Worms Swarming Home After Heavy Rains are Blackworms

“Thin black worms, the size of red wigglers, are coming in from outside under the door,” writes this reader about the critter pictured below. “It’s been raining heavily during the night in Hendersonville, North Carolina. I do not see any legs. I live in a long term care facility and don’t want to see them harmed. Thanks for your help.” Firstly, we want to thank our reader for the very helpful context, which in this case is especially helpful since the photo is pretty blurry. Knowing that it does not have legs rules out a lot of possible identifications and helps narrow down the possibilities. Secondly, we commend our reader for not wanting to see the worms harmed. We know, and understand, that a lot of people’s first instinct when they find worm-like critters in their home is to kill them, even if they are harmless.
