The giant house spider's original habitat consists mostly of caves, or dry forests where it is found under rocks, but it is a common spider in people's homes. E. atrica is one of the biggest spiders of Central Europe. Females grow up to 18 mm, males up to 15 mm. Adult males can be found from July to October, adult females occur all year.
