Put the chairs inside or in the basement. Definitely bring the cushions in as that will certainly help with. Or shrink/heat wrap them like they would a boat.

Oh, those are nice chairs. You have my deepest sympathy. I've had mice chew through plastic tarps--just crazy! I store the cushions inside the house. I have put mouse poison around the attic when I store things up there with good results.

Sadly, I don't have room for these chairs inside during the winter (hence... the covers). I could definitely put the cushions in the attic, where we have mouse traps already. But would that save the chairs (left outside) from the same fate? My pest company has "bait stations" on the outside of our house, but just having an additional bait station next to the chairs wouldn't help... or would it? Perhaps worth a call to the exterminator.

Bring the cushions inside... flip the chairs over so there isn't a nesting site available. Make sure you clean your chairs of debris before you store/cover them.

Hmmm.... if I flip the chairs, am I now negating the need for those beautiful furniture covers I paid so much for (but only come to the base of the legs? :) Interesting idea. Maybe the furniture covers are still useful to some extent, since the chairs would basically be diagonally balanced if we flipped them over. Anybody done this?

I would get a couple large Christmas tree bags and zip the chairs up in them so they are encased. No entrance unless the little suckers chew through the bags!

Good idea about the Christmas tree bags, but these chairs are way too wide for the bags I've seen. In addition, I would be concerned about mold if I had the chairs entirely encased. (That's why the furniture covers normally have venting of some kind... the covers get wet and the water will soak through, but with venting at least the water vapor can get out.) Sigh.

I live in the south (humidity) and have used the Christmas tree bags with no issue with mold.

You might be right, Patricia... you don't think the "webbing" (for lack of a better word) would have the same problem? I can play devil's advocate on my own question, since the ottoman did NOT sustain damage. Just asking if you have experience with this kind of thing.

"you don't think the "webbing" (for lack of a better word) would have the same problem? "

Potentially but much less likely.
