Silverfish are tiny insects that are typically not dangerous to people, yet they can cause harm to belongings. They do not bite or sting, nor are they recognized as carriers of diseases. Nonetheless, an outbreak of silverfish can harm items such as clothing, carpets, furniture, soft construction materials, paper, and books. Additionally, having silverfish in the home may worsen reactions to other allergens.
A small number of silverfish can help keep a balanced insect population in your home. They consume predatory arthropods like spiders and will even feed on deceased silverfish. Therefore, encountering a single silverfish doesn’t always warrant extermination. However, if you notice a significant number of them, it may indicate a silverfish infestation that requires action. Here are some methods to eliminate silverfish.
What are Silverfish?
Silverfish (Lepisma saccharina) are diminutive, wingless insects with six legs, measuring approximately 3/4 inch in length. They possess a shiny, metallic silvery-gray hue. Their movements resemble those of fish, which is why they are also referred to as fish moths. Additionally, they are known as bristletails due to the three tail-like appendages located at the end of their bodies.
Silverfish typically consume starches, proteins, and fibers, which include various natural fabrics. When present in significant quantities, they can damage textiles within a household, showing a preference for older garments and carpets. These items are especially at risk due to their composition, which often consists of natural fibers that attract silverfish.
Silverfish feed on cashmere garments and velvet coats. They can also damage books and paper documents by gnawing on the adhesive used in older publications. Additionally, they consume household glue and specific types of paint.
Indicators of a Silverfish Infestation
Silverfish are tiny creatures, yet they can cause significant harm due to their rapid reproduction. Promptly recognizing and tackling an infestation is crucial to prevent these pests from wreaking havoc in your home. Keep in mind that silverfish tend to avoid bright light, so they may be less visible during the day, especially on overcast days.
Here are some signs that indicate you may have a silverfish problem:
- Frequent observations of silverfish insects.
- Feeding marks, characterized by uneven punctures on textiles and various surfaces.
- Yellow marks or droppings resembling small black pepper grains on various surfaces.
6 Methods to Eliminate Silverfish
Upon identifying a silverfish problem, it’s important to act quickly to eliminate it. You should thoroughly clean every surface in your house, paying special attention to your clothes and bedding.
Perform a comprehensive cleaning.
- Carefully clean all garments, linens, and other fabric items, including curtains.
- Clean carpets and area rugs by shampooing them in accordance with the instructions on the care label.
- Clean upholstered furniture with a vacuum, ensuring to reach beneath the cushions.
Dust with Diatomaceous Earth.
- Apply it to your floors, particularly in spots where silverfish are often spotted.
- Allow it to sit for 24 hours, keeping it dry, and then proceed to vacuum.
- Use cedarwood spray to deter them.
Encase Them in Crystal
- Apply tape to the exterior of a glass jar filled with starchy food items.
- Once they step inside, escape will be impossible.
- Seal the jar tightly and eliminate the silverfish from your living space.
Capture Them on Paper
An alternative method for trapping silverfish involves taking a rolled-up newspaper and lightly misting it with water. The silverfish will be attracted to it and will settle inside. After a few days, simply throw away the newspaper.
Utilize Boric Acid
Boric acid is used similarly to diatomaceous earth by scattering it in the affected areas. This pesticide effectively eliminates silverfish on contact. Nevertheless, it poses potential risks to children and pets, so it is advisable to explore alternative solutions before using it.
Employ a Pest Control Specialist
If you’re dealing with a serious pest problem, it may be necessary to enlist the help of a professional. While exterminators can be quite effective, they often rely on chemical pesticides to eliminate the issue.

What Leads to a Silverfish Infestation?
There are multiple reasons why silverfish may invade your living space. These pests are drawn to damp and humid environments within your house, including:
- Bathrooms
- Kitchens
- Basements
- Vulnerable areas (such as a compromised section of the roof or the window casing)
Silverfish tend to gather and create nests in areas where food is abundant. Their primary source of nourishment is cellulose, a carbohydrate found in materials like paper, textile fibers, and shed skin, including dandruff.
- Dust
- Grains
- Dehydrated meats (such as jerky and animal feed)
- Vintage literature and periodicals
- Fibers derived from natural fabrics
Ways to Avoid a Silverfish Infestation
There are several effective and safe methods to avoid a silverfish bug infestation in your house.
Lower Humidity
- Whenever feasible, open windows to allow fresh air to flow through.
- Utilize heated towel rails to decrease humidity levels in the atmosphere.
- Consider acquiring a dehumidifier.
- Activating fans to ensure proper air circulation.
- Store silica gel packets in drawers or cabinets to help minimize humidity, ensuring they are kept away from children and pets.
Eliminate Dust
- Regularly dust or vacuum to minimize the dust that serves as food for silverfish.
- For wooden floors, use a broom followed by a damp mop with a soap that is oil-based.
- Regularly shake out your rugs, preferably outdoors.
Reduce the Amount of Clutter
- Avoid accumulating cardboard for recycling, as the glue can attract silverfish.
- Dispose of outdated books or clothing that you won’t use anymore.
Seal Grain Goods
- Store all grain-based items, such as pasta, rice, cereals, and flour, in airtight glass containers or resealable plastic bags.
- Remove any food debris that lands on the floor, countertop, or makes its way into the pantry or cabinets.
Seal Open Spaces
If there are openings in your window frames, think about using caulk to fill them in. Additionally, caulking is an effective solution for any irregular gaps in the attic that are exposed to the outdoors, as these could allow silverfish to enter.
Repel Them Using Cedarwood
- Create a spray by combining 10 drops of cedarwood essential oil with 4 ounces of water, and remember to shake it lightly before each application.
- Apply the spray in moist areas such as corners, closets, and around bookshelves. Additionally, consider treating your rugs and upholstery with the spray.
- An alternative approach involves applying essential oil to multiple cotton balls placed in an open glass vessel, like a votive candle holder, and positioning it in a location where the fragrance can disperse into the surrounding air.
Give Bay Leaves a Try
- Grind dried bay leaves into smaller pieces.
- Secure them in muslin pouches.
- Store them in drawers, wardrobes, and nooks.
