Spiders are as familiar and well known to most people as they are disliked. The unpopular reputation of spiders is undeserved. Myths about spiders and the negative consequences of biting by a very, very small number of species overshadow the ecological benefits spiders provide.
All spiders are beneficial predators that feed on insects, spiders, and other arthropods, and thus help reduce pest populations in and around homes, landscapes, gardens, and crops.
