How to Identify Brown Spider with Two White Spots Under Abdomen

As arthropods, spiders are classified under the order Araneae. Accurately identifying a specific species is helpful in determining the level of danger associated with a given spider, and there are a number of reliable Internet sites that provide detailed information, complete with photos of spiders, to aid in determining which kind you are dealing with. If you discover that the spider does not pose a threat to humans or animals, consider leaving it alone. Not only do spiders eat pesky bugs and insects, but in some cultures, it is considered good luck to have a spider take up residence in your home.
