We received a question from a reader who found some skinny, dried-out worms, or what might be worms, in her house. The reader is especially perplexed about her present case because she is finding the worms (or whatever they are) on the second floor of her house. She offers several possible explanations, and asked us to weigh in on the matter, which basically amounts to asking us if we know how worms get into houses in general.
