House centipedes may look intimidating, but they’re harmless to people and actually helpful. They feed on roaches, silverfish, and other insects, keeping pest populations under control without the need for harsh chemicals. Unlike termites or rodents, they don’t damage property, food, or wiring, and bites are extremely rare and mild. If you notice them often, it could mean you already have other pests in your home—so reducing moisture, sealing cracks, and keeping things clean can help keep both centipedes and their prey in check.
