Some spiders hibernate during the winter months, but that's not true of all spiders. Spiders that do hibernate usually hide under the bark on a tree or under piles of leaves.
Brown recluse spiders are known as warmth-hunting spiders, because they seek out shelter in the winter and remain active. This type of spider generally likes to hide in homes and other structures, in dark places that are rarely disturbed.
