How do spiders survive in dark isolated areas?

Everyone is familiar with basement spiders or abandoned building cobwebs. My question is: How do these arachnids survive (and seemingly thrive) indoors in the dark away from any abundant food source (bugs)?

Most likely there are bugs there, you just don't see them. A lot of them are tiny mites or small insects that found their way there. If not, many of those spiders can survive several months if not over a year with no food. So even if they rarely get a meal, they can still survive there fairly easily.
