How to Get Rid of Silverfish



A silverfish is around 1/2′ long and it is silver. The body is long, slim, and flat. It is wide in the front but gets closer together at the end. Silverfishes moves extremely fast but once the silverfish finds a food source that it likes, it will tend to stay close to it. They are nocturnal so they are active at night or in dark places throughout the structure. An adult silverfish molts it skin throughout the year so it can be something useful in detecting silverfish. They can do damage to book bindings, wallpaper, paper goods, and dry foods. They might eat holes through the wallpaper to get to the glue or bite tiny holes in fabrics (i.e. cotton, linen, and even silk). Silverfish might leave a yellow stain on the fabrics.


Silverfish can be found in dark, moist, and moderate temperatures. You will find them under the sink, in basements, kitchens, closets, shelves, behind baseboards, window/door frame, wall voids, and laundry rooms. They like to eat wallpaper paste, natural textiles, books, and papers; they also consume fungi/mold.



  1. Fix any source that causes moisture like flawed plumbing or condensation because silverfishes are attracted to moisture.
  2. Dehumidifying will help reduce the moisture content in the air. Some ways you might help dehumidify are fixing leaking pipes, ventilate closed off rooms and attics, draining standing water, and using a dehumidifier air conditioners.
  3. Vacuum cracks and crevices with a narrow vacuum tip
  4. Remove food sources and store them in tight containers.
  5. Insulate your attic

Since silverfishes come in from the outside, you will need to treat outside to help prevent infestation inside.

You can treat silverfishes by liquid spray ( FenvaStar EcoCap) using a hand sprayer , granule (BIFEN GRANULARS) using a hand spreader (HANDLE SPREADER), aerosol ( ALPINE AEROSOL), dust (PYGANIC DUST) using a duster (BELLOW BULB DUSTER) and station (DEKKO SILVERFISH PACKS).

For outdoor treatment, you will need to use a liquid spray (FenvaStar EcoCap) with a hand sprayer that has a mist nozzle tip (CHAPIN 1 GALLON SPRAYER), and granule (BIFEN GRANULARS ) using a hand spreader (HANDLE SPREADER).

Using the amount instructed on the label and apply it around your structure uniformly. This treatment is called a barrier treatment or also known as a perimeter treatment. This treatment will create a barrier around your home to prevent silverfishes from coming into your home.

You will also need to treat your whole entire lawn, large turfs, and other landscaped areas. When using granule, you will need to irrigate the treated area to activate the granule.

For indoor treatment, the silverfish can hide in cracks and crevices so you will need to use dust (DELTA DUST), liquid spray (FenvaStar EcoCap), aerosol ( ALPINE AEROSOL), and stations (DEKKO SILVERFISH PACKS).

Apply the dust (DELTA DUST,) using the duster (BELLOW BULB DUSTER) into cracks and crevices of your home. Apply it uniformly and DO NOT OVER USE DUST. Do not apply dust where children and pets can touch.

Following the instructed amounts for liquid spray (FenvaStar EcoCap) on the label, spray around window/door frames, in basements, in baseboards, closets, and any place where there is silverfish activity using a hand sprayer .

Using aerosol ( ALPINE AEROSOL), spray around window/door frames, in kitchens, and on walls. Since the silverfish comes into homes through cracks and crevices, it might live in the voids in the walls, if that the case, you will need to make an access (i.e. drill a hole into the wall and/or removing the electric outlet cover) and apply dust (DELTA DUST) using a duster (BELLOW BULB DUSTER,) into the hole, however not directly because the dust might blow back out, you will need to spray the inside around the hole.

For aerosol treatment in a void, you will need to attach a thin straw to the aerosol and spray it into the access. When using aerosol ( ALPINE AEROSOL), be cautious around electric objects because aerosols are a liquid spray. You can also apply aerosol onto shelves, but first remove everything on the shelves before application.

Do not replace objects back to the shelves until the aerosol has dried completely. Clean the shelves thoroughly before replacing objects onto the shelves. You can use the station (DEKKO SILVERFISH PACKS) and place 2-3 of them in closets, drawers, bookcases, in basements, and any where else that silverfishes inhabit. You will need to replace them every 3-4 months from the date of purchase.

    You have listed 4 items, delta dust, liquid spray, an aerosol, and the stations. Are all four required, or can the duster and spray with stations be effective if used together without aerosol?
    I am planning to use aerosol (the kind you set off and leave for 2 hours) in attic area and maybe upstairs living area, but can the aerosol type be used in the kitchen if all dishes & surfaces are then washed? We have tried the spray alone with little success.

    Hello Joanne,

    Basically, the aerosol would be for instant contact kill when you see them on the spot.
    You would be able to use the fogger (kind you set off and leave for 3 hours).
    There are specific instructions that come along with using the fogger.
    If you are going to use it in the kitchen, you would have to unplug your refrigerator,
    cover your dishes, and remove all exposed foods.

    Also, for basic fogging treatments, you would have to vaccum thoroughly
    and turn off all ignition sources, such as, pilot lights, electrical appliances, etc.
    You would fog the room for one hour, and let it ventilate for two hours.

    After everything has dried, we recommend going in the the dust.
    If you have any other questions, feel free to post again!

    We have silverfish in our attic and walls due to not enough attic ventilation which has also caused black mold. We see a dozen or less in the house every week. We have to take care of the black mold and add roof ventilation but how much or these products do I need as I’m not seeing them gather in one particular spot in the house. They are randomly migrating from the attic.

    Hi Karen Foxx-Smith,

    We recommend the Dekko Silverfish Paks for silverfish and they require no mixing of chemicals or manual application. We do suggest that the black mold is taken care of as soon as possible as it can be potentially very dangerous to be around black mold for an extended period of time. We recommend hiring a professional who will be able to take care of the mold without causing the spores to spread out.
