TYLER, Texas (KLTV) – After recent rains here in East Texas, we’re seeing the re-emergence of an invasive worm. The “Hammerhead Worm” — named for the shape of their heads — is prevalent in our region. They typically measure up to 10 to 15 inches long; they have light-colored bodies that sport a dark stripe. They also pose a threat to your garden due to their diets.
These worms feed on slugs, snails and earthworms — which are critical soil aerators and decomposers. Losing them to predators can significantly reduce soil quality and alter plant growth. You should never touch these worms with your bare hands. They’re soft bodies secrete a toxin that can cause skin irritation, and can make your pets sick if they eat them.
They’re also incredibly tough to kill. Squishing them or cutting them in half can actually make the problem worse. That’s because of their ability to regenerate, which means each piece will become a new worm. Instead, you should put them in a sealed container filled with salt, alcohol, vinegar or citrus oil. You can freeze that container for 48 hours for good measure, but freezing alone won’t kill them.
If you see one of these worms, you’re encouraged to make a report. You can do that by emailing the Texas Invasive Species Institute at invasives@shsu.edu — you’ll need to provide a photo and location for the sighting. You can also make a report by reaching out to your local Texas A&M Agrilife Extension service office.
