I just saw a terrifying, many-legged creature racing across my basement floor. It looks almost prehistoric, with long, enormous antennae. Should I be concerned about it?

The frantic visitor was a house centipede, a many-legged arthropod commonly found in damp, dark spaces. Despite its alarming appearance, it generally avoids people and hunts smaller household pests, including silverfish, cockroaches, and spiders. Its extraordinary legs make it look intimidating, but spotting one is rarely a reason to panic. Bites are uncommon, usually associated with handling or trapping it against skin, and typically cause localized pain or irritation rather than serious harm.
