Watch Out For The Invasive Hammerhead Worm In Maryland

Did you know that there’s a toxic worm that may be hiding in your garden? This invasive species has actually been in Maryland for a while, but it’s recently gained more attention, and for good reason. If you attempt to cut the worm in half it can regenerate into TWO worms! This creature is remarkable in so many more ways and it may mean danger for your yard. Read on to learn more and be on the lookout…

Hammerhead worms are native to Southeast Asia. They were first spotted in the United States in the 1980s and have been spreading around the country ever since, including in Maryland.

The invasive worms can be identified by their unique “hammer” heads. They can grow up to 12 inches long!

Hammerhead worms mainly feast on earthworms. Since earthworms are known to help soil aeriation and add precious nutrients to the earth, a lack of them could mean trouble.

If you spot a hammerhead worm around your home and wish to get rid of it, DO NOT cut it in half. The back section that’s cut off is known to regenerate and become a new worm in a few day’s time.

That’s actually how they primarily reproduce as well. In a process called fragmentation, a small rear portion of the worm is pinched off and left behind. In about ten days, that portion forms a new head. This process can happen a few times a month, which means these pests multiply fast!

To eliminate a hammerhead worm, simply use ingredients you likely already have in your house. Salt or vinegar are known to kill them, and if you wish to discard the worm afterward, be sure to wear gloves. These creepy creatures possess a toxin that you’ll want to avoid.
