Location

The giant house spider originated from the north western Europe and introduced to Pacific northwest of America through Vancouver in 1900 basically due to human inactivity.

Behavior

This kind of spider can create webs which are flat and messy and characterized by a funnel at one end. The spider waits in the funnel portion of the web for its prey until a small insect gets caught in the web. They build their webs normally in corners of the floor and ceiling, between boxes in basement, behind cupboards, in attics or in any area not frequented by large animals or humans.

Habitat

Giant house spiders are giant in a sense that they are the largest arachnid of the genus Tegenaria. They dwell in flowerbeds, wood piles and other sheltered, outdoor areas. They can also be found in dark crevices and basements. Some are found near shorelines or woods where they live beneath driftwood, rocks and logs. In the late summer and early autumn, male giant house spiders wander arrogantly to look for a mate.
