Where and how long can I keep a whole fresh winter squash?

If refrigerator space is in short supply in your house, you’ll be happy to know that a whole winter squash can be stored in a crawl space or the basement (if it’s not damp). For how long? Opinions vary, but some say that, if conditions are right, a winter squash could last as long as 6 months! These products earned the name winter squash because, prior to the invention of refrigerators, they were kept in cool “root cellars” and lasted all winter. They last a long time because the hard skin prevents water loss. They store well in a cool, relatively dry place that’s about 55°F and allows some air circulation.  Your squash should be stored just up off the floor so air can circulate around it. No other vegetable should be touching it. 
If you don't have a place in your home that's about 55 degrees, store the squash in the refrigerator. 
 Do not wrap a whole raw squash. It needs air, and its hard shell will keep the flesh from drying out.
