Anybody have any experience getting rid of these guys? I seem to have little grey squatters in my attic. I got a haveaheart trap and caught me an interloper, but I think he's part of a gang. I know where they're getting in (at least the main entrance) but I'm hesitant to plug it up until I'm sure they're out of the attic space. I don't want them trapped and either dying and stinking up the place or chewing through the ceiling to get out.
