What Causes Silverfish Infestation And How To Get Rid of Them

Like many common household pests, silverfish can be more problematic in the springtime when the temperatures start to rise. However, if the indoor conditions are right, silverfish can invade your home and damage many of your belongings, including priceless ones, at any time.

Food and Water

Common household pests infest homes because they find it easier to have access to food and water, two of their basic needs, indoors than outdoors. This is true in winter, where food tends to be scarce.

Your home is attractive to silverfish because it has everything that silverfish love to eat. They range anywhere from books, clothes, carpets, insulation materials to dry pet food.

Silverfish: Good, Bad, or Just Ugly

Silverfish also love snacking on pantry items. Eating food contaminated with or has silverfish won’t endanger your health alright.

But it’s very disgusting.

Many of the things that silverfish prefer to eat the most are belongings that are priceless and irreplaceable. Some common examples are photographs and artworks.

Silverfish also eat hair and skin flakes on the scalp.

So, if you have dandruff, put it under control ASAP!

Moisture, Warmth and Darkness

The presence of food and water is not enough to cause a silverfish infestation to come into being.

The environment also needs to be ideal for silverfish to survive. When it comes to picking the perfect home to invade, silverfish look for three very important things.

They are:

  • Moisture. It’s for this reason why bathrooms tend to attract lots of silverfish.
  • Warmth. Silverfish hate the cold. They prefer to live where the temperature ranges from 70°F to 90°F, which means they like a little heat. However, silverfish can survive temperatures below 50°F.
  • Darkness. Being nocturnal animals, silverfish like to stay where there is little to no light available.

Do you have a silverfish infestation and want to get rid of those scaly critters through the DIY way? You can increase your success rate by focusing on areas of your home that are moist, warm and dark.

Water Leaks or Floods

Just because you do not live where it’s hot and humid doesn’t mean that you should not worry about silverfish that are hooked on excess moisture.

Failure to keep your home in tip-top shape can invite silverfish to live in it.

For instance, a leaky pipe can cause water to be present where it should not exist.

This can make the area so favorable for silverfish. Improper floor or wall sealing and a leaky gutter can cause floods, too, leading to increased moisture levels.

Needless to say, it will make your home more delightful for silverfish.

Besides silverfish, water leaks or floods can also attract other common household pests. Some of them are centipedes, cockroaches and ants. Unnecessary moisture can also cause mold and mildew to form.

Lack of Cleanliness

Many common household pests thrive so much better in dirty and messy homes. That’s because there are plenty of hiding and mating places available for them.

What’s more, scraps of food and beverage and sauce stains allow pests to enjoy their meals without the need to exert a lot of effort.

Silverfish are some critters that are attracted to filthy homes — it makes keeping their tummies full easier.

The importance of keeping your home clean and clutter-free after dealing with a silverfish infestation cannot be stressed enough. Otherwise, it is very much likely for you to go through the same problem again.

Secondhand Transmission

In some instances, a silverfish infestation can start without some silverfish crawling inside the home to feed, mate and nest.

There are cases where the problem can be due to the unintentional introduction of silverfish into the home.

Buying secondhand books, artworks, sofas and other items infested with silverfish without your knowledge can welcome some silverfish into your life.

Once inside your home, silverfish will have no problem feeding on and nesting in your belongings. Shopping from a questionable grocery store can also cause silverfish transmission.

It doesn’t take a lot of silverfish for a serious silverfish infestation to happen because these pests multiply fast.

For instance, one female silverfish can lay two to three clusters of eggs per day, and each cluster can have up to 20 eggs!

The takeaway: A silverfish infestation can be due to many things. Allowing a couple of silverfish into your home is enough for a serious silverfish infestation to start.

That’s because they can grow in numbers fast. And because silverfish can live up to eight years, failure to deal with them can leave you with a headache for a very long time.

How to Get Rid of Silverfish

No matter the common household pest causing mayhem on your home and indoor living, it is of utmost importance that you deal with the problem as soon as you learn about its presence.

This can keep pests multiplying further and causing more damage to your property and belongings.

When it comes to getting rid of pests, you got two options:

  • Get in touch with a local pest control company. Allowing the experts to spring into action is an effective way to solve the infestation with as little to no complications as possible. Alas, professional extermination doesn’t come free of charge. Most of the time, it doesn’t come cheap, too.
  • Deal with the infestation via home remedies. Many homeowners who wish to save money opt for the DIY approach because it is cheaper. Most of the time, the products or ingredients needed are already in their homes, usually in their kitchens. Sadly, for a serious infestation, home remedies may fail to impress.

Each option comes with its own set of pros and cons.

When choosing which approach is best for the situation, consider certain things. They include the pest involved, level of infestation, damage caused, and available budget.

Although it is important that you think things over, you should come up with a decision before the problem gets out of hand.

If you prefer to get rid of a silverfish infestation with your own two hands, there are many steps that you may take. But first, let us answer some important questions related to eliminating silverfish via the DIY way…

Here are the things you may try to have a silverfish-free home…

Sprinkle Diatomaceous Earth

Many small insects die upon contact with diatomaceous earth. They include silverfish. This is why you may count on it if you want to eliminate silverfish from your home without professional help.

It may sound like it contains some potent and toxic ingredients.

However, diatomaceous earth is 100% natural.

It is made from the fossilized shells of diatoms, which are single-celled organisms living in lakes, rivers, and other bodies of water. Diatomaceous earth works by dehydrating silverfish until they breathe their last.

Something as simple as sprinkling diatomaceous earth on hotspots is enough to help you put a silverfish infestation under control.

However, avoid sprinkling it in wet places. That’s because diatomaceous earth stops working when moist.

Online, you can get your hands on diatomaceous earth trouble-free. Here are some of the best-sellers:

DiatomaceousEarth DE10

Because it’s 100% pure diatomaceous earth and listed with the Organic Minerals Research Institute (OMRI), too, it doesn’t come as a surprise why Diatomaceous Earth.com Food Grade Diatomaceous Earth sells like hotcakes.

Primarily, the product is for dealing with high cholesterol levels and constipation. It is also for improving the health of the skin, nails and hair. But if your home has silverfish, you may rely on it to get rid of those pests.

For best results, sprinkle generous amounts of Diatomaceous Earth.com Food Grade Diatomaceous Earth where you see silverfish.


Harris Food-Grade Diatomaceous Earth

Like the product above, Harris Food-Grade Diatomaceous Earth is also pure and organic. However, what makes it a standout is that its plastic container has a puffer tip for trouble-free application.

What’s really nice about this product (and other all-natural diatomaceous earth brands, too) is that it’s safe for use inside and outside the home.

In some instances, silverfish may infest gardens. Harris Food-Grade Diatomaceous Earth may be used to get rid of silverfish in garden pots and boxes without harming plants and the environment.

Just a word of caution: Food-grade diatomaceous earth is non-toxic to humans and pests. However, consider using another solution for silverfish if you have an indoor cat or dog.

That’s because they may inhale large amounts of diatomaceous earth by accident, which can irritate their airways and lungs.


Try Epsom Salt

Besides diatomaceous earth, you may also try Epsom salt. It works in the same fashion — Epsom salt dehydrates silverfish until they can survive no more.

With regular application, you can put a silverfish infestation under control.

Epsom salt is the perfect alternative to diatomaceous earth as a silverfish natural killer if you have a pet.

The worst thing that could happen to your cat or dog is diarrhea since Epsom salt has a laxative effect. However, this should be the least of your worries since Epsom salt is unpalatable to pets as it’s quite bitter.

But just like diatomaceous earth, Epsom salt works best if it’s kept dry. This is why you should use it in combination with other all-natural remedies for a silverfish infestation.

Install Glue Traps

If you are on the hunt for a tip on how to stop silverfish from eating clothes and other belongings of yours, look no further. One of the best ways on how to stop silverfish on their tracks is by installing glue traps.

Also known as “glue boards”, glue traps are small boards coated with an adhesive. They are designed to trap crawling and even flying insects.

Most glue traps in the market are for beetles and moths. Worry not because they are also very good for trapping silverfish. As a matter of fact, they are excellent at trapping just about any small insects.

To make glue traps your ultimate silverfish extermination tools, place bits of bread in the center of each sticky board. This will attract silverfish to crawl through them.

But be warned: baiting glue traps with bread can cause other pests to get trapped, too, which is a good thing if you want a pest-free home.

Let’s check out two of the top-selling glue traps on the internet:

Trapper Monitor & Insect Glue Traps

Use Cedar Shavings or Oil

Keeping silverfish from coming back is just as important as killing them. It’s because of this why you should also include silverfish repellents in your arsenal of weapons.

As the name says, repellents work by fending off silverfish. They are effective for protecting some of your belongings from silverfish and preventing an infestation.

  • Bed bugs
  • Carpet beetles
  • Moths
  • Cockroaches
  • Ants

To keep some nooks, crannies and spaces off-limits to silverfish, all you have to do is sprinkle some cedar shavings on them. Just remember to replace them with fresh cedar shavings every three to six months for best results.

While effective for driving silverfish away, cedar shavings can cause quite a mess. Fret not because you can also count on cedar chips or blocks, which are less likely to get dispersed than cedar shavings.

You may also use cedar oil instead, which you can apply by spraying or wiping on silverfish-prone areas.

Spray Lavender Essential Oil

Lavender essential oil is effective for reducing stress, relieving anxiety and promoting a good night’s sleep.

However, for silverfish, the lavender essential oil is bothersome. Its smell drives away those scaly and shiny pests.

It’s because of this why lavender essential oil is one of the most effective all-natural remedies for silverfish. It cannot kill them alright.

However, it can keep them from wreaking havoc on your belongings and life, too. The best lavender essential oil for silverfish prevention is the kind that’s 100% pure and therapeutic grade.

That’s because it can affect the way your meals smell and taste. Besides spraying, you can also use lavender essential oil by diffusing it with a diffuser or burner.

Switch on a Dehumidifier

It was mentioned earlier that one of the things that attract silverfish to homes is moisture.

Needless to say, keeping the moisture levels inside your home less ideal for silverfish can help put the infestation to an end. It can also help keep another silverfish infestation from striking.

First things first: If leaky pipes or gutters and poor drainage are the causes of excess moisture indoors, get them fixed. Then you may start counting on some cheap and effective ways to absorb excess moisture. Something that works each time is placing a bowl of charcoal, baking soda or chalk in the room where there’s plenty of moisture.

But if you are serious about dealing with silverfish, use a dehumidifier. This is true during summer when it’s hot and humid. As the name suggests, a dehumidifier is an appliance that removes moisture from indoor air.

Online, there are so many dehumidifiers to choose from. Here are some of those worth your attention:

Alrocket 35-Ounce Dehumidifier

It’s true that silverfish can infest just about any area of the home. However, it’s rare for them to infest the entire home at the same time — silverfish prefer damp and dark environments only.

This is when the benefit of having the Alrocket 35-Ounce Dehumidifier comes in. Its compact body makes it easy to take it from room to room.

The dehumidifier has a 35-ounce tank capacity. Per day, it can collect up to 60 ounces of water in the air inside your home. Because of its quiet motor, the Alrocket 35-Ounce Dehumidifier is great for a 260-square-foot bedroom.


Lonove 27-Ounce Portable Dehumidifier

Despite being small, the Lonove 27-Ounce Portable Dehumidifier can remove up to 12 ounces of water a day as it has two air inlets.

It’s not just space that it saves but electricity, too. That’s because it has auto start and shut-off features.


Ask Termite Pest Control Company to Fumigate

Fumigation kills silverfish. It is rare for pest control companies to offer silverfish fumigation service. However, those that offer termite fumigation can fumigate silverfish, too. Unfortunately, fumigation to kill silverfish requires evacuation of the home for the duration of the treatment.

Fumigation can help put a silverfish infestation to an end alright. However, it’s not the most practical choice.

Apply Heat Treatment

Silverfish cannot stand high temperatures. This is why heat treatment can help put an end to a silverfish infestation. One treatment is more than enough to kill both adult and larvae silverfish as well as the eggs. Dry, hot air is more effective than direct heat as silverfish can hide very well.

Heat treatment doesn’t come cheap. It can cost anywhere from $300 t0 $2,500. The overall price of heat treatment will depend on different factors. They include the size of the home and the level of the silverfish infestation.

Use All Natural Insecticides

Many insecticides are effective for dealing with a silverfish infestation. Some are natural, and they can be either bought at hardware or home improvement stores or made in the kitchen. Others have chemicals that may cause complications, which is why their use is best left in the hands of the pros.

If you are planning to control a silverfish infestation on your own, consider using all-natural insecticides.

Now that those silverfish extermination-related questions have been answered, it is time to discuss some of the most effective ways to get rid of silverfish.

If you want to free your home of a silverfish infestation without contacting a local pest control company, it is a good idea to opt for steps that are proven effective.
