awareness, and encourage gardeners to refrain from sharing soil and compost. He also advises that the public avoid potted plants from unknown sources. There is also a process called solarizing that can be used to rid your soil of unwanted guests.
