A reader wrote to us recently to ask about two worms she found in her kitchen. The worms have red bodies and tan heads, and they are perhaps a half an inch (one centimeter) long. The reader isn’t particularly concerned with what they are, and is instead focused on the question of where they came from. She has no indoor houseplants, and her windows and doors have been closed. She also says she has no food, but it is hard to take this literally, so perhaps she just doesn’t have food that is laying around the kitchen. As the reader points out, though, these two worms must of come from somewhere, and where might that be?
