Yep, it's that time of year, everybody will be firing up those water heaters, furnaces, and refridgerators. All the places those little squatters love to set up house keeping. There are a few of them who also like the range hood.
I've had mud daubers build their home in the fan motor of my range hood. When I turned it on, nothing but a humming sound and smell of hot wiring. All was well, after some cleaning.
