Currently, there is no effective eradication method for the Asian Jumping Worm (also known as the “crazy worm” or “snake worm”) found in Denver’s Hilltop neighborhood, according to a statement from the City of Denver. For more information, visit the Colorado Department of Agriculture (CDA).
The CDA is urging nurseries, landscape contractors, and landowners to keep an eye out for signs of this invasive pest. Please report any suspected sightings.
“Preventing the spread of the jumping worm in Colorado is critical for safeguarding the state’s healthy soils and native plants,” stated CDA Plant Director Wondirad Gebru.
“With no effective eradication methods available, we appeal to gardeners and landscapers to remain vigilant, inspect materials, and report any potential sightings to authorities.”
This insect, native to East Asia, was first discovered in a California nursery in Napa County in 2021, and later in the wild in Sonoma County in 2023, according to the state Department of Food and Agriculture.
“As their name indicates, these insects wriggle violently and can even jump,” stated the California Department of Food and Agriculture in December.
“Jumping worms are far more voracious and grow faster than most native earthworm species. They typically inhabit the soil surface, quickly depleting leaf litter and diminishing beneficial microorganisms within the soil.”
According to the Colorado Department of Agriculture, the Asian Jumping Worm is distinguishable by its red and brown coloration and exhibits a snake-like jumping motion when disturbed. Unlike native US earthworms, jumping worms possess a clitellum that is white to light gray and encircles the body.
The CDA advises that a telltale sign of jumping worms in your garden is a soil surface resembling coffee grounds, which are actually worm droppings.
