#MDACF - What #Mainers are Asking About #JumpingWorms

February 25, 2026

'Following a recent two-day jumping worm workshop hosted by the Maine Department of Agriculture, Conservation and Forestry (DACF), it is clear that jumping worms are a top concern for #Maine #gardeners and land managers. This event brought together a knowledgeable lineup of leading researchers from across North America to share the latest science and management strategies.

While the first established populations in the state were discovered as recently as 2014, these invasive pests are now considered widespread and have been confirmed in 13 of Maine's 16 counties. With hundreds of questions submitted by workshop registrants, several key themes emerged regarding how to identify, manage, and prevent the spread of these invasive worms.

Identification: "Is this a jumping worm?"

Many Mainers are concerned about distinguishing jumping worms from other species of earthworms.

- Monitor with a Mustard Drench: To see if jumping worms are present at your location, mix 1/3 cup of ground mustard with a gallon of water and pour it directly on the soil (in a forested setting, brush away leaf litter first); this irritates the worms and brings them to the surface for identification.
- The Timing: Because they are annuals (having a lifespan of only one year), juveniles appear in May and June and are very small and hard to identify. It is best to wait until late July or August to confirm their identity once they develop their distinctive collar.
- The Look: Look for a milky white or gray collar (clitellum) that is smooth, flat, and completely encircles the body like a ring. In contrast, European earthworms have a raised, saddle-shaped clitellum that only goes partway around.
- The Behavior: Jumping worms do not crawl like typical earthworms; they thrash vigorously and wriggle like snakes when touched.

Spread & Prevention: "How do I stop them?"

The most common way jumping worms move is through human activity, particularly the movement of soil, compost, mulch, and nursery plants.

- The "Hidden" Threat: The worms themselves die each winter, but they leave behind tiny, soil-colored cocoons that are nearly impossible to see.
- Arrive Clean, Leave Clean: Cocoons can hitchhike in the treads of #HikingBoots and #tires. Using boot brushes at trailheads and cleaning tools before moving between garden beds is essential.
- Plant Sales & Nursery Stock: When possible, choose bare-root plants and rinse the roots into a bucket to ensure no cocoons are hiding in the root ball.
- Contain and Return: Always dump the wash water and mud back onto the original site where you collected the plants or soil; this ensures you aren't accidentally moving "hitchhiking" cocoons to a new, uninfested area. If you need to dispose of the material, wash your gear over a bucket to capture the sediment, let the soil settle before pouring off the water, and once the remaining mud dries, bag and #solarize it (heating it to at least 104F) before putting it in the trash.

Things you can do right now:

- #Solarization: In Maine, this works best in the peak of summer when the sun is strongest. Spread a thin layer of infested soil, about 6-8 inches deep, onto a #DarkTarp and cover it with a clear drop cloth, sealing the edges to create a "package." Place a simple soil thermometer in the center to track temperature. Research suggests reaching 104F for at least two hours can kill the worms and egg-containing cocoons. If you don't have a soil thermometer, plan to leave the covered soil in full sun for at least three days. On clear, hot summer days, a thin layer will often reach target temperatures within one to two days, but the extra time helps ensure consistent heating throughout the pile and improves your chances of success.
- Hand Removal: For small populations, you can hand-pick worms and drop them into a bucket of soapy water to kill them."

#Maine [and #NewEngland] - Help Track a #Hemlock Pest

February 26, 2026

"#HemlockWoollyAdelgid (#HWA) is an #aphid-like invasive insect that feeds on and can kill hemlock trees in Maine. To find HWA, look:

- On hemlock trees. In North America, HWA is found only on hemlock trees.
- On the undersides of hemlock twigs. At this time of year, HWA is covered in white tufts of wax and is easy to see. Look for discrete 'woolly' masses.
At fallen twigs on top of the snow, as this will give you a picture of what is happening high in the crown. Unless you are in an area where HWA is commonly found (such as southern coastal towns), please let us know if you find it.

Unless you are in an area where HWA is commonly found (such as southern coastal towns), please let us know if you find it. "

Wikipedia: "Accidentally introduced to North America from Japan, HWA was first found in the eastern United States near Richmond, #Virginia, in 1951. The pest is now found from northern #Georgia to coastal# Maine and southwestern Nova Scotia as well as areas of western #Michigan near the eastern #LakeMichigan shoreline. As of 2015, HWA has affected 90% of the geographic range of #EasternHemlock in North America."

It's that time of the year! And now I've been transporting #AsianLadyBeetles from the upstairs (where kitty spends a lot of her time), to the downstairs where I grow plants because ALB's eat #Aphids! Now, of course, they could crowd out #Ladybugs if they get out of control, so I won't be saving every single one of them. But still...

Multicolored Asian lady beetles

Quick facts

- The multicolored Asian lady beetle has become a nuisance in Minnesota.
- They cluster around buildings in large numbers during fall in search of protected sites for the winter
- Control measures should only be used to prevent entry of Asian lady beetles indoors.
- Multicolored Asian lady beetle and other lady beetle species feed on aphids and other soft-bodied insects that can damage plants in agricultural crops, gardens and landscapes.
- These are beneficial insects to farmers and gardeners.

Asian lady beetle as a household pest

Multicolored Asian lady beetles can be a nuisance when they occur in large numbers inside homes.

- They do not infest wood, destroy fabrics, eat food or damage other property.
- These lady beetles cannot sting and do not carry disease.

Some concerns with multicolored Asian lady beetles are:

- Some can bite hard enough to break human skin, causing minor, short-lived discomfort. These bites happen when the beetles are searching for moisture or food.
- They can secrete a strong-smelling yellowish liquid from the joints of their legs. This liquid can stain light-colored surfaces.
- Exposure to dead lady beetles in buildings can cause allergic reactions in some people"

[Not mentioned: They can be toxic to cats and dogs if ingested!]

List of #Woodpeckers in #Maine (With Pictures)

"While the populations of many species have declined, that of woodpeckers has increased steadily in the state. In November 2022, their numbers almost doubled from the previous year. The smallest and most common woodpecker calling the state home is the downy woodpecker, measuring 6.1 inches. On the other hand, the largest is the pileated woodpecker, measuring a whopping 17.5 inches!"
