Spiders leave tell-tale signs around the house.
The common house spider, or Achaearanea tepidariorum, usually isn't dangerous like its toxic cousins -- the brown recluse or the black widow. However, they can become a nuisance in your home. The common house spider will spin webs in barns, homes, basements and areas that are damp. While common house spiders don't usually bite people, they can. Because common house spiders can build extensive communities, they can be hard to get rid of. Does this Spark an idea?
Instructions
1. Locate webs in you home. Discover if the webs form irregular and tangled webs, advises the University of Arkansas Division of Agriculture. Common house spiders can produce several webs in a short time period.
2. Locate a spider if possible. Look for yellow to brown coloring on the upper portion of the spider, as noted by Penn State College of Agricultural Sciences.
3. Look at the abdomen of the spider. Common house spiders have bulbous-shaped abdomens with grayish colored chevrons, which are bracket-shaped markings. A common house spider's abdomen will be higher than it is in length.
4. Look at the legs of the spider you are trying to identify. Legs on a common house spider will appear yellowish to brown, with bands of black, segmented throughout the common house spider's legs.
5. Look for egg sacs. Female house spiders will lay many, brown colored egg sacs, in their webs. Each egg sac can contain hundreds of eggs.
