“I live in Calgary, Alberta, Canada and today found these larvae or worms on a towel on the floor by my bed”, writes John from Calgary, Alberta, Canada about the striped, worm-like creature pictured below. “My two dogs also sleep in the bed. Please help!” Based on the photo alone, we can tell that this is a carpet beetle larva. This is because we have written about these critters more than any other worm-like organism on this site. If one were to judge what the most commonly-spotted critters in one’s home were, they would think that carpet beetle larvae are right up there with spiders and house flies. But that is not really true: despite being common, not everyone is as likely to find these in one’s home.
