What Kills Centipedes? Your Ultimate Guide to Centipede Control

Centipedes, those creepy-crawly arthropods with numerous legs, can be unsettling houseguests. While they do prey on other insects and can be considered beneficial in some ways, most homeowners prefer not to share their space with them. So, what effectively kills centipedes? The answer depends on your preferred method – from natural remedies to chemical controls. Ultimately, whether you decide to get rid of them is up to you as they kill pests in your house that are completely unwelcome.

Here’s a comprehensive guide to help you tackle your centipede problem:

Methods for Eliminating Centipedes

1. Contact Insecticides: The Immediate Strike

Synthetic pesticides containing pyrethroids, such as bifenthrin or cypermethrin, are highly effective at killing centipedes on contact. These chemicals disrupt the nervous system of the centipede, leading to rapid paralysis and death.

• How to use: These insecticides are typically available in spray form. Apply directly to centipedes you encounter.
• Caution: Always follow the manufacturer’s instructions carefully. Use these products in well-ventilated areas and keep children and pets away during and after application until the treated surfaces are dry.

2. Residual Insecticides: Long-Term Control

For a more lasting solution, consider using residual insecticides like Avesta CS and Cyper WSP. These products leave a toxic residue that continues to kill centipedes for an extended period.

• How to use: Apply these insecticides along cracks and crevices, entry points, and baseboards where centipedes are likely to travel. Creating a 3- to 10-foot band around the perimeter of your home can also deter centipede activity.
• Caution: Like contact insecticides, residual insecticides should be used with caution. Read and follow the label instructions thoroughly.

3. Natural Pesticides: A Gentle Approach

If you prefer a more environmentally friendly approach, natural pesticides can be effective, although they may require more frequent application.

• Diatomaceous Earth (DE): This powder is made from fossilized algae. It damages the exoskeleton of centipedes, leading to dehydration. Sprinkle DE around areas where centipedes are commonly found. Be sure to use food grade diatomaceous earth.
• Boric Acid: This compound is another effective natural pesticide. It works similarly to DE, disrupting the centipede’s exoskeleton and digestive system. Apply it in areas where centipedes hide or travel.
• Important: When using DE or boric acid outdoors, research their potential impact on nearby plants.

4. Essential Oils: Aromatic Repellents and Killers

Certain essential oils possess properties that can repel or even kill centipedes. Tea tree oil and peppermint oil are particularly effective.

• How to use: Mix about 25 drops of either essential oil with 6 ounces of water in a spray bottle. Spray the mixture around door frames, windows, cracks, and basement doors. Repeat weekly for best results.
• Why it works: Centipedes find the scent of these oils overwhelming, and contact with the oil can be toxic to them.

5. DIY Vinegar Spray: A Direct Assault

White vinegar can be used to directly kill centipedes.

• How to use: Pour white vinegar into a spray bottle and spray it directly onto the centipedes. This method is effective but will require you to clean up the dead bugs afterward.

6. Creating an Unwelcoming Environment: Prevention is Key

The best way to control centipedes is to make your home less attractive to them in the first place.

• Reduce Moisture: Centipedes are drawn to damp environments. Fix any leaks, improve ventilation, and use a dehumidifier in damp areas like basements and bathrooms.
• Remove Hiding Places: Clear away clutter, such as boxes, piles of newspapers, and other debris, that can provide shelter for centipedes.
• Seal Entry Points: Seal cracks and crevices in your foundation, walls, and around pipes to prevent centipedes from entering your home.

7. Natural Predators: Letting Nature Take Its Course

Encouraging natural predators of centipedes can also help control their population.

• Outdoors: Shrews, toads, badgers, and birds, including domestic chickens, prey on centipedes.
• Indoors: Spiders and ground beetles may also hunt young centipedes.

Frequently Asked Questions (FAQs) About Centipedes

1. Why do I suddenly have centipedes in my house?

Centipedes are drawn to damp, humid environments and a readily available food source (other insects). Leaky pipes, cluttered basements, and an abundance of insects can all attract centipedes to your home.

2. Are centipedes dangerous to humans?

House centipedes are generally not dangerous to humans. They do possess venom, which they use to subdue their prey, but their bite is usually mild and rarely causes more than localized pain and swelling.

3. Do centipedes go on beds?

Centipedes can end up in beds, especially if there are other pests they can prey on in the room. Remove clutter around the room, and keep the room as dry as possible.

4. Should I kill centipedes, or are they beneficial?

Centipedes are beneficial in that they prey on other pests like roaches, moths, flies, silverfish, and termites. However, most homeowners prefer not to have them around. The decision to kill them depends on your personal preference.

5. What smell do centipedes hate?

Centipedes are repelled by the smell of peppermint and tea tree oil.

6. Does salt kill centipedes?

No, salt does not effectively kill or deter centipedes. While salt may dehydrate them, it’s not a reliable method for centipede control.

7. Do centipedes hate light?

Yes, centipedes prefer dark environments. Turning on a light can temporarily deter them, causing them to scurry back to hiding places. However, light alone won’t solve a centipede problem.

8. Will centipedes take revenge?

Centipedes are animals, and not capable of plotting revenge.

9. How do you know if you have a centipede infestation?

Signs of a centipede infestation include frequently seeing centipedes in your home, especially in damp areas. However, seeing centipedes may also indicate the presence of other pests that they are preying on.

10. Does vinegar repel centipedes?

Yes, vinegar will deter centipedes. Spray the vinegar directly at the centipedes.

11. What is a centipede’s weakness?

Centipedes are prone to dehydration. They lack the waxy coating that many other insects have, making them dependent on moist environments.

12. Do centipedes stay in one room?

Centipedes will move from room to room in search of food and suitable hiding places. They are more likely to stay in a room that offers both moisture and a readily available food source.

13. Do centipedes climb walls?

Yes, centipedes can climb walls and ceilings. They use their claws to grip small imperfections on surfaces.

14. What attracts centipedes to a home?

Centipedes are attracted to homes that offer moisture, dark hiding places, and a plentiful food source. Leaky pipes, cluttered basements, and the presence of other insects all contribute to a centipede-friendly environment.

15. What is the best repellent for house centipedes?

The most effective repellents for house centipedes are peppermint oil and tea tree oil. These oils are fragrant and can effectively deter centipedes from entering your home.
