Hello,
Posted a while back regarding a nocturnal pest
that keeps scratching/knocking either our attic or
chimney up in the roof at night.

We had a mice inspector come to the attic and
found no traces of mice. Thus, we have been unable
to identify the pest that is bothering us.

Is there some device or material we can buy and
place on our attic to keep nocturnal pests away?

I'm told that a radio tuned to talk stations and turned up pretty loud is
disturbing to at least Racoons, if not other larger pests.

Throw one up there and crank it up. Might have to sleep with earplugs for a
few nights and/or explain to the neighbors what's going on, but it might
just drive whatever's bugging you away.

You could also rent a live animal trap, bait it and see if you catch
anything.
