The Giant house spider is indigenous to north western Europe.

The webs built by the Giant house spider are flat and messy with a funnel at one end.

Giant house spiders may compete with hobo spiders for the same resources.

Tegenaria duellica (giant house spider)

The Giant house spider has the same coloration as the Domestic house spider; it has earthy tones of brown and muddy red or yellow.

His essay "April in Paris" documents his growing affection towards and domestic association with Giant House spiders, particularly one named April.

A population of Giant house spiders is popularly thought to be a deterrent to the establishment of Tegenaria agrestis, known in North America as the hobo spider, and considered by some to be more likely to bite humans.

The hobo spider is a resident of fields, rarely entering human habitations due to the presence of major competitors, particularly the giant house spider (Tegenaria duellica) which is a common resident of houses and other man-made structures in Europe.

The Giant house spider (Tegenaria duellica; sometimes also referred to as T. gigantea) is a member of the genus Tegenaria and is a close relative of both the Domestic house spider and the infamous Hobo spider.

Recent arachnological studies, however, suggest that the species had a common ancestor with the giant house spider that spread to both Europe (through Asia) and the rest of North America from Northwestern Canada (possibly from a region currently including British Columbia) long before the first human settlement in North America.
