I woke up one morning and found tuis thing swimming in my toilet. This was BEFORE I used it! I have looked all over the Internet and can’t seem to find anything like it. It is rather flat, appears segmented and has a beak like protrusion on one end. It is literally swimming around in the water. I just moved into my place in February and am on a septic. Could it be something from that? Hopefully it didn’t come from inside my spouse!! We live on a coastal region of south eastern NC.

Fly Larva

Fly Larva

Dear Grossed out on North Carolina,
This is a Fly Larva, though we cannot say for certain which family.  Many Horse Flies have aquatic larvae, but this does not look like a Horse Fly Larva.  It looks most like a Soldier Fly Larva in the family Stratiomyidae.  See this image on BugGuide.  Your guess that it came up the drain from the septic tank is very possible.

    I also found this fly larva swimming in my toilet. I totally freaked, thinking I had worms, since I have had stomach problems, and was given medicine for bloating, which gave me diarrhea (but nothing was in the stool).
    This bug was just swimming in the toilet when I went to us the toilet. My question is, can it get inside humans?

    Why do these only show up when it rains alot?
    Are they coming from the septic tank?

      I found one of these in my toilet after I went pee. I’ve been sick and not sure if it came from inside me or the toilet but I
      Haven’t seen any more in the toilet since. I’m taking my “wormy” to an Infectious Disease Doctor tomorrow, they wanted me to freeze it. I’ll let you know what I find out!

      Did that come from me or the toilet?

  4. I am in a panic, there were 2 of these in my toilet this morning. Any updates from previous posters? Help! I just want to know they are not living inside me!

    Hi I found one in my bed last night!! How could it have gotten there? I’m worried there are more hiding

    I nearly fainted when I saw them in my toilet last year. Thank God I haven’t seen any more of them, I came to the conclusion they came from the toilet and not me. However, I don’t know what to think after reading this article:https://www.dailymail.co.uk/health/article-3662079/Woman-peed-WORMS-3-months-infestation-fly-larvae-bladder.html
    This is mortifying!

    I have found them in my toilet several times after the dog has had diarrhea and I have flushed it down the toilet. I believe he must eat the eggs and they hatch inside him. Took one of them to the vet and they had never seen one.
