Poisonous worm that regrows when cut in half

Heavy rains in Houston, Texas, are causing concerns about the emergence of poisonous hammerhead flatworms.

These worms secrete toxins that can cause skin irritation in humans upon contact.

They thrive in hot, tropical climates and can be poisonous to pets if ingested, often appearing on roads, sidewalks, and lawns after rains.

Experts advise against cutting the worms, as they regenerate into multiple worms when cut.

Residents should wear gloves, collect the worms in a plastic bag with salt and vinegar or citrus oil, and freeze them overnight to kill them.

Even after killing the worms, avoid direct contact; rinse any affected area with water, soap, and hand sanitizer if contact occurs.

Hammerhead worms, also called arrowhead or shovelhead worms, can grow up to 15 inches long and are often mistaken for snakes.

These worms prey on earthworms, paralyzing them with toxic slime before digesting them, and can reproduce asexually by breaking off a portion of their rear, which grows into a new worm.
