Winter storage advice- interior of trailer?

Foremost, make sure every little speck of food is gone. I always take the fall clean out opportunity to lift the vinyl shelf liner and wash the shelves...amazing how many bits of this and that are on the shelf. Wash the inside of the frig and be sure to prop and door open. I also vacuum all of the upholstery and wet mop or Swiffer the floor. We use Damp Rid for moisture....available most everywhere. We set them in the sinks just on the outside chance that one would overflow...never has happened, but we still do it. Also have used dryer sheets and never had a critter....not to say this is the reason, but at least the trailer smelled nice when we opened up. Actually, as mention on the TT side, I'm going to ask our pest control guy to spray the trailer when he does the house in November. Since we store at home and undercover, we can easily be in and out through the winter to keep an eye on things.
