Smooth Bright Red Larvae Could be Bloodworms

We just heard from a reader in distress who has some unwanted visitors in her bedroom. She said she has been finding bright red worms or larvae for the past two years on and off, and the recent discovery of one of these organisms on her bed put her over the edge. She described them as legless, hairless, 5 mm long, 1 mm wide, with a dark spot at one end.

She didn’t send in a photo of the worms, but she emphasized their bright red color so strongly that we think we know what she is dealing with! We believe that she has been finding midge fly larvae.

Midge fly larvae are sometimes referred to as bloodworms because of their vibrant blood-red color. They live in aquatic and semiaquatic environments, so when people discover them inside their homes it is often in the bathroom. We do not know why midge fly larvae keep appearing in our reader’s home, but it could be due to moisture levels. She mentioned that they have been showing up periodically for two years, so perhaps when there are large storms or changes in weather patterns they appear. Also, this is all assuming that she has in fact discovered bloodworms, which we can’t be certain of without a photo.

Fortunately, although they are unsightly, bloodworms are harmless to humans. Like most larvae, midge fly larvae eat organic matter. To say farewell to these visiting larvae, our reader will need to eradicate any potential food sources in her bedroom. Perhaps her bedroom is attached to a bathroom and that’s where the worms are coming from. We suggest she do some deep cleaning to see if that keeps the critters at bay.

Finally, if she doesn’t believe these are bloodworms, we ask her to send us a photo that we can investigate.
