After a month of terror -- squirrels (and some rats) wanting to claw their way through my attic into our kitchen and dining room -- they're gone!!! You see, it's exceptionally cold here this year so they were just looking for a warm place to sleep.
A local (professional) "Critter" guy spent two weeks trapping all the attic creatures (and yes, all the captured critters were released into the wild). At the same time, he completey critter proofed our roof from future invasions.
Now there are no more rodents playng and chewing on my roof and attic keeping me (and my ferrets) up all night wondering if this is night they'll make it in.
