Appearance Brown recluse spiders are around 6-20 mm in length and can grow larger. These spiders are typically light to medium brown, but some can range in color from white-ish to dark brown or blackish gray. Habitat Brown recluse spiders build irregular webs that can be found in woodpiles, sheds, closets and cellars. They prefer dark, enclosed areas to build their webs. These spiders are hunters, their web isn't for catching prey, but they roam around searching for their prey. You can find brown recluse spiders in the central southern part of the United States. Entry and Damage Brown recluse can rarely bite unless they feel threatened. It's hard to identify a brown recluse bite as they usually show within a few hours, but most bites will become red and then fade away. However, there are some cases when tissue damage may occur. You should seek medical help immediately if you have concerns. Contact a Critter Control of Seattle expert today if you find a brown recluse spider near your home.
