I live in NE Ohio and never do any of that except to winterize and put mice repellant like Fresh Cab all over inside. I did however put the stainless steel screens over my refer, heater, hot water heater panel openings, and bumper ends to keep bees ect out of those areas. The worst issues have been an occasional small wasp nest inside my A/C cover and Propane cover. Go for it if it makes you feel better though.
