House Spider
The body ranges up to 3/8-inch in length, with a spherical abdomen. Typically brown or tan with various markings. "House" spiders are those web-building spiders common in the corners and garages of most homes and buildings.
|
Aggressive House Spider
Measures up to 3/4-inch in length and has a leg span measuring more than 1-1/2 inches. Color is usually brownish gray with a number of various markings. It is very difficult to distinguish it from its close relatives, the domestic house spider and the giant house spider (which do not have a dangerous bite).
|
Agressive House Spider Bite
If a person accidentally traps the spider against his or her skin, the spider bites out of defensive reflex. Unfortunately, the hobo spider's bite may result in an ulcerating wound similar to that of the brown recluse spider. Allowing the bite to become infected only increases the potential skin damage. Any person receiving any perceived spider bite should consult a physician for treatment.
