Diatomaceous earth is a natural silverfish killer

Diatomaceous earth is a proven and natural silverfish killer.

It penetrates the exoskeletons of silverfish and absorbs their bodily fluids, triggering their deaths by internal dehydration. 

So, scatter a generous amount of diatomaceous earth in your closet. 

It’ll be best to push the powder inside the nooks, corners, and gaps, as some silverfish can be hiding in them, too.

As usual, don’t forget to scatter the dust inside the drawers of the closet. 

Diatomaceous earth is not an instant insect killer. It takes time to kill them.

So, please wait a few hours to let it do its work.

Clean the closet thoroughly without skipping the corners. 

Dispose of the vacuum dust bag after vacuuming, as you did in the second step. 

Seal Any Cracks In The Closet

Clothing storages, such as wardrobes and closets, develop cracks and gaps. 

Those crevices become the hiding places for bugs. 

Caulk those gaps with a quality sealant, preferably silicon-based sealant. These sealants are rigid, and bugs can’t chew through them. 

Restock The Closet With Clean Clothes

That’s it, you’re done. It’s time to restock your closet with your clothes. 

But the game isn’t over. These bugs can come back.

Preventing Silverfish In The Closet

Prevent Silverfish In The Closet

For any DIY bug treatment, preventative measures are more crucial than elimination methods. 

You’ll need to take specific steps that are safe for your clothes to prevent silverfish and other closet bugs from returning. 

Spray Cedar Wood Oil

Affluent homeowners build their entire closets and wardrobes from cedar wood because of its bug-repellent qualities. 

But you don’t have to. 

Instead, you can use cedar oil spray thrice weekly to keep silverfish and other fabric bugs away from your closet. 

For the same effect, you can also use cedar wood chips and balls to keep them in the closet and inside the dresser drawers. 

Studies have shown that cedar has repellent qualities that keep bugs like ants, silverfish, and even ticks away. 

Keep Your Expensive Clothes In Garment Hanging Bags

Many fabric pests, such as the carpet beetle larvae and silverfish, target natural fibers such as wool, silk, cotton, leather, feathers, and fur to feed on them. 

Keep the clothes made from natural fibers in vinyl hanging bags to prevent these bugs from accessing your expensive fabric. 

Silverfish Traps

There are sticky silverfish traps that are readily available. You can keep a few in the corners of the closet. 

The traps lure the silverfish, and they get stuck on them if they crawl on the traps. 

Silverfish are nocturnal insects. So, it’ll be best to keep the traps during the night.

Dispose of the traps if you find any silverfish stuck on them the following day.

Control Humidity

Silverfish are moisture bugs. They enter homes from outdoors, looking for damp areas in the house. 

If silverfish were in your closet, chances are your closet and your home have moisture issues. 

Fix leaky pipes in your bathroom, kitchen, basement, and laundry room. 

Water leakages are responsible for increasing the dampness levels of the house.

Keeping a dehumidifier inside the closet significantly reduces moisture. A dry closet, without mold, doesn’t attract silverfish.

Hire Professional Pest Control

The presence of silverfish in the closet is a clear sign of silverfish present in other areas of your house. 

Maybe there’s a silverfish infestation in the house that you’ve been ignoring. 

As they’re creatures of night, it’s hard to detect silverfish during the day. That leads to a spike in infestation quickly. 

Chances are the silverfish in the closet are spilling over from places like the bathroom and kitchen, where they prefer to hide. 

And from these areas, silverfish can also end up on your bed.

It’ll be best to hire a professional pest controller to eliminate silverfish because these pests can be hard to eliminate. 

Silverfish Damage To Clothes

Silverfish will chew on clothes and leave behind holes and yellow stains.

These holes are irreparable and the yellow stains, their fecal stains, can be hard to remove.

Silverfish don’t bite, and they don’t spread any diseases. 

But silverfish can cause harm to stored foods in the kitchen, clothes, books, and taxidermies.

They can also leave behind their fecal matter and shed skin, which can cause allergies in sensitive individuals.


For natural silverfish control in the closet, vacuum extensively and use diatomaceous earth, a natural silverfish killer.

You can also use silverfish spray if you want to use chemicals. But read the safety instructions before using it.

It’s essential to take preventative measures to keep silverfish away from the closet.

You can do it using natural repellents such as cedar or peppermint oil and controlling moisture.
