Impede the centipedes around your home
You know what they say about creepy-crawlies: More legs, more problems. And, aside from its distant relative, the millipede, the centipede takes the cake in that department. If you want to know how to rid this many-legged creature from your home, you’re not alone.
But while their exterior can be cringe-inducing, centipedes are generally harmless and often misunderstood. Whether or not you can sympathize, you probably aren’t a fan of the creatures stirring about your house. Here’s a little more detail on how to get rid of them (and why you might want to peacefully coexist).
Although they’re equally matched in (and arguably winning) the “creepy” contest, centipedes technically aren’t insects, but arthropods. They’re venomous but rarely cause harm to humans.
They’re also carnivores that feast on a variety of insects and other creepy critters, including:
Ants
Spiders
Moths
Cockroaches
Bed bugs
Silverfish
Crickets
Other centipedes
Although their name literally means “100 legs,” this isn’t a constant trait of the centipede. Each segment of their body contains one pair of legs (typically 15 pairs in total), which can roughly add up to 100 or more (or far fewer). These legs are usually quite long, protruding from their flat bodies and propelling them forward at freakish speeds.
Most centipedes, including the common house centipede, are orange or yellowish brown to dark brown in color and typically between 1 and 3 inches long. They have one pair of long, sensitive antennae and venomous jaws that they use to poison their victims. While they rarely bite humans, they can inflict a painful sting if provoked.
In fact, the National Capital Poison Center says centipedes are usually less dangerous than using bug spray.
If you’ve spotted the occasional centipede in your home, here’s some good news: They don’t nest in homes. Instead, they prefer to stay in active hunting mode, searching for annoying and/or terrifying insects to feed on, like roaches and bedbugs.
Centipedes are also bashful creatures that avoid confrontation with humans, so if you choose to leave them be, you likely won’t cross paths very often. Either way, here are the best ways to keep them out.
While poison sprays and swift squashes can be tempting, centipedes are beneficial insects—as such, trapping them and safely releasing them is the way to go. Centipedes are quick but mild-tempered and won’t try to attack unless you roughly handle them with your hands.
Best of all, you’ll have an outdoor ally that will continue to munch on insects, even if you can’t bear to share quarters with it.
Here’s an easy contact-free way to catch and release them back to the wild:
Place a cup or glass over the centipede.
Slide a magazine or a stiff piece of cardboard underneath.
Carry it outside and set it on the ground.
Lift the glass and allow the centipede to scurry away.
Centipedes need moisture to survive, along with a healthy selection of insects to eat. Dealing with moisture problems in your home will make it uninhabitable, while sealing off entry points will keep out centipedes and other pests.
Here are the best ways to make your home unappealing to centipedes:
Use a dehumidifier to address moisture problems.
Inspect and repair any broken door or window seals.
Use caulk or expanding foam to seal off any cracks and crevices.
Remove any firewood, organic debris, and leaf litter near your home.
If the catch-and-release method isn’t something you can get behind, you can seek more drastic measures.
Bug sprays with these ingredients will kill centipedes:
Cyfluthrin
Cypermethrin
Deltamethrin
Permethrin
Lambda-cyhalothrin
Tralomethrin
Take safety precautions when using bug spray—especially with kids and pets in the area. Open your windows and follow the manufacturer’s instructions. If you don’t want to go the poison route, sticky traps are another way to capture centipedes and remove them from your home. These have the added benefit of catching the other creepy-crawlies in your home, too.
If you want to get rid of centipedes for good, it’s crucial to address the one and only thing that invites them in the first place: food (aka any other creepy-crawly pests in your home). By keeping bugs out of your home, you’re making your place way less tempting, and they will most likely head out soon enough. As a bonus, you’ll also send spiders packing as well.
These are the best ways to reduce the bugs and spiders around your home:
Maintain a clean home (Pro tip: Use a daily, weekly, and monthly house cleaning checklist to help you stay on track).
Clean up food spills ASAP.
Keep all food in sealed containers.
Examine the perimeter of your home for cracks, gaps, and other potential entry points.
Consider using pest-deterring essential oils around your home (some can be dangerous to pets, so be sure to fully research what you use).
Despite the best DIY efforts, sometimes it’s time to call a local exterminator for help. Whether it’s ants, cockroaches, spiders, or other pests that have created a buffet for centipedes, a local exterminator is your go-to lifeline for eliminating them.
While there’s no need to kill centipedes, if you’re squeamish by the sight, an insecticide spray will kill them on contact (read the label first to ensure it will be effective on centipedes).
When using poison, always keep it away from children and pets and follow all of the manufacturer’s guidelines. Boric acid is a low-toxicity alternative, but it should still get placed where children and pets can’t access it.
A sudden onset of centipedes could point to moisture issues in your home. Take measures to reduce your home’s humidity and call in a local plumber to fix leaks ASAP.
