After heavy rainfall, sightings of an invasive species have been on the rise in North Texas.
Hammerhead worms, named for their distinct hammer-shaped head, are a species of worm endemic to Southeast Asia, but they have become an invasive species in the United States. They can grow up to a foot long.
According to the Texas Invasive Species Institute, hammerhead worms are also toxic, and can cause skin irritation to humans and animals. They can also carry parasites.
The worm is a natural predator of earthworms, which are necessary for crop growth and development.
Hammerhead worms are able to reproduce asexually, and do so in a hydralike manner. Experts warn not to attempt to cut the worm in half if you see one, as the two pieces of the worm will then become two worms.
According to the TISI, a new head can begin developing within 10 days.
Experts advise killing the worm using a spray of citrus oil and white vinegar. The worms can also be killed by soaking them in salt or vinegar, or by freezing them in a sealed Ziploc bag for 24 to 48 hours.
It is also recommended to wear gloves while handling the worm and thoroughly wash your hands afterward due to the toxins the worm can transfer to humans.
