Natural Ways to Get Rid of Silverfish

Natural Ways to Get Rid of Silverfish

If you're dealing with silverfish in your home, there are plenty of natural, safe, and effective ways to eliminate silverfish without using harsh toxins, such as diatomaceous earth. We’ll cover the best natural remedies, homemade traps and prevention tips so you can get rid of silverfish naturally while keeping your home safe for people and pets.

Why Choose Natural Remedies?

  • Safe for children and pets
  • Eco-friendly and biodegradable
  • Often less expensive than commercial insecticides
  • Easy to apply using everyday household items

Many natural methods work just as well, if not better when used consistently and combined with good cleaning habits.

1. Diatomaceous Earth

Diatomaceous earth (DE) is a powder made from fossilized algae. It kills silverfish by damaging their exoskeleton and drying them out.

  • Use food-grade DE only
  • Apply a thin layer behind baseboards, under sinks, and in closets
  • Leave for several days, then vacuum and reapply if needed

DE is non-toxic but dusty so best to wear a mask while applying.

2. Essential Oils

Silverfish are repelled by certain essential oils. Try mixing a few drops with water and spraying in areas where you've seen activity.

  • Lavender oil – calming for humans, irritating to bugs
  • Lemon oil – smells fresh and repels insects
  • Cedarwood oil – disrupts silverfish scent trails
  • Tea tree oil – antibacterial and antifungal

Reapply weekly or after cleaning.

3. Citrus Peels

Silverfish dislike citrus. Use fresh lemon or orange peels to discourage them in drawers and corners.

  • Place peels in mesh bags or cotton pouches
  • Replace every 1–2 weeks
  • Wipe surfaces with lemon juice and water for added scent

4. Cloves and Bay Leaves

These herbs are natural deterrents. Place them in corners, cupboards, or inside bookshelves where silverfish like to hide.

  • Use whole cloves or bay leaves
  • Replace monthly or when scent fades
  • Combine with lavender sachets for extra effect

5. Sticky Traps

Sticky traps made with natural glue can help monitor and reduce populations.

  • Buy non-toxic traps from eco-friendly brands
  • Place them along baseboards, behind toilets, or under furniture
  • Check and replace regularly

You can also make homemade sticky traps using index cards and honey or petroleum jelly.

6. Baking Soda and Sugar

This simple mixture attracts and kills silverfish naturally.

  • Mix equal parts sugar and baking soda
  • Place in shallow lids or bottle caps near infestation sites
  • Replace every few days

7. Salt

Salt dehydrates silverfish and their eggs.

  • Sprinkle around baseboards, under sinks, or along window sills
  • Vacuum and reapply weekly

Use as part of a broader cleaning and drying routine.

8. Declutter and Dry Out

In addition to using natural remedies, make your home less inviting to silverfish:

  • Use a dehumidifier in damp rooms
  • Fix leaks under sinks or behind walls
  • Keep books, papers, and fabrics off the floor
  • Vacuum regularly, especially near baseboards

Removing their food, water, and shelter is the most effective long-term strategy.

Getting rid of silverfish doesn’t mean reaching for toxic chemicals. With a little effort and some natural solutions, you can create a silverfish-free home that’s safe for your family and the environment. Try one or several of the remedies listed above and stay consistent. Most importantly, keep your home dry and clutter-free to stop silverfish from coming back.
