To minimize clutter, it’s tempting to store off-season items in a hard-to-access place like the attic. Out of sight, out of mind, right?But because of their location (at the tippity top of a house) and because many are unfinished and uninsulated, attics are prone to high heat and humidity in warmer months and freezing temperatures during colder seasons. Those unregulated conditions make attics a lousy place to store a lot of the things you’re inclined stash away for most of the year.
