Worms Found on Deck Could be Horsehair Worms, or Just Dry Grass

“Can you tell me what this is?” asks this reader in her submission regarding the long, white objects pictured below. “I found it on the steps to my deck in Mansfield, Ohio. They look like long blonde hair but some of it moves like a worm. Thank you for your time!” Now, if we were to assume that these are organisms, and look only at the photograph our reader sent in, we would suggest these could be horsehair worms, as they can look like this – like long strands of “blonde hair”.

That said, having seen the video our reader sent in, we are going to have to disagree with her on one point – they do not move like worms at all. In fact, the only part of these worms that moves in the video is one bent ‘piece’ that is sticking up in the air and which seems to be ‘swaying’ in the wind, which is all we think it is doing. And for that reason, we are more inclined to think these might just be pieces of dry grass, rather than worms. They likely just blew onto our reader’s yard from somewhere: maybe a neighbor recently cut their grass. Additionally, if these were horsehair worms, then all of the ‘worms’ would be moving, and they would be writhing around each other in a far messier tangle – they are not nicknamed ‘Gordian worms’ for no reason. This name comes from the myth of the legendary Gordian knot that Alexander the Great cut with his sword.

With all of this said, if our reader is absolutely convinced these are worms, then we suggest she get a second opinion. She can put a few of the worms in a box with air holes and take them to her local county extension office. There someone will be able to physically examine the worms and may have a better chance at identifying them. Additionally, if any of our other readers have any insight about this that they want to share, they are more than welcome to do so in the comments section below.

Video of Grass Swaying in the Wind

To conclude, we do not think these strands of “blonde hair” are worms at all, but probably just pieces of grass. We can understand that these do slightly resemble worms, and we bet they gave our reader quite the scare, but we do not think she has anything to worry about. Even if they were horsehair worms, these worms, while being parasites of insects, do not take humans as hosts. We hope the information we provided proves helpful, and we wish our reader the very best!

  1. This worm is not swaying in the wind ! If u watch closely it goes all the way down several times and touches the wood and comes back up. If the wind was causing it to move the other ones would be moving as well. I have delt with this parasite for almost two years now! My understanding is it’s horse hair worm and yes it can enter the human body bc I along with 8 other people I kno have been dreadfully dealing with this horrible parasite that has taken over my life! I’m so tired of seeing post that say it has not been studied much but it’s harmless to humans! This is not true! It does affect humans and if it hasn’t been studied much how do they kno! I have lived with this Torturing my body for going on 2 years, and something needs to be done bc hundreds of people have this and nothing is being done about it! I see it in clothes and clothing stores, I see it almost everywhere I go and people pass it off as just lent at smaller stages! This is not lent it is going to end up being a pandemic if something isn’t done about it! It is in our clothing stores everywhere! Where is this coming from and why and how do u get rid of it ? It’s very serious and the Drs tell everyone they are nuts bc they don’t kno what it is! Something has got to be done about this!!!
