In nature, black widows build their webs on rocky outcroppings, under logs, and between stones, rock crevices and under loose bark and stones, in small trees and under bushes. Amidst human habitation, they typically hide in sheltered, dimly lit locations such as garages, dark corners, basements, closets, and cluttered areas.
Diet
