Small Bug with 2 long arms like lobster pinchers
Sat, Mar 21, 2009 at 5:07 AM
I found this bug twice in our bathroom and this morning in our kitchen. I was reading the paper and it might have crawled off my t shirt. Unable to identify it.
Flushing, MI



Dear Doug,
This is a harmless Pseudoscorpion, a minute predator often found indoors. We get countless identification requests from around the world on Pseudoscorpions, and we should probably include it in the Top Ten Tag. Though your photo is not the most detailed we have ever received, we love the inclusion of the ruler in the photo so our readership can see just how tiny this amazing predators really are.

    Thank you so much guys. I found that bug (know identified as Pseudoscorpions) in my bathroom and I was worried if it was some type of wood tick/flea or possibly bed bug and I was searching the web and your website was the first to appear and the first to show me what this is. From Canada and -30 C weather here in winter right now, I was wondering how this guy was not dead.
    THANK YOU so much for getting a fear out of my mind.

      Hi Christy,
      We are so happy to hear we were helpful for you. Pseudoscorpion images taken indoors are quite plentiful in our archives, but specimens in nature are noticeably absent. This leads us to conclude that it is beneficial for Pseudoscorpions to cohabitate with humans. The -30C temperatures are a good reason for Pseudoscorpions to seek shelter indoors.

  5. Ned says:

    Life is full of wonderful little things and wonders. I found one of these brave little creatures in my Vermont kitchen and when I poked it with a pen looking through a magnify glass the claws raised with shear determination. And we think we have it so tough!?! Life is Good!

    I just found one of these in my bedroom crawling on the wall. I live in northwestern PA and I was hiking earlier today–maybe brought him in from the state park?

    • Samantha says:

      How do u get rid of them?

      • Jocelyn says:

        No need to, they’re beneficial and eat the bugs we don’t want. They can’t hurt you. I’d imagine to get rid of them you’d have to remove their food source, hence all the other bugs in your house. Kill all the bugs, and prevent them from reentering the house, and that should keep them out as well.

    Found one in my bathroom just now! Would have been freaked by it if I hadn’t already known about them from doing a bit of research on scorpions earlier this summer. I put it in a container to show my family when they get home later. It’s a cute little chubby one, and I’m kind of tempted to keep it to add to my scorpion “collection” lol. They’re really fascinating creatures. I may put it back though, to keep the earwigs and other crawlies that like to overrun my bathroom from getting too out of hand again. I also have several spiders that live in the corners, I let them stay. Only place I remove the spiders from generally is the bedroom, they like to bite me when I’m sleeping. Kind of amazing to think we have our own little ecosystems in our houses that we never even notice!

  9. Janice says:

    THANK YOU! I have looked all morning on the internet to try and find out what this guy is. He kinda looks like a crab so my search was useless. Scorpion? Who would have guessed. Glad he is harmless so it can stay . This is the first live one I seen. We have them stuck to the panel tape in our bedroom . Amazing little critter.

  14. Jonathan Blake says:

    The one in my bathroom in Vermont has much longer arms and much larger pinchers that truly look like a lobsters big pinchers. So far I have not seen a picture of the one I’m seeing.

  15. Amy Garcia says:

    I found one in our shower this morning in New Mexico. It was really tiny! It’s really interesting to find things that I have never seen before.

    • Mary Cope says:

      I live in Lovington, NM and I found one on my bathroom sink and another one crawling up my son’s shirt sleeve today. I’m so glad that these little guys are harmless. Now I don’t have to be worried if I see one in my house again.

  17. Jessica says:

    NW. Arizona,,, noticed a large house fly in the window,, that was struggling, then noticed one of these insects,holding on to the flies wing with one pincher, and to the flies body with the other claw,. The fly was at least 10 times it’s size, and it had the upper hand on the fly, until I killed them both,,,,,,
    Now that I know that its harmless to humans,,,, I’ll feel sorry for it the next time I kill one. Thanks for the info. Mark

  21. Meg says:

    Found one in the kitchen on the counter. Thought at first it was a tick but the pinchers didn’t make sense. Tried looking it up as crab like and nothing came up. Showed picture of it to co-worker and they figured it out. Feel bad killing it now. Now that I know they are good I will leave them be. Live in Torrington CT.

    The pseudo scorpion DOES BITE! I had one in the band of my sock and upon me moving the sock I WAS bitten ( felt like a sting)

    • Shadell Mullen says:

      I was bit too! All over my back while sleeping it make me feel sick I found him smashed after inspecting I know that’s what was biting/ stinging me!

  23. Marie Zanol says:

    Mankato, MN
    Found one crawling on my bedroom ceiling. This was the first website with any commonality in the bug my fiancé squished. The pinchers are fierce!

  24. Barb Unit says:

    Found one in the Northwest Territories in Canada ??

  25. Debra Vaszuez says:

    NW Ohio checking in, found crawling on the wall near the bathroom sink. Glad to know they don’t bite humans, but now wonder where his prey is! Will be releasing him outside, after I show the family.

  26. Phyllis Hart says:

    Thank you for this web site. I found one in the bathroom last evening. First one I’ve ever seen. My first thought was that it was a crab louse (!) With a magnifying glass I had a better look at it. A miniature crab indeed. I freaked a little, began to itch and took a soapy shower. I have him (?) captive in a tiny ziplock bag. I won’t worry so much now. Interesting to see where all these creatures live.

    • bugman says:

      You should release the little predator outdoors, though almost every Pseudoscorpion on our site was found indoors. They have adapted well to cohabitating with people.

  27. Gayda Dahl says:

    I wish I had not been so eager to kill this little harmless to us but not to other peskier bugs! It looked so lethal I feeaked

  28. Gayda Dahl says:

    I live in Georgia and it has been very hot and humid this summer so I’ve seen an over abundance of bugs. I found this tiny red scorpion like bug crawling up the side of my bed. I freaked out and killed it but after looking it up and finding out on your website that it is harmless to humans but lethal to other bugs I wish I had just relocated it to my floor corner…

  29. Chris says:

    Found several in my bathtub this morning I hit the ceiling thinking I had crabs!!!! So glad this page is here to help inform people because I was going to beat the life out of my husband.

  30. G.Green says:

    Ok Bugman, Please clarify for me if the pseudo scorpion is capable of either biting or stinging a human and can you do so definitively? I am referring to the following specific post from this thread:

    • bugman says:

      Pseudoscorpions lack a stinger, so they cannot sting. Pseudoscorpions are predators and they have a mouth to eat small creatures, so they can bite. The bite, if it occurs, would not be dangerous to a person.

  31. Reg says:

    Oh my god found 2 now in the bathroom. Extremely itchy right now. If they get on your clothes will they fall of?

  32. Candak says:

    Found one in my bathtub just today! New town Nd where the weather is barely warming up each day and the ice is melting in our lakes. The whole 42 years of my life we’ve never encountered this bug species! Neat!

  33. Joshua says:

    Found one in on my shirt this evening in Nova Scotia. Thanks for all the info. everyone. Quite a brave little guy. Got very defensive and raised his pincers when I removed him. If he freaked me out, I can only imagine what I looked like to him! 🙂

  34. Jae says:

    Amazing.I live 30 miles east of Cincinnati Ohio on the edge of Appalachia. I have a nightstand by my bed and am setting here watching youtube videos. Here comes this tiny I mean tiny spider looking thing with one long claw and one short. No bigger than a flea. Yes that’s a good size comparison. I grabbed my magnifying glass and was amazed at the vicious looking I dont know what. Thinking wow I wonder how many of these has been all over me when sleeping. Ugh. It was cartoonish how the tiny body with one huge claw slash pincher being held way up in the air while smaller claw kinda dragging behind. Anyway life is an adventure and I love it.

  35. Mary Ann says:

    Found at least 2 in MO, USA, while emptying a box of old mail and misc. papers. Now I’m being careful not to squish any of them, and finding safe places to put them, as I do, like the corner of the bathroom or under a cabinet at the baseboards, LOL! There was apparently a breeding ground for them in this big old box!
