Ingredients You Will Need

• Food-grade diatomaceous earth – 1 cup (120 grams)
• Boric acid – 1/2 cup (60 grams)
• Essential oils (such as lavender, peppermint, or cedar) – 10-15 drops
• Water – 2 cups (480 milliliters)
• Spray bottle (16 oz / 480 ml capacity)
• Vacuum cleaner
• Sealant or caulk
• Containers for trapping silverfish (like glass jars)
• Old newspapers or cardboard (for trapping)

Step-by-Step Instructions

1. Prepare the Diatomaceous Earth Mixture: In a bowl, mix 1 cup of food-grade diatomaceous earth with 10-15 drops of your chosen essential oil. This mixture will serve as a natural insecticide.
2. Apply the Mixture: Using a duster or your hands, sprinkle the diatomaceous earth mixture in areas where you've noticed silverfish activity, such as behind appliances, in corners, and along baseboards.
3. Make the Boric Acid Solution: In a spray bottle, combine 1/2 cup of boric acid with 2 cups of water. Shake well until the boric acid dissolves completely.
4. Spray the Affected Areas: Lightly spray the boric acid solution in the same areas where you applied the diatomaceous earth. This will help eliminate any existing silverfish and deter new ones.
5. Set Up Traps: Take a few glass jars and fill the bottom with a small amount of water. Place these traps in areas frequented by silverfish. The insects will crawl in and drown.
6. Use Old Newspapers or Cardboard: Lay out old newspapers or cardboard in infested areas. Silverfish are attracted to the starch in paper and will gather there. Dispose of the paper once you've trapped them.
7. Vacuum Regularly: Use a vacuum cleaner to remove any silverfish, eggs, or debris from your home. Be sure to empty the vacuum bag or canister outside to prevent reinfestation.
8. Seal Entry Points: Inspect your home for cracks and crevices. Use sealant or caulk to close off these potential entry points, preventing silverfish from entering your home.
9. Maintain Low Humidity: Silverfish thrive in moist environments. Use a dehumidifier or air conditioner to keep humidity levels low, ideally below 50%.
10. Monitor and Repeat: Check traps regularly and repeat the application of diatomaceous earth and boric acid solution as necessary until you no longer see signs of silverfish.

Frequently Asked Questions (FAQs)

1. Can I use other essential oils instead of lavender, peppermint, or cedar?

Yes! Other essential oils such as tea tree or eucalyptus can also be effective. Just ensure they are safe for your environment.

2. How do I store the diatomaceous earth and boric acid mixtures?

Store any leftover mixtures in airtight containers in a cool, dry place. Always label the containers clearly and keep them out of reach of children and pets.

3. Are there any variations to this recipe?

Yes, you can customize the essential oils based on your preference or availability. You can also make traps using different types of containers, such as bowls with a few drops of oil to attract silverfish.

4. How often should I check the traps?

Check the traps daily for the first week. Once you notice a decrease in silverfish activity, you can reduce the frequency to weekly checks.

5. What should I do if I have a severe infestation?

If you suspect a serious infestation, consider consulting with a pest control professional for thorough treatment options.
