Hammerhead Worm Invasion in Houston

As Houston braces for Hurricane Beryl, another threat looms: the rise of the poisonous hammerhead worm. With the region expected to experience damp and humid weather, the invasive hammerhead worm species is set to thrive. These worms can grow up to 15 inches in length and have a hammer-shaped head. They secrete toxins that can cause skin irritation and can be fatal to pets if ingested. They are also bad news for the environment as they prey on earthworms, paralyzing them with their slime.

Dealing with the Hammerhead Worm Threat

"It will regenerate. So if you chop it into two pieces, you get two worms," warns Ashley Morgan-Olvera of the Texas Invasive Species Institute.

Chopping up these worms is not a solution, as they can fully regenerate. The recommended method of disposal involves placing them in a plastic bag with salt and vinegar or citrus oil, and then freezing them overnight. Always handle with gloves, even when dead. If you come into contact with one, wash the area with soap and water and apply hand sanitizer. If a pet consumes a hammerhead worm, seek veterinary assistance immediately.

Hammerhead Worm Presence in the US

Native to Asia, hammerhead worms have likely entered the US via plant trade routes. They are predominantly invasive in the southeastern states, with confirmed populations in Texas, Alabama, California, Florida, Georgia, Louisiana, Mississippi, and North Carolina, and South Carolina. With the potential for further spread, it's important for residents in these areas to be vigilant and take the necessary precautions.
