House spiders are cobweb spiders. Cobweb spiders refer the form of web that is created by the spider to capture its prey. House spiders and other cobweb spiders create a mass of tangled web strands that looks like a complete mess. While their webs might look unsightly, those random strands are extremely effective. When a prey insect walks past, it gets tangled in the strands. As it tries to escape, it comes into contact with even more strands and gets tangled up even more. The movements of the trapped insect send vibrations through the sticky webs and the house spider comes out to secure its next meal. House spiders come in a range of colors. They can be dark brown, or have chevron like marking across their bodies. They have a large abdomen with a smaller cephalothorax. The house spider is not out to bite you, but will if it feels threatened. Bites from a house spider can be painful, but are not medically significant. Still though, if you get bit by any spider you should always attempt to capture the spider so it can be identified if you begin to experience any strange symptoms like headaches or shortness of breath.
