Native to the desert regions of the southwestern United States, this spider is well-adapted to hot, dry conditions. As a result, many assume that this tarantula species requires a heated enclosure to thrive. However, this is not the case. While temperatures in the wild can often exceed 100°F, Arizona blonde tarantulas are just as happy at room temperatures like 65°-80°F. This spider can even tolerate brief periods of cooler weather without ill effects.
