Millipedes are slow-moving arthropods known for their long, segmented bodies and numerous tiny legs. Despite their creepy appearance, millipedes are generally harmless to humans and pets. They thrive in moist environments and are commonly found in gardens, basements, and crawl spaces. Their primary diet consists of decaying plant material, making them more of a nuisance than a threat.
Millipedes typically enter homes seeking shelter and moisture, especially during heavy rains or when outdoor temperatures fluctuate drastically. If you notice them indoors, it’s usually a sign that your home has high humidity or organic debris attracting them.
Signs of a Millipede Infestation
Recognising the early signs of a millipede problem can help you take action before they multiply:
- Seeing several millipedes indoors, especially in damp areas
- Finding dead millipedes near baseboards or windows
- A musty odour, especially in crawl spaces or basements
- Moisture buildup around walls, foundation, or plumbing
Are Millipedes Harmful?
Millipedes aren’t poisonous and don’t bite. However, some species can release a defensive fluid that may cause mild skin irritation or allergic reactions. While they don’t pose a danger, their presence can indicate underlying moisture problems and contribute to poor indoor air quality over time.
Why You Should Try Home Remedies First
Home remedies are:
- Safe for kids and pets
- Eco-friendly – no harsh chemicals
- Cost-effective – most ingredients are already in your pantry
- Accessible – easy DIY solutions
Trying home remedies first makes sense for low-risk infestations and promotes healthier living conditions.
Top 10 Home Remedies to Get Rid of Millipedes
1. Diatomaceous Earth
This natural powder cuts through millipedes’ exoskeletons, drying them out. Sprinkle it around baseboards, under sinks, and near cracks.
Pros: Non-toxic, long-lasting
Tip: Reapply after vacuuming or moisture exposure.
2. Essential Oils (Tea Tree, Peppermint, Eucalyptus)
Millipedes hate strong smells. Mix 15-20 drops of essential oil with water and spray in high-traffic areas.
Bonus: Leaves your home smelling fresh!
Use caution around pets, especially cats.
3. Vinegar Spray
Mix equal parts white vinegar and water. Spray along entry points and infested areas.
Why it works: Alters the pH and discourages nesting.
Pro tip: Add a few drops of lemon juice to mask the strong smell.
4. Boric Acid
While slightly stronger, boric acid dehydrates millipedes and damages their digestive systems.
Use sparingly around pets or children.
5. Garlic Spray
Millipedes detest garlic’s sulphur compounds. Crush 5–6 cloves into hot water, let sit overnight, then spray where needed.
It’s natural, potent, and doubles as a pest deterrent.
6. Sticky Traps
DIY or store-bought sticky traps capture wandering millipedes overnight.
Place them in dark, humid areas like basements, closets, or under sinks.
7. Dehumidifiers
Millipedes crave moisture. A dehumidifier reduces air dampness, making your home less inviting.
Bonus: Also prevents mould and mildew growth!
8. Seal Entry Points
Use caulk, weather stripping, or mesh to block tiny cracks around doors, windows, and vents.
Focus on ground-level access points.
9. Baking Soda and Salt
A 50/50 mix of baking soda and salt is a desiccant blend that dries out millipedes.
Spread it along baseboards and in damp corners.
10. Yard Maintenance
Trimming overgrown vegetation and clearing leaf piles reduces millipedes’ outdoor habitats.
Keep gutters clean and mulch at least 6–12 inches away from the foundation.
How to Prevent Future Millipede Infestations
Once you’ve successfully removed millipedes from your home, the next step is keeping them out for good. Prevention is key, and with a few proactive steps, you can drastically reduce the chance of another infestation.
Keep Moisture Under Control
Millipedes thrive in damp environments. Use these tips to keep your home dry:
- Install a dehumidifier in basements and crawl spaces.
- Fix leaky faucets and pipes promptly.
- Ensure bathrooms and laundry areas are well-ventilated.
- Clean gutters regularly to prevent water buildup around the foundation.
Improve Drainage Around Your Home
Poor outdoor drainage can lead to standing water that attracts millipedes.
- Grade your landscape so water flows away from the house.
- Add gravel or sand to areas where water pools.
- Keep mulch, compost, and woodpiles far from your home.
Seal Cracks and Gaps
Check for cracks around windows, doors, pipes, and the foundation. Seal them with:
- Silicone caulk
- Weather stripping
- Expanding foam for larger gaps
Declutter Indoors
Reduce hiding spots for millipedes by:
- Clearing clutter in closets and basements
- Storing items in airtight plastic bins instead of cardboard
- Regularly vacuuming corners and under furniture
Common Mistakes to Avoid When Using Home Remedies
Even the best home remedies won’t work if used incorrectly. Watch out for these common errors:
Mistake | Why It’s a Problem | How to Fix It |
---|---|---|
Not identifying the source | You’ll keep treating symptoms, not the cause | Inspect for moisture issues |
Overusing essential oils | Can irritate pets or family members | Use diluted sprays in moderation |
Ignoring outdoor areas | Millipedes often come from your yard | Maintain a clean and dry perimeter |
Applying remedies once | Infestations may need repeated efforts | Be consistent and monitor results |
Mixing chemicals unknowingly | Can cause toxic reactions | Stick to one remedy at a time |
When to Call a Professional
If millipedes continue to appear despite your best efforts, it may be time to call a pest control expert. Here’s when you should consider it:
- You notice hundreds of millipedes indoors or outdoors
- Home remedies aren’t working after 2–3 weeks
- The infestation causes stress or impacts daily life
- There’s significant water damage or mould growth in your home
Professionals can identify hidden entry points, treat areas inaccessible to you, and provide long-term prevention plans.
FAQs About Getting Rid of Millipedes
What attracts millipedes to a house?
Millipedes are drawn to moisture, organic debris, and dark, quiet places. Damp basements, leaky pipes, and decaying leaves around the house all act like magnets for them.
Can millipedes bite or harm pets?
No, millipedes don’t bite. However, some species can secrete a defensive fluid that may cause mild irritation or allergic reactions if touched or ingested by pets.
How long does it take to get rid of millipedes with natural remedies?
With consistent use, most home remedies begin to show results within a week. However, complete eradication may take 2–3 weeks, especially in humid environments.
Are chemical repellents more effective than home remedies?
Chemical repellents may work faster, but often contain toxins harmful to pets and children. Home remedies are safer and more sustainable for long-term control.
What time of year are millipedes most active?
Millipedes are most active in the spring and fall, especially after heavy rain when the ground becomes saturated and they seek shelter indoors.
Can millipedes infest walls or furniture?
Millipedes don’t nest in walls or furniture like some pests. They prefer moist areas and often wander indoors accidentally, then die off quickly if they can’t find suitable conditions.
Conclusion: Take Control with Natural Remedies
Millipedes may be unsightly and annoying, but with the right strategies, you can easily keep them at bay. By using home remedies like diatomaceous earth, vinegar, garlic spray, and essential oils, you’re opting for safer, non-toxic alternatives that truly work. Remember, prevention is just as important—keeping your home dry, clean, and sealed will go a long way in protecting it from future infestations.
Start with simple steps, monitor results, and don’t hesitate to bring in professional help if the problem grows beyond your control. Your home should be a sanctuary—free from creepy crawlers and excess moisture alike.
