This "worm" is usually only seen during very high humidity situations, such as a lot of rain. They are usually found in cool, dark, moist areas. They eat earth worms, slugs, snails, insect larvae, and are even cannibalistic. They usually move and feed at night. They can survive desiccation only if water loss does not exceed 45 percent of their body weight. They have been found commonly in American greenhouses since 1901. Their mouth, which also serves as an anus, is present near mid-body on the ventral surface.

Colors of Florida species range from greenish-grey to brown with dark narrow stripes on the dorsal side. Sometimes they are yellow or blue in other areas of the country.

Also known as the Kew Greenhouse Flatworm.

This land planarian is slender and brown, with five dark longitudinal stripes; it can be large, up to 10 inches in length. The species is 'hammer-headed'. The head is shovel-shaped (wider than body) and there are numerous minute eyes along its border.

The species was discovered in 1878 in the greenhouses of Kew Gardens near London, hence its scientific name.

It has a wide distribution in warm climates. It needs a moist habitat and is usually encountered near outdoor water faucets, where the soil often remains wet. It original home is unknown but is possibly the Indo-Malayan region.

Flatworms are hermaphroditic. The eggs are encapsulated and affixed to objects in damp places. These are benign creatures -they do not damage plants or cause any medical problems.

There are four different species of these Bipalium flatworms currently found in the US. Three eat only earthworms; one eats snails and slugs. Bipalium kewense is found across the southern states and may get over 10 inches. It has five dark stripes along the back including a thin middle stripe. Bipalium adventitium is found across the northern states, reaching about 4 inches. It has one narrow dark stripe on the back. Bipalium vagum is the mollusk eater now found in the southeastern US. It has a three thick dark stripes, a dark neck collar, and two dark head spots.
A researcher (Pete Ducey) at the State University of NY (Biology Dept) is studying the spread and effects of these invasive flatworms. He welcomes questions and reports of sightings.

Found in an unfinished basement (damp, but dry concrete floor) in Raleigh, NC in July. The nearest entry point would have been a sump pump, and the worm was quite dry when found. Has a protuberance from the ventral surface--not sure what that is (see pic), but possibly the mouth?

Found them in several damp places across my gardens, and under pots. Found a cache of them near my compost bins where there are lots of earthworms. I think they came in from greenhouse plants. I've read that they eat earthworms, hence my negative rating. Plus they are just ugly for whatever that's worth.

These flatworms have devastated the earthworm populations in parts of the UK. Many farmers fields have been destroyed, because there are no earthworms left to aerate the soil. If you find them DO NOT CUT THEM UP! They will only regenerate and the smaller bits will turn into new ones. I'm trying to locate a way to eradicate them without harming the earthworms. No luck, so far.
UPDATE: Orange oil will kill them. You can buy online Orange Oil Concentrate manufactured by Medina Orange Oil. I know Amazon.com carries it. You can find more places to buy, by Google-ling 'orange oil concentrate'.

When I noticed its head was flat like a hammerhead I then knew it wasnt a snake. It was about 10 inches in length. I have lived in Eastern NC for 30 years now and have never seen anything remotely close. Kind of a strange creature.

We are in Coral Springs, FL 33071, about two miles from the Everglades boundary canal. Just found two of Bipalium vagum on the rim of my waterfalls and in the water of one of the cascade basins. The falls feed water to my fish pond which contains fancy goldfish and Apple Snails. Finding out that this obscene creatute is an invasive species is bad enough, without finding out that of the four types, this one prefers my Apple Snails. One of my prize fish has also taken an unidentified illness. What would happen if my fish cjhow down on these things? After all, the Bipalium vagum is equally at home under water as it is on the rocks and soil around the pond.

I have a question when I lived in Mississippi - Moss Point on the Gulf Coast... I went to my car one day and one of the worm snake things I see here .... basically attacked my leg
It snapped around my leg it was about 12 inches long and as soon as it attacked I swiped at it and screamed... it fell apart immediately... but left a mark on my leg.... it was slimy and had black strips down its back and has a twoheaded or one head curved similar to the pictures here... I was on my porch which is a cool area from the sun and back driveway... I didn't know what it was and no one believed me that I had been bite by it...but because I had a mark the doctor put me on antibotics... my question is can this thing be dangerous to a human...like reproduce in us or something... that would be a horrific thought... some creatures like it like a fluke and hookworm can do that... if so what should I tell my doc I haven't seen any worms come from me anywhere but... my central nervous system has been going wacko and no one can find out why...and I get massive headaches...and it just gets worse over time... any information would be great so I can relate it to a doc up here in the north where I live now... it has been a few years back that this occurred... I just hope I am ok and whatever is wrong with my CNS is something explainable eventually.

Land planarians eat earthworms. They should be destroyed. Do not cut them up as they will regenerate heads and multiply. Best to squish them or spray them with a mixture of orange oil (d'limonene) and water. 2 oz. of the orange oil to one gallon of water should be sufficient.

I found one of these worms in my house this morning. My dog was outside and must have brought it in on him, and he rubbed up against my comforter on my bed and there is where I found it. But the weirdest thing about it I automatically thought that my dogs had worms and I called the vet and took it to them to have them check it out for me. And in the long run it was a relief that there wasn't anything wrong with my dogs. But the thing that gets me is that I don't live around any water, or don't have a pond in my yard for these worms to be around. And it hasn't rained here for a few weeks. So why am I finding them around here now. I've lived here for 8 years and this is the 1st on I have ever seen!!!!
Are they harmful to animals or humans. I have kids and don't want anything to happen to them while they are playing in the back yard. Or anything to happen to the dogs as well.
Or anyone else that may come over to visit.
Any suggestions?????? I live in Pennsylvania and this was a very uncommon worm that I have ever seen. What may have caused it to come out now? Could there be more then just one in my yard that I have to be concerned about?
Anyone with info please let me know. I am very concerned about this type of worm.

It has been raining here profusely in the last week or so, and my husband came in the house this afternoon to report there was a small snake on the patio. Thanks to a recent Dirt Doctor (Howard Garrett) newsletter, I was able to identify this hammerhead worm. The newsletter warned that if the worm was cut in half, it would reconstruct itself unless put in full strength orange oil. I had some and did put both cut halves in the orange oil. However, in the next couple of hours, another larger worm of this type showed up on the patio. Since I'm not really crazy about hands on treatments with creatures, I decided to try a salt layer. Started with the head and as soon as the salt hit it, the worm gave a jerk, and I continued down the body, covering the body of the worm with the salt. Worked like a charm. I prefer the salt method myself; faster, cheaper, less messy, less personally involved.

Long Beach, California. Very interesting creature. My son and I found a larger one (two inches) and four or five smaller ones, balled together under a plant pot with slugs and sal bugs. We have seen them over the last few seasons. It is interesting how it lifts its "head" and sweeps around, similar to a snake. We teased the Wife, telling her it was a tapeworm, looking to her for lunch....

After researching online, we have decided to "off them", as we have an organic garden and have done our best to keep earthworms working hard. If there is a reason for NOT doing so, please let us know.

We started finding these worms about 7 years ago when we moved to this property which used to be a pecan grove. In the last three days, I have killed 13 of them by pouring salt on them. We have wonderful soil because of the earth worms and they are definitely eating them. I would say we have seen/killed over 50 of them in the last 7 years but they are starting to increase in population suddenly. I think it is due to the moist summer we have had but I am seeing many over 12 inches long now! They are just creepy and disgusting.

I live in Tennessee and I just found two of these hammerhead worms. They were living under an old foam seat cushion that I was saving for a template. One of the hammers was around 8 inches and the other around 3 inches. This has to be the most sticky creature I have ever found, it stuck to everything I touched it with like glue. I have never seen this creature before, and I am a very outdoor oriented person. There are loads of slugs where I live and maybe those are what is getting feasted on ( I hope so ), however there is also a large population of earthworms and night crawlers here too. I love my earthworms and night crawlers , but I hate the slugs found here they eat my plants and my cat food. Not sure what to do here I guess I could poison the slugs , kill the hammerheads, and save my good worms. Anyone have a better idea?

After 30 years of living and gardening in the same place, this year I've begun to find both kinds of land planarians in my garden - Bipalium kewense (long, brown with 2 stripes) and Bipalium adventitium (shorter, yellowish, one stripe). They hide under moist planters, pots, bricks. So I began using their hideouts as "traps", places I check to find them so I can then kill them. To kill them, I drop the planarians into a lidded plastic container (yogurt cup) that has 1/4" of diatomaceous earth in the bottom. I secure the lid. It works! I go out and hunt them after I irrigate, after rains, and in the morning. I check my "traps" and am regularly finding planarians. Physical / mechanical control is effective. By killing the adults, they cannot reproduce or increase populations. This way I'm protecting my earthworms.

It struck me, because it was a beige color, about 6 inches long, thin, with about 3 black streaks running the length of the worm. It had at one end what appeared to be a shovel-head or hammerhead. I live a 1/4 mile from the beach, but near federally protected forest land. I've positively identified it as a Hammerhead Worm (land planarian) (Bipalium kewense).

I've yet to find a live one, but I have cats and I don't really want them eating these worms. Is there any way to get rid of them? Or to repel them? Obviously something is killing them, but yet they keep coming in?! I'm sure it has to do with the extremely rainy summer we had in Georgia this year. But even with a dehumidifier running down there I still keep finding them. Any thoughts or suggestions?

I seen one on my walkway this morning for the first time. I have never seen one. I didn't know what it was until I started researching it. I didn't know if it was a worm or a snake! I read several things about it and didn't know it ate earthworms and was a harmful invasive creature. Now I wish I wouldn't have just let it go!

Lived in S Florida for 27 years, never encountered one of these until seeing one climbing on my door last night - juvenile, about 1.5" long. Funny thing is, there was a crushed snail shell on my patio the night before, no sign of the slug though. Could it be the adult worm ate it the night before?? I don't mind that they eat snails, the snails eat my plants, so I say thumbs up for these worms!

Found the first one I`ve ever seen, my wife said it was a blood sucker. Looked up hammer head worm on the net and it brought me here. I signed up and started reading all the bad things about the little guy I had just caught, especially the fact it ate earthworms. I went outside turned over a couple stones and found a 4" salamander, I pulled it out of the cup it was in, dropped it in front of the salamander; goodbye planarian bipalian or whatever it was. I live on 20 acres, mostly woods and have thousands of newts and salamanders, guess that`s why I`ve never seen one.

Found on doorstep rug at 2 am. Was about 10-12 inches long. I had never seen anything like it so I took a picture (posted #86) It scanned it's head back and forth over the ground as it moved forward.-Very much like a hammerhead shark hunting. Didn't know it was something bad so let it be. (Oops, -sorry earthworms) Should have fed it to the chickens, although it probably would have freaked them out also.

I saw one in my backyard and had no idea what I was. The main concern was that it could be harmful to my pets. Very interesting looking creature.
