The House Centipede in Your Bathroom May Be Hunting Something Worse

If a house centipede ran across your bathroom tonight, would you kill it? The legs are real, the speed is real, and the panic is understandable. But this animal may be running toward something you want in your home even less: young cockroaches, flies, silverfish, and even spiders are all on its recorded prey list. This video follows the house centipede (Scutigera coleoptrata) from the tile floor up. Fifteen pairs of legs on a body about three centimeters long, the last pair reaching past the antennae. Speeds reported at half a meter per second or more, which for this body is more than ten body lengths every second. A hunter that ignores prey moving nearby until something touches it, then wraps its legs around the catch like loops of rope. A pair of venom-delivering limbs under the head that centipede biologists call forcipules. Then the harder questions. What is actually on the menu, and why the word nymphs matters. Whether it can hurt a person (University of Kentucky specialists call the bite hazard minimal, and Connecticut's entomology guide says human envenomation is very rare and tied to rough handling). Why a leg comes off so easily, how the replacement grows coiled inside the base of the old one, and why the number of pairs climbs from four at hatching to fifteen. And the reason not to call every sighting good news: a predator does not stay where there is nothing to hunt. Repeated sightings can point to moisture and a steady supply of small arthropods behind the wall. Killing the one you can see removes the clue, not necessarily the conditions. Entomology guides recommend reducing moisture and sealing cracks and entry points.
