Effective Tips on How to Get Rid of Silverfish in Your Home

Silverfish are small, wingless insects that are found in many households. They can be a nuisance for homeowners because they feed on books, paper, glue, and other household items. Although silverfish do not pose any significant health risks, having an infestation can be frustrating and costly. These pests can reproduce quickly, making it challenging to get rid of them once they have settled in your home. Fortunately, there are several ways to identify and eliminate silverfish infestations. In this blog post, we will cover everything you need to know about these pesky creatures, including their behavior, habitat, signs of infestations, prevention tips, and effective ways to get rid of them. Whether you prefer natural remedies or chemical treatments, this comprehensive guide has got you covered.

Understanding Silverfish and Their Habitat

What are Silverfish?

Silverfish are small, wingless insects that belong to the Thysanura order. They are typically silver or gray in color with a slender, elongated body that ranges from 0.5 to 1 inch in length. These insects are known for their distinctive teardrop-shaped bodies and three long bristles on their rear end.

One of the most noticeable characteristics of silverfish is their movement pattern. They have a distinctive wiggling motion when they move, which is caused by their numerous legs. These insects are also nocturnal, so they tend to be more active at night.

In terms of diet, silverfish are known for their ability to consume a wide range of materials. They can feed on cellulose-based items, such as books, paper, and cardboard, as well as fabrics, sugars, and even human hair. Their diet makes them particularly problematic for homeowners, as they can cause significant damage to household items.

Despite their name, silverfish are not fish at all. The name ‘silverfish’ comes from their appearance, which resembles that of a fish’s scales. These insects have been around for over 400 million years, making them one of the oldest insect species in the world.

In conclusion, silverfish are interesting and unique pests that can cause significant damage to homes and belongings. Understanding their characteristics and diet is essential for effective control and prevention measures. If you suspect a silverfish infestation in your home, it’s best to contact a pest control professional for assistance.

Where Do Silverfish Live?

Silverfish are a type of wingless insect that thrives in humid and warm environments. They can be found all over the world, but they’re particularly common in areas with moderate to high humidity levels. As for their habitat, silverfish prefer dark and damp places where they can find food and shelter.

In homes, silverfish can be found living in a variety of places, including basements, bathrooms, kitchens, and laundry rooms. They tend to seek out areas with moisture, such as leaky pipes or areas that have suffered water damage. Silverfish are also attracted to starchy materials like paper, clothing, and wallpaper glue, making them a pest in libraries, museums, and other archives.

Outdoors, silverfish can be found in a range of natural habitats, including forests, fields, and damp soil. They often live under decaying leaves or bark, in rock crevices, and under fallen logs. In general, they prefer to live in cool, moist conditions, which is why they are often found near streams and rivers.

Silverfish are known to be resilient insects that can survive in harsh environments. They can even withstand long periods of starvation. However, they do have a preferred temperature range between 70 and 80 degrees Fahrenheit. When temperatures rise above or fall below this range, they become less active and may even die. As a result, you may find fewer silverfish during the winter months when indoor heating systems decrease humidity and lower the temperature.

Overall, silverfish can thrive in a variety of habitats, as long as they have access to moisture and food sources. By understanding their preferred living conditions, you can take steps to prevent them from infesting your home and eliminate any existing silverfish populations.

Behavior of Silverfish

Behavior of Silverfish

Silverfish are known for their unique behavioral patterns, which make them stand out from other pests. Below are some important aspects of silverfish behavior:


Silverfish are nocturnal creatures, meaning that they are most active during the night time. They prefer to hide in dark and damp places during the day, such as attics, basements, and bathrooms. At night, they venture out to search for food, water, and mates.


Silverfish move in a very distinctive way. They wiggle back and forth when they move, which gives them a fish-like appearance. They can also move very quickly, despite their small size. This makes it difficult for humans to catch or kill them.


Silverfish reproduce quickly, with female silverfish laying up to 20 eggs at a time. The eggs hatch in about three weeks, and the young silverfish can reach adulthood within three months. This rapid reproduction cycle means that silverfish infestations can grow rapidly if left unchecked.

Understanding the behavior of silverfish is an essential step towards preventing and eliminating infestations. By knowing their habits, you can take steps to remove their food sources, seal off their hiding places, and use effective treatments to eliminate them. So, if you see any signs of silverfish in your home, it’s essential to take action quickly to avoid a full-blown infestation.

Signs of a Silverfish Infestation

Signs of a Silverfish Infestation

Silverfish are nocturnal insects that can go unnoticed for long periods of time. However, if you know what to look for, there are several signs that may indicate an infestation in your home.


One of the most obvious signs of a silverfish infestation is actually seeing them scurrying across the floor or walls. They often move quickly and erratically, making them hard to catch. If you start seeing them during the day, this could be a sign of a severe infestation.

Another sign of an infestation is finding their droppings, which look like small black pepper-like pellets. You may find these under baseboards, in closets, or around areas where they feed.

Silverfish also shed their skin as they grow, leaving behind small translucent flakes that may be found in corners or near cracks and crevices. The more you find, the more likely it is that there is an active infestation.


If you have identified any of these signs, it’s possible that you have a silverfish infestation. These pests can cause damage to your home by feeding on paper products, fabrics, and even wallpaper paste. If left untreated, they can cause significant damage over time.


The type of damage caused by silverfish depends on what they feed on. In general, they prefer starchy substances such as paper and glue. They may chew holes in books, clothing, and wallpaper, causing unsightly damage. They can also invade food storage areas and contaminate dry goods.

It’s important to take action if you suspect a silverfish infestation in your home. The longer you wait, the more damage they can cause. In the next section, we will discuss some steps you can take to prevent and eliminate silverfish from your home.

Preventing Silverfish Infestations

Keeping Your Home Clean

Keeping your home clean is one of the best ways to prevent a silverfish infestation. These pests thrive in damp and dirty environments, so keeping your living space clean and dry can help deter them from taking up residence in your home. Here are some key strategies for keeping your home free of silverfish:


Regular vacuuming can help remove dust, debris, and food particles that may attract silverfish. Be sure to vacuum carpets, rugs, and upholstery, as well as any cracks or crevices where silverfish might hide. You should also vacuum under furniture and behind appliances, as these areas can accumulate dust and debris over time.


Dusting regularly can help remove cobwebs, dead insects, and other debris that might attract silverfish. Be sure to dust all surfaces, including shelves, baseboards, and light fixtures. You can use a microfiber cloth or feather duster to gently remove dust and debris without causing damage.


Cluttered spaces provide silverfish with plenty of hiding places, so it’s important to keep your home organized and tidy. Use storage containers and shelving to keep items off the floor and out of sight. Avoid storing cardboard boxes or paper bags in damp areas like basements or bathrooms, as these materials can become a breeding ground for silverfish.

By following these tips for keeping your home clean, you can reduce the risk of a silverfish infestation and create a healthier living environment for you and your family. Remember, the key is to stay vigilant and keep your living space clean and dry at all times.

Reducing Humidity Levels

Reducing Humidity Levels

High humidity levels attract silverfish and make your home a more hospitable environment for them. To discourage these pests, it’s important to maintain a dry and well-ventilated living space. There are several effective methods for reducing humidity levels in your home.


A dehumidifier is an appliance that removes moisture from the air. It works by pulling in humid air and passing it over a cool surface, which causes the moisture to condense and collect in a container or drain. Dehumidifiers come in various sizes, ranging from small portable units to large whole-house models. They can be particularly useful in areas of your home that are prone to dampness, such as basements or bathrooms.


Proper ventilation is essential for maintaining healthy indoor air quality and reducing excess moisture. This can include opening windows, running exhaust fans, and using air conditioning systems. Ventilation helps to circulate the air and remove odors, pollutants, and excess moisture. It’s also important to avoid blocking vents or air ducts with furniture or other objects, as this can restrict airflow and increase humidity levels.

Sealing Cracks

Cracks and gaps in your home’s walls, floors, and foundation can allow moisture to seep in, creating a breeding ground for silverfish. Sealing these openings can help to reduce humidity levels and prevent infestations. Some effective sealing materials include caulk, weatherstripping, and foam insulation.

By following these methods for reducing humidity levels, you can create a less favorable environment for silverfish and keep them from invading your home. Remember to monitor the humidity levels regularly and adjust your methods accordingly to maintain a dry and comfortable living space.

Getting Rid of Silverfish

Natural Remedies

Natural Remedies

If you’re looking for a more natural way to get rid of silverfish, there are several remedies you can try that are safe for both humans and pets. Here are three effective options:

Boric Acid

Boric acid is a natural insecticide that can be used to kill silverfish. It works by damaging the insect’s exoskeleton, causing it to dehydrate and die. To use boric acid, simply sprinkle a small amount in areas where silverfish are known to hide, such as under sinks, in cabinets, or behind appliances. Be sure to keep the powder away from children and pets since it can be harmful if ingested.

Diatomaceous Earth

Diatomaceous earth is a fine powder made from the fossilized remains of tiny aquatic organisms called diatoms. It’s non-toxic and safe for humans and pets but deadly to insects like silverfish. When sprinkled in areas where silverfish are present, the powder sticks to their bodies and damages their exoskeleton, causing them to dehydrate and die. Diatomaceous earth can be found in most garden centers or online.

Essential Oils

Essential oils like lavender, cedar, and citrus can be used to repel silverfish. These oils have a strong odor that silverfish find unpleasant, so they’ll avoid any areas scented with them. To use essential oils, mix a few drops with water in a spray bottle and mist problem areas such as baseboards, corners, and cracks. You can also add a few drops of essential oil to cotton balls and place them in drawers or cabinets to deter silverfish.

While these natural remedies can be effective, they may not completely eliminate a silverfish infestation. For severe infestations, it’s best to combine natural remedies with other treatments or call in a professional exterminator for assistance.

Chemical Treatments

Chemical Treatments

Chemical treatments are another way to get rid of silverfish infestations. This method involves using pesticides, insecticides, sprays, and traps to eliminate these pests. However, it is important to use these chemicals with caution, as they can also harm humans and pets.


Insecticides are a popular choice for eliminating silverfish. They come in various forms, including liquid, powder, and aerosol sprays. These products contain chemicals that are specifically designed to target and kill silverfish. It is essential to follow the instructions carefully when applying insecticides, as overuse or misuse can be dangerous.


Sprays are a common chemical treatment for silverfish infestations. These products contain chemicals that act as both a repellant and a poison to silverfish. Sprays can be used in specific areas where silverfish are present, such as cracks and crevices. However, it is important to use sprays with caution, as they can also harm other beneficial insects that may be present in your home.


Traps are another chemical treatment option for getting rid of silverfish. These sticky traps are designed to attract and capture silverfish. They work by luring silverfish with bait and then trapping them on the sticky surface. While traps can be effective, they may not be suitable for larger infestations.

It is important to note that chemical treatments should be used as a last resort, after all other methods have been exhausted. If you do choose to use chemical treatments, it is essential to read and follow the instructions carefully. Additionally, consider hiring a professional exterminator who can safely and effectively eliminate silverfish from your home.

Calling in the Professionals

Calling in the Professionals

While DIY methods and natural remedies can be effective for removing small silverfish infestations, larger or more severe cases may require the help of a professional exterminator. Pest control companies are equipped with the necessary tools, knowledge, and experience to identify and eliminate silverfish colonies quickly and efficiently.

When choosing a pest control company or exterminator, it’s important to do your research. Look for companies with experience in dealing with silverfish specifically, as well as those that use safe and eco-friendly practices. Make sure they are licensed and insured to protect yourself from any potential damages or liability.

The cost of hiring a professional exterminator can vary depending on the severity of the infestation, the size of your home, and the type of treatment used. In general, expect to pay anywhere from $100 to $300 for a one-time treatment. Some companies may also offer ongoing maintenance plans for an additional fee.

While the cost may seem high, calling in the professionals can save you time and money in the long run. A thorough extermination by a trained professional can eliminate the entire colony, preventing future infestations and potential damage to your home.

In summary, if your silverfish infestation is beyond your control or if you want to ensure a thorough and effective removal, don’t hesitate to call in the professionals.
