We moved into our new home 3 weeks ago and have started hearing noises at night, seem to be from the attic. At first I didn't think much of it, figured it was just creaks from the house or the wind. Now we hear them every night and they get louder. I listened closely last night and it sounded to me like something big scurrying about, like a squirrel. That seems plausible since I see squirrels in our backyard everyday, and one of the bedroom ceiling lights suddenly quit working the other night, so maybe one of the buggers chewed the wires. If that's the case, need to take care of this ASAP before we have a fire hazard from these critters. I haven't been up there since we had the house inspected as I've been busy with so many other things, and even then it was only to take a peak through the access panels, so I'm going to go up there and do a thorough inspection and look for signs of rodents and damage. I guess my next step would be to have an exterminator come out and trap them, and figure out how they're getting in and seal it up, maybe a gap somewhere in the roof and siding? The scurrying noises are one thing, but I could swear that sometimes the creaks are so loud and go across the ceiling like somebody was walking around up there, sure seems like it take more weight than a small rodent to make noise like that. I have gotten out a bed a couple of times in the middle of the night and walked around checking all the rooms to make sure there no one was there.
