Did you hear that noise?

So, we got in to our house, finally got our stuff from the movers, and we're currently in the process of getting everything unpacked. Monday and yesterday were the first nights we spent in the house and we started to hear something scratching and rustling. At first we thought it was someone or something out in the back yard. But I checked and there was no one there, and I heard it in the wall and I said to myself "Oh crap."

Now, we're waiting on pest control to get out to the house and trap it and then remove it. Yay for texas.
