About
The giant house spider is the larger cousin of the house spider (Tegenaria domestica), and can be found living behind the fireplace, under the sofa, or in the bath. They tend to keep themselves to themselves, preferring dark corners where they can live in peace. But in late summer and early autumn some spiders become more active as males reach maturity and seek out a female to woo. The males stay with their chosen females for some weeks, mating numerous times until eventually they die, at which point they are eaten by their female. Giant house spiders spin sheet-like cobwebs in neglected corners of the room and wait close by for unsuspecting insects to get caught. They are most active at night.How to identify
The giant house spider is one of several very similar species of house spider. As a group, their long-legs, dark hairy bodies and preference for houses and buildings make them unmistakeable.Distribution
Widespread.Did you know?
Female house spiders can live for several years, and both males and females can survive for months without eating or drinking.
