I got woken up last night to the sound of something chewing away at something in my attic. I get the ladder out and go into the attic at O dark thirty (2:00am). I don't see any critters but found lots of rodent crap.
Little bastards! I have baited two traps with peanut butter and set them right in the path of their blazed trail in the insulation. 24 years in this house and I have never had rodents in my attic.
Will update later with results.
