How to Get Rid of Centipedes: A Comprehensive Guide
Centipedes, with their numerous legs and rapid movements, can be unsettling to find in your home. While they are generally harmless to humans and even beneficial as predators of other insects, their presence can be unnerving. If you’re looking to rid your home of these multi-legged creatures, this comprehensive guide provides detailed steps and instructions to effectively eliminate centipedes and prevent their return.
## Understanding Centipedes
Before diving into eradication methods, it’s essential to understand what attracts centipedes to your home. Centipedes thrive in damp, dark environments where they can find food, typically other insects. Common attractants include:
* **Moisture:** Leaky pipes, poorly ventilated areas, and standing water create ideal conditions.
* **Food Source:** The presence of other insects (e.g., spiders, ants, cockroaches) provides a food source.
* **Shelter:** Dark, undisturbed areas like basements, crawl spaces, and under piles of debris offer shelter.
* **Entry Points:** Cracks and crevices in foundations, walls, and around pipes provide easy access to your home.
## Step 1: Identification and Assessment
First, confirm that you’re dealing with centipedes and assess the extent of the infestation. Common types include:
* **House Centipedes (Scutigera coleoptrata):** These are the most common indoor centipedes. They have long, slender bodies, 15 pairs of legs, and move very quickly. They are yellowish-brown with dark stripes. They are typically nocturnal.
* **Garden Centipedes (Lithobiomorpha):** These are typically found outdoors in gardens and under rocks, but may occasionally wander indoors. They are generally smaller and darker than house centipedes.
Once you’ve identified the type, look for signs of infestation:
* **Sightings:** Regularly seeing centipedes, especially in damp areas.
* **Moist Areas:** Focusing your search in bathrooms, basements, crawl spaces, and under sinks.
* **Other Insects:** A pre-existing insect problem, as centipedes prey on them.

* **Manage Outdoor Moisture:**
* **Clear Gutters:** Clean gutters regularly to prevent water from accumulating and overflowing near your foundation.
* **Direct Water Away from Foundation:** Ensure that downspouts direct water away from your home’s foundation to prevent water from seeping into the basement or crawl space.
* **Grade Soil Away from Foundation:** Make sure the soil around your foundation slopes away from the house to promote water runoff.
* **Address Standing Water:**
* **Remove Standing Water:** Eliminate any standing water around your property, such as in flower pots, bird baths, or puddles.
* **Maintain Swimming Pools and Hot Tubs:** Properly maintain swimming pools and hot tubs to prevent mosquito breeding and excess moisture.
## Step 4: Sealing Entry Points
Preventing centipedes from entering your home is crucial. Seal any cracks, crevices, or openings that they might use to gain access.
* **Inspect and Seal Cracks:**
* **Foundation Cracks:** Inspect your foundation for cracks and seal them with caulk or concrete sealant.
* **Wall Cracks:** Seal cracks in walls with caulk or patching compound.
* **Window and Door Frames:** Seal gaps around window and door frames with caulk or weatherstripping.
* **Seal Openings Around Pipes and Wires:**
* **Caulk Openings:** Seal openings around pipes, wires, and cables that enter your home with caulk or expanding foam.
* **Use Steel Wool:** Stuff steel wool into larger openings before caulking to prevent pests from chewing through the sealant.
* **Install Door Sweeps:**
* **Install Door Sweeps:** Install door sweeps on exterior doors to prevent centipedes and other pests from crawling underneath.
* **Repair or Replace Damaged Screens:**
* **Check Window and Door Screens:** Inspect window and door screens for tears or damage and repair or replace them as needed.
## Step 5: Using Insecticides (Judiciously)
While reducing moisture and eliminating food sources are the most effective long-term solutions, insecticides can provide immediate relief. Use them cautiously and follow all label instructions carefully.
* **Perimeter Sprays:**
* **Apply Insecticide Around Foundation:** Apply an insecticide spray around the perimeter of your home, focusing on areas where centipedes might enter.
* **Choose the Right Insecticide:** Use an insecticide labeled for crawling insects, such as those containing pyrethrins, pyrethroids (e.g., cypermethrin, deltamethrin), or bifenthrin.
* **Follow Label Instructions:** Always follow the manufacturer’s instructions for application rates, safety precautions, and reapplication intervals.
* **Indoor Sprays:**
* **Spray Cracks and Crevices:** Spray insecticide into cracks, crevices, and other areas where centipedes might hide, such as baseboards, under sinks, and in closets.
* **Use a Residual Insecticide:** Choose a residual insecticide that provides long-lasting control. Avoid spraying surfaces that come into contact with food or children’s toys.
* **Dusts:**
* **Apply Insecticide Dusts:** Apply insecticide dusts, such as diatomaceous earth or boric acid, into cracks, crevices, and other inaccessible areas.
* **Diatomaceous Earth:** Diatomaceous earth is a natural, non-toxic option that kills centipedes by dehydrating them. Apply a thin layer in areas where centipedes are likely to travel.
* **Boric Acid:** Boric acid is a mild insecticide that is effective against a variety of pests. Use it sparingly and keep it out of reach of children and pets.
**Important Safety Precautions When Using Insecticides:**
* **Read and Follow Label Instructions:** Always read and follow the manufacturer’s instructions for application rates, safety precautions, and storage.
* **Wear Protective Gear:** Wear gloves, a mask, and protective clothing when applying insecticides to avoid skin contact and inhalation.
* **Ventilate the Area:** Ensure adequate ventilation when applying insecticides indoors to avoid inhaling harmful fumes.
* **Keep Children and Pets Away:** Keep children and pets away from treated areas until the insecticide has dried or settled.
* **Store Insecticides Safely:** Store insecticides in a secure location out of reach of children and pets.
* **Consider Professional Pest Control:** If you have a severe or persistent centipede infestation, consider hiring a professional pest control company.
## Step 6: Natural and DIY Remedies
If you prefer a more natural approach, several DIY remedies can help deter centipedes.
* **Diatomaceous Earth (DE):**
* **How it Works:** DE is a naturally occurring substance made from the fossilized remains of diatoms (a type of algae). It’s non-toxic to humans and pets but deadly to insects. DE works by absorbing the oils and fats from an insect’s exoskeleton, causing it to dehydrate and die.
* **Application:** Sprinkle a thin layer of food-grade DE in areas where you’ve seen centipedes, such as along baseboards, in cracks and crevices, and around entry points. Reapply after it gets wet.
* **Safety:** Use food-grade DE, as pool-grade DE can be harmful if inhaled.
* **Boric Acid:**
* **How it Works:** Boric acid is a naturally occurring compound that acts as a stomach poison and desiccant for insects. When centipedes ingest or come into contact with boric acid, it disrupts their digestive system and dehydrates them.
* **Application:** Sprinkle a thin layer of boric acid in areas where you’ve seen centipedes, such as along baseboards, in cracks and crevices, and around entry points. Be careful not to use too much, as it can be harmful if ingested.
* **Safety:** Keep boric acid out of reach of children and pets.
* **Vinegar:**
* **How it Works:** Vinegar, especially white vinegar, is a natural disinfectant and cleaning agent. Its strong acidic properties can deter centipedes and other insects.
* **Application:** Mix equal parts of white vinegar and water in a spray bottle. Spray the solution in areas where you’ve seen centipedes, such as along baseboards, in cracks and crevices, and around entry points. You can also use vinegar to clean floors and surfaces to eliminate centipede attractants.
* **Essential Oils:**
* **How They Work:** Certain essential oils, such as peppermint, eucalyptus, and tea tree oil, have insect-repellent properties. They can disrupt an insect’s nervous system or mask the scent of food sources, deterring them from entering your home.
* **Application:** Mix 10-20 drops of essential oil with water in a spray bottle. Spray the solution in areas where you’ve seen centipedes, such as along baseboards, in cracks and crevices, and around entry points. You can also soak cotton balls in essential oil and place them in areas where centipedes are likely to hide.
* **Safety:** Be cautious when using essential oils around pets, as some oils can be toxic to animals.
* **Citrus Peels:**
* **How They Work:** Citrus peels, such as lemon, orange, and grapefruit peels, contain compounds that are toxic to insects. When centipedes come into contact with these compounds, it can disrupt their nervous system and kill them.
* **Application:** Place citrus peels in areas where you’ve seen centipedes, such as along baseboards, in cracks and crevices, and around entry points. Replace the peels every few days as they dry out.
* **Bay Leaves:**
* **How They Work:** Bay leaves contain compounds that are toxic to insects. When centipedes come into contact with these compounds, it can disrupt their nervous system and kill them.
* **Application:** Place bay leaves in areas where you’ve seen centipedes, such as along baseboards, in cracks and crevices, and around entry points. Replace the leaves every few weeks.
## Step 7: Preventative Measures
Once you’ve eliminated the centipedes, take steps to prevent them from returning:
* **Maintain a Clean Home:** Regularly clean and declutter your home to eliminate food sources and hiding places for centipedes.
* **Reduce Moisture:** Maintain low humidity levels in your home by fixing leaks, improving ventilation, and using dehumidifiers.
* **Seal Entry Points:** Seal cracks and crevices in your foundation, walls, and around pipes and wires to prevent centipedes from entering your home.
* **Trim Vegetation:** Trim shrubs and bushes around your home’s foundation to reduce moisture and provide less harborage for centipedes.
* **Clear Debris:** Remove piles of leaves, wood, and other debris from around your home to eliminate potential hiding places for centipedes.
* **Regular Pest Control:** Consider regular pest control treatments to prevent centipede infestations and other pest problems.
