House spiders are common arachnids found in many homes around the world. They typically have long legs and small bodies, and they can vary in color from brown to gray. These spiders are beneficial as they help control pest populations by feeding on insects like flies and mosquitoes. Most house spiders prefer dark, undisturbed areas such as corners, basements, and attics. They build webs to catch their prey, although some species, like the jumping spider, do not spin webs and actively hunt instead. House spiders are generally harmless to humans and can even be helpful in maintaining a balanced ecosystem indoors.
