I was ready to squash it without hesitation—a quick swipe at that unsettling bug darting across my bathroom floor.
But something about its lightning speed, delicate legs, and eerie silence made me pause. That “gross critter” wasn’t just any pest—it might actually be the unsung hero protecting my home from a full-blown cockroach invasion. What I discovered changed how I view house centipedes forever—and it might surprise you, too.
Centipedes are unmistakable thanks to their elongated, segmented bodies, dozens of legs, long antennae, and tiny venomous jaws.
Their color varies from pale yellow to deep brown, and while their appearance can be creepy, there’s more to these creatures than meets the eye.
Depending on the type, a centipede can sport anywhere from 15 to 77 pairs of legs, allowing them to zip effortlessly across floors—and even climb walls.
Can Centipedes Bite?
Yes, they can bite and inject venom, but for humans and pets, their bites are rarely serious. Expect some mild pain, redness, or swelling if bitten, but dangerous reactions are extremely uncommon.
Still, most of us aren’t thrilled to find one in our homes. Before you reach for that shoe or bug spray, here’s why you might want to reconsider.
Five Little-Known Facts About Centipedes
More Legs Over Time — Centipedes actually gain more legs as they grow older and molt. If they lose legs, they can regrow them through successive molts.
Ancient Survivors — These creatures have roamed the Earth for over 400 million years, making them one of the oldest land animals alive today.
Lightning Fast Movers — Don’t underestimate their speed. They can dash across surfaces at over a foot per second, thanks to their many legs and flexible bodies.
Voracious Hunters — Centipedes aren’t picky eaters. While smaller species snack on insects and worms, bigger ones can tackle prey like spiders and even small frogs.
Long Lifespan — Some species, including the common house centipede, can live for up to six years or more under ideal conditions.
Though fascinating, most people would prefer to keep these speedy predators out of sight.
Who Preys on Centipedes?
Centipedes aren’t at the top of the food chain. Birds, mice, frogs, snakes, beetles, and some spiders hunt them, especially younger or slower individuals. Interestingly, larger centipedes can even prey on frogs and spiders themselves.
Why You Should Think Twice Before Killing House Centipedes
Spotted a house centipede indoors? Before you react, know that these creatures are valuable natural pest controllers. They hunt down cockroaches, spiders, termites, and other unwanted bugs invading your space.
Unlike other pests, centipedes don’t nest or cause property damage. Their presence often signals a reduction in more destructive insect populations.
However, if centipedes start appearing in large numbers, it might indicate an underlying pest problem needing professional intervention. While a few centipedes can be beneficial, a large infestation means it’s time to call an expert.
Some house centipedes can live up to a decade—so unless you want a long-term creepy roommate, managing their numbers is key.
Final Thought:
House centipedes may give you the creeps, but they’re often more helpful than harmful. Next time you see one scuttling across your wall, think twice before smashing it—they might just be quietly protecting your home from worse pests.
