Risk factorsBy Mayo Clinic staff
Although dangerous spider bites are rare, your risk of being bitten increases if you live in the same areas that the spiders do and you happen to disturb their habitat. Both black widow and brown recluse spiders prefer warm climates and dark, dry places.
Black widow habitat
Black widow spiders can be found throughout the U.S. but more so in the Southwestern states. They prefer to live in:
- Unused pots and gardening equipment
Brown recluse habitat
Brown recluse spiders are found most commonly in the southern Midwest and in limited areas of the South. Recluses are so named because they like to hide away in undisturbed areas. They mostly prefer to live indoors, in places such as:
- The clutter of basements or attics
- Behind bookshelves and dressers
- In rarely used cupboards
Outside, they seek out dark, quiet spots, such as under rocks or in tree stumps.
