As the common name suggests, Asian jumping worms (Amynthas spp.) seem to jump or thrash when handled. Little kids and worm lovers might be excited by a find like this in their lawn, garden or woodlot but finding this worm is not beneficial for the native environment.

Why Jumping Worms Are A Problem
Most worms that you find in the Midwest are European and Asian non-natives. Both of these non-native types alter the native environment, although Asian jumping worms do it at a more alarming rate.  Jumping worms grow twice as fast, reproduce more quickly, and can work through organic debris much quicker than other worms. These invasive worms can severely damage the roots of plants in nurseries, gardens, forests, and turf. In areas of heavy infestation, native plants, microorganisms and animals such as salamanders may decline.

Asian jumping worms are an annual species; the adults die after the first freeze. But the cocoons, which are about the size of a mustard seed and resemble small pieces of dirt, will survive the winter and hatch when temperatures reach 50°F for a consistent period. These self-fertilizing worms do not need mates and can produce cocoons on their own. Because populations can grow faster than the common European species, they may out-compete existing worm populations. Cocoons can be spread easily in potted plants, on landscaping equipment, mulch, tire treads, and even hiking boots.
One telltale sign of an infestation is a very uniform, granular soil created from worm castings that are commonly said to look like coffee grounds. When you scratch the top layer of soil you will see the worms thrashing about with an erratic, snakelike movement. These worms, which can reach 6 inches in length, are much more active than European nightcrawlers. The Asian jumping worm can be found on the soil surface and in the leaf litter, making them easy to find. They can live anywhere from urban parks and suburban backyards to rural forests. You are also very likely to find them in compost piles and along roads.

Earthworm species have a body part called the clitellum where egg cocoons are produced. The Asian jumping worm has a prominent clitellum that completely encircles the body, is milky white to light gray, and is flush with the body; the body looks metallic. On European nightcrawlers, the clitellum is raised or saddle-shaped and reddish-brown in color and does not wrap entirely around the body.

Management
There is no magic control for these worms once they are found in soil. Asian jumping worms can now be found in the East, Mid-Atlantic, Midwest, and some Northwestern states. Prevention is the best way to keep them from being introduced to new areas. According to Wisconsin Department of Natural Resources, the following steps will reduce the spread of jumping worms:

• Educate yourself and others to recognize jumping worms
• Watch for jumping worms and signs of their presence
• Arrive clean, leave clean. Clean soil and debris from vehicles, equipment and personal gear before moving to and from a work or recreational area – they might contain jumping worms or their cocoons
• Use, sell, plant, purchase or trade only landscape and gardening materials and plants that appear to be free of jumping worms
• Sell, purchase or trade only compost and mulch that was heated to appropriate temperatures and duration following protocols that reduce pathogens.

According to Ohio State University Extension, much is unknown about the long-term effects of these worms, with research currently underway regarding control strategies in different environments.  Inorder to understand and track the presence of these worms OSU has developed a reporting site where Ohio gardeners can document locations of suspected populations. Gardeners should visit [ https://go.osu.edu/asianjumpingworms ] to report suspected locations and upload photographs.
​
Until effective research-based control strategies are developed to keep populations of this worm in check, gardeners should closely examine soil, compost, wood chips, and other soil amendments they move on or off their property. Learn how to identify these worms and educate your gardening friends and neighbors so they too can identify these worms.  If you do find these worms on your property, never share plants or soil with other gardeners.

It is hard to believe but our food waste and other organic materials such as paper and yard trimmings equate to nearly 55% of our total waste with food making up 20-30% of this total.  When these items are in our landfills they breakdown and create a material called leachate, which is toxic and can pollute groundwater, surface water and soil. Vermicomposting, a process that relies on earthworms and microorganisms to break down organic matter and transform it into a product that can be used as a valuable soil amendment and source of plant nutrients, can help homeowners with their gardening efforts but also keeps organic materials from causing problems in the landfill!
Vermicomposting is a way to get earthworms to work for you in a more organized way. You can become a worm farmer easily. North Carolina State University Extension is a leader in vermicomposting. Rhonda Sherman with North Carolina Extension, states that you need 4 items to begin worm farming.

1. Worm Bin – You can purchase this through many different garden centers and websites. You can even make this on your own. If you choose to make your own bin, make sure that it has a tight fitting lid and is a dark color. The bin size depends on the amount of food discards produced by your household. According to North Carolina State University, “The general rule of thumb is one square foot of surface area for each pound of food discards generated per week. So if your household creates two pounds of food scraps weekly, you will need a 2-foot by 1-foot worm bin that is 8 to 20 inches deep.” To access plans simply search on the internet for, DIY worm bin.
2. Bedding – Bedding is needed to provide a good living environment for the worms. Bedding should be a material that is nontoxic, holds moisture, and allows air circulation. Items to use could be, shredded paper, newspapers, paper bags, office paper, cardboard, decaying leaves, or coir (coconut fiber). Glossy paper or magazines should not be used.  The bedding should be soaked for 5 to 10 minutes in a bucket of water and then should be wrung out. The bedding should be damp but not soaking wet. Worms should have 6 to 8 inches of bedding or at least half the depth of the worm bin.
3. Worms – It is not as simple as digging worms from a yard or garden. Out of the 9,000 worms only 7 species are known for use in vermicomposting. Of those, the Red Wiggler (Eisenia fetida) are the type of worm that is used most often with home composting systems. You can buy red wigglers from worm growers found online but be sure to shop around because prices do vary widely.  Once you receive the worms, worms should be placed on top of the bedding in the bin. The worms will immediately start to tunnel under the bedding to avoid the light. If you notice worms outside the bin, place the bin in a well-lit area for a couple of days to help the worms get acclimated to the bin.   
4. Food Scraps – After a few days worms should be ready to have some food scraps added to the bin. Items like vegetables, fruits, crushed eggshells, coffee grounds, shredded paper, shredded garden debris are acceptable. Meat items including fish should never be added to the bin. Other items that should not be added are pet/human manure, fat, citrus, tobacco, or onions and garlic. Once scrapes are added, cover them with 1 to 2 inches of bedding to prevent fruit flies.
   
   

Harvesting compost overtime is why you vermicompost to begin! It is the valuable mixture of earthworm castings and decomposed bedding and food scrapes that will help your plants thrive. There are several methods that are documented by Rhonda Sherman, Extension Solid Waste Specialist with North Carolina Extension:

1. Sideways Separation - To do this you feed the earthworms on only 1 side of the bin to harvest the vermicompost from the other side.
2. Light Separation - Empty all contents of the worm bin onto something like a plastic shower curtain in the light. Wait 5 minutes and scrape off the top layer of vermicompost. Continue to do this until you find the worms in clusters. Replace the left-over contents back in the bin. Be sure to add fresh bedding (6-8 inches) to the bin.
3. Vertical Separation – By feeding the worms in the upper bin the worms will migrate to where the food is, leaving the compost in the bottom bin to harvest.
   
   

With all methods of harvesting you will need to incorporate fresh bedding (6-8 inches) into the mix to ensure that the worms have enough to continue to “work” through. Once your mixture is harvested it can be used immediately or it can be stored for later use. It is best to incorporate it lightly with the preexisting soil in the vegetable garden or around trees and shrubs. Vermicompost can also be used as a top dressing for your lawn.
Sometimes worm bins may have issues that arise over time. It is important to note that your bin should not:

• smell bad (could be that the bin is too wet, or not enough air is moving through, or too many food scrapes have been added),
• attract flies (could be too much food has been added, or food scrapes have not been buried enough),
• have mold (could be that conditions are too acidic),
• have dry bedding (could be too much air is moving through the bin)
• have large numbers of worms dying/crawling out of the bin (could be too much food or too little food has been added, or the bin has been exposed to extreme temps, or the bin is too wet or too dry), or
• have lots of liquid in the bottom. This is called leachate and should not form in the bottom of the bin (could be too much food has been added or that there is poor ventilation or overwatering). It is important to note that leachate is not compost tea and should not be added to your garden.

Vermicomposting is a way to get earthworms to work for you and convert your organic waste into a valuable soil amendment that you can use in your garden! Over time you will learn to understand feeding, worm care and how to best harvest your compost.
