It's 1:00am, and I kept hearing a hissing, almost like buzzing sound coming from behind a tub I have. I won't lie, my room is a a bit of a clutter (as I don't have a dresser as of yet), but it's not a disaster. Anyone know what could be making these strange sounds? I've heard it in the common area before, it's ceased but I heard it outside my room too. I feel like I'm going crazy. Should also mention that I live in the basement, but it's all been redone with hard wood floors. We've had centipedes and spiders but we had an exterminator come in, in later October.
