What Are the Identifying Characteristics of a House Spider?

Some characteristics that identify house spiders include a two-part body that is usually brown, black or gray; a length that is usually not more than a quarter inch; and eight eyes. They don't possess wings, and their presence can be detected by seeing their webs or some cobwebs. Some specific types include brown house spiders, southern house spiders and giant house spiders, states Orkin.

Another characteristic of house spiders is color rings on the legs and some abdomen spotting, notes the National Wildlife Federation. The rings on the legs are often darker in color, while the legs themselves can be a lighter color like orange or yellow.

Finally, another characteristic of house spiders is their eating habits. They tend to eat small insects like mosquitoes in the home.
