A reader wrote to us a few days ago about some small black worms she found at the bottom of her kids’ laundry basket. She also found a couple more worms when transferring their clothes from the washing machine to the drier, so the worms can evidently be traced back to the clothing of her children. The reader was wondering what these black worms in the laundry basket are, and we think they might be leeches (which are actually worms) or potentially slugs (which aren’t worms).
