How to get rid of silverfish

Silverfish are common household pests that can be difficult to spot as they dart quickly across floors or walls. They thrive in damp, humid environments, and while they’re harmless to people, they can damage household items.

These insects are small and wingless, known for their silvery-gray scales and fast, darting movements.  As occasional invaders, they are pests that normally live outdoors but may come inside when conditions are right. They are often found in damp, dark areas of homes such as bathrooms, basements, and kitchens, where they can find moisture and food sources.

Silverfish are nocturnal, which means they usually hide during the day and come out at night to feed. Their diet includes starchy materials, making them a nuisance in homes where they can damage books, wallpaper, and clothing.

Methods to get rid of silverfish

The thought of tiny little silver insects crawling all over your bathroom, pantry, and closet can be enough to send you running to the phone to call pest control. Knowing how to treat silverfish naturally can help prevent these pests from entering your home in the first place. While pest control can help ensure that you are rid of these unwelcome guests, there are some steps you can take that can lighten your load of silverfish. Here are five ways to help prevent silverfish.

Silverfish enjoy wet areas and thrive in damp spaces, so lowering moisture levels is one of the most effective ways to control them. Using a dehumidifier, improving ventilation, or repairing leaks can make areas like bathrooms and basements less attractive. This method works best as a long-term prevention step rather than a quick fix. 

You will need to fix any leaking water around sinks, refrigerators or toilets. Any stagnant water can provide potential breeding grounds for silverfish.

Silverfish are sensitive to strong odors, so certain scents can help work as a natural deterrent. Mothballs can be placed in areas where silverfish have been spotted, though it’s worth noting they do not kill the insects; they simply help drive them away.

Spices such as sage, bay leaves, and cloves can also serve well as good repellents.

Silverfish make their way into your pantry for carbohydrate sources, their favorite snack. Seal all of your cereals and grains in plastic containers with airtight lids. While this won’t eliminate silverfish already in your home, it makes your pantry less appealing and helps protect your food.

Regular vacuuming is an effective way to reduce silverfish activity. It removes crumbs, dust, and other potential food sources, while also picking up eggs that may be hidden in carpets, cracks, or baseboards.

Chemicals such as boric acid can be used to help treat silverfish. However, this method has limitations: it requires careful placement, may not reach hidden populations, and can be risky in homes with children or pets. 

Because of these drawbacks, boric acid is generally far less effective than professional pest control services, which target the root of the infestation more thoroughly.

While the above methods may help reduce silverfish activity and prevent them in small numbers, they are not enough to eliminate an infestation. Only professional pest control can fully address the problem by targeting silverfish at the source and helping protect your home long-term.

Preventing future silverfish infestations

The best way to keep silverfish out of your home is to eliminate the conditions that attract them. Follow these prevention tips:

  • Control moisture and humidity: Use dehumidifiers or ventilation fans in bathrooms, basements, and laundry rooms to reduce dampness.
  • Fix leaks promptly: Repair dripping faucets, pipes, or condensation issues under sinks and behind walls.
  • Seal entry points: Close cracks and gaps around doors, windows, and foundations to block silverfish from sneaking indoors.
  • Store food securely: Keep cereal, flour, pet food, and other pantry items in airtight containers instead of open boxes or bags.
  • Limit cardboard storage: Unpack and recycle cardboard boxes quickly, and avoid storing paper products directly on the floor.

By tackling these areas, you’ll make your home less appealing to silverfish and greatly reduce the risk of an infestation.

Frequently asked questions

Silverfish prefer dark, damp areas. Inside homes, they’re often found in basements, bathrooms, laundry rooms, and kitchens. They can also hide in closets, attics, or storage boxes where humidity is higher and food sources like paper or fabric are available.

No. Silverfish do not bite, sting, or spread disease, so they are not harmful to people or pets. The biggest concern with silverfish is the damage they can cause to household items such as books, wallpaper, clothing, and stored food.

Silverfish are attracted to moisture, food sources, and shelter. Damp spots, leaky pipes, and high humidity create the right conditions for them. They are also drawn to starchy materials such as paper, glue, and fabric, as well as open food containers in pantries. In some cases, they may also hitchhike inside through cardboard boxes.

Signs of silverfish include spotting the insects themselves, especially at night, or finding feeding damage such as irregular holes in paper, books, or clothing. You may also notice yellowish stains, shed scales, or small pepper-like droppings near areas where they hide.

You can try using sticky traps and natural repellents, such as spices or mothballs, which can discourage silverfish or help monitor their activity. However, natural prevention methods rarely eliminate the problem entirely.  For long-term relief, contact a professional pest control provider.
