Silverfish are one of the most annoying household pests. They hide in dark corners, bathrooms, kitchens, basements, and even inside books or closets. While they don’t bite, they can damage paper, clothes, wallpaper, and stored food. The good news is you don’t need harsh chemicals to deal with them. These Natural Ways to Get Rid of Silverfish methods are safe, effective, and easy to use at home.
1. Reduce Humidity in Your Home
Silverfish thrive in moist environments. Bathrooms, laundry rooms, and basements are their favorite spots because of high humidity. Use exhaust fans, open windows when possible, and run a dehumidifier in damp areas. Keeping humidity below 50% makes your home uncomfortable for silverfish and helps prevent future infestations.
2. Seal Cracks and Small Gaps
Silverfish often enter through tiny cracks around baseboards, door frames, and plumbing lines. Sealing these gaps with caulk blocks their entry points and removes hiding spots. This simple step also improves your home’s overall cleanliness and energy efficiency.
3. Use Diatomaceous Earth
Food-grade diatomaceous earth is one of the most effective natural pest solutions. Sprinkle a thin layer in corners, under sinks, behind appliances, and along baseboards. It works by damaging the silverfish’s outer layer, eventually dehydrating and killing them without chemicals.
4. Add Cedar to Closets and Storage Areas
Silverfish hate the smell of cedar. Placing cedar blocks, chips, or sachets in closets, drawers, and storage boxes naturally repels them. This method is especially useful for protecting clothes, books, and paper items.
5. Keep Floors and Corners Clean
Dust, crumbs, and paper debris attract silverfish. Regular vacuuming especially in corners, behind furniture, and under appliances removes food sources and eggs. Focus on areas that don’t get cleaned daily.
6. Use Baking Soda and Sugar Trap
Mix equal parts baking soda and sugar and place it in shallow containers near silverfish activity. The sugar attracts them, while the baking soda disrupts their digestive system. This is a simple, low-cost natural solution.
7. Try Natural Essential Oils
Silverfish dislike strong scents such as lavender, citrus, peppermint, and eucalyptus. Mix a few drops of essential oil with water and spray along baseboards, shelves, and bathroom corners. This not only repels pests but also keeps your home smelling fresh.
8. Remove Excess Paper and Cardboard
Old newspapers, magazines, cardboard boxes, and books stored in damp places are perfect silverfish food sources. Declutter regularly and store important papers in sealed plastic containers instead of cardboard boxes.
9. Fix Leaks Immediately
Leaky pipes and dripping faucets create moisture that attracts silverfish. Repairing leaks reduces humidity and removes one of their main survival needs. This step also prevents mold and water damage.
10. Store Food in Airtight Containers
Silverfish can feed on pantry items like flour, cereal, and dry goods. Use airtight containers to block access. This also helps keep your kitchen clean and organized.
11. Use Vinegar for Surface Cleaning
White vinegar works well for cleaning shelves, drawers, and bathroom surfaces. While it won’t kill silverfish instantly, it removes scent trails and discourages them from returning to treated areas.
12. Place Sticky Traps in Problem Areas
Sticky traps help monitor and reduce silverfish activity naturally. Place them near baseboards, under sinks, and inside cabinets. This method is chemical-free and helps identify infestation hotspots.
13. Keep Laundry Areas Dry
Silverfish often hide behind washing machines and dryers. After laundry, leave the area dry and well-ventilated. Avoid storing damp towels or clothes for long periods.
14. Use Bay Leaves as a Repellent
Bay leaves give off a smell that silverfish dislike. Place crushed bay leaves in cabinets, pantry corners, and storage bins. It’s a simple and safe natural repellent.
15. Improve Air Circulation
Good airflow helps reduce moisture buildup. Rearrange furniture slightly away from walls and use fans where airflow is poor. A dry environment naturally discourages silverfish.
16. Stay Consistent With Prevention
Natural methods work best when used consistently. Combining cleanliness, moisture control, and natural repellents ensures long-term results and keeps silverfish from returning.
Final Thoughts
Getting rid of silverfish naturally is completely possible with patience and the right approach. By reducing moisture, removing food sources, and using safe natural repellents, you can protect your home without harsh chemicals. These methods not only eliminate silverfish but also create a cleaner, healthier living space.
