The thing is they're not in the attic(that I know of). They seem to be in the left hand side of the house which is only one floor. I can hear them between the roof and the ceiling and I even saw one of them chilling on the roof by the gutter.
We are gonna have to set traps around the top of the house where they're coming in and out from. I heard they have to come outside at least every 24hrs.
The thought of them chewing their way into my living room makes me sick.
