Silverfish Appearance

They have oval-shaped, flat, soft bodies covered in shiny silver scales, giving them their names. Adults can grow up to ¾ of an inch long and have two antennae on their heads and three tail projections.

Adult female Silverfish lay eggs regularly, almost daily, and considering these pests can live for a span between 2 to 8 years, that’s a lot of eggs. Young Silverfish look just like adult silverfish, just smaller and more white than silver.

Having an infestation of Silverfish can be hard to treat, and you may need to call in a pest specialist. Since this pest has such a long life span, it lays eggs regularly and goes for a long time without food, sometimes up to a year. Making getting rid of them that much harder.

Where do they live?

Silverfishes are the kind of pests that like to live in dark, damp areas in your home. They will hide during the day to avoid sunlight, same as rats and mice.

If you move an object that they are hiding under, you will see them dart away, looking for a new place to hide. It’s common to find large populations of silverfish living and thriving in new buildings with wet stone and brick even without noticing any entry points.

Having the nest removed is something that our professional pest control in London includes as part of the pest control treatment.

Are they harmful to humans?

Silverfish are generally a nuisance. They don’t bite people, but they will leave droppings in your food, and their droppings can leave stains behind if not cleaned properly.

Some people are allergic to the droppings or molted skin left behind from Silverfish.

Silverfish are more of a threat to your home and cause a lot of damage as they eat away at your belongings.

Glue – Silverfish eat glue and will eat the glue holding your wallpaper in place. As well as glue in book bindings, carpet, curtains, and furniture.

Paper – With a taste for starchy materials, you will find Silverfish munching away at your books and magazines, especially if they have a starchy coating like a smooth, glossy finish.

Linens – Any starched linens in your home are at risk of being eaten by Silverfish. You may find them eating your curtains, furniture coverings, and anything made from cotton or silk.

What do they eat?

How to get rid of Silverfish


This pest can be as common as cockroaches in some areas. An infestation can be challenging to treat and should be handled by a pest control specialist.

There are some things you can do around your home to help manage the infestation.

  • Store your food in thick plastic or glass containers, and always clean up food when done, including wiping up spills and crumbs.
  • Vacuum your home regularly. Be sure to focus on areas where food is eaten, and all the crumbs are vacuumed up. The area of carpet you have under your furniture should also be vacuumed regularly.
  • Use a dehumidifier. Silverfish love humidity and water. Repair any leaks and use a humidifier if there is dampness in the air; that’s very common for a basement. Make sure the landscaping of your home allows for water to run away from your home and keep windowsills and caulking in cracks in good repair.
  • Silverfish lay eggs in cracks and crevices. Fill in any that you come across to stop them from laying eggs inside.
  • Use dust like diatomaceous earth and boric acid in areas you and your family often don’t frequent, like a crawl space.
  • Use Japanese cedar essential oil in areas that you suspect silverfish to deter them.

Silverfish prevention

Here are some tips for your peace of mind to prevent these pests from coming into your home and damaging your belongings.


  • Dust often. This will help remove any particles that have starch in them from building up and creating a 24 hours a day silverfish buffet.
  • Remove items with adhesive from your home. This includes laundry, cardboard boxes, stacks of paper; of course, this may not be easy, but cutting back on these items in your home is a good deterrent.
  • Store clothes in dry environments. When storing away out-of-season garments, be sure to store them in plastic containers to keep Silverfish out.
  • Use caulking. Fill in any holes, cracks, or crevices in your home to prevent them from laying eggs in them.
  • Ventilate rooms that get hot and humid. Open up windows and allow some airflow in any rooms that get hot and humid to help clear moisture from the air.
  • Get rid of outside debris. Clear up any piles you have in your garden of brush, leaves, wood, or dead plants for a pest-free home.


Silverfish are relatively harmless to humans since they don’t bite and are not known to spread disease. Some people may have an allergic reaction, but most people’s health isn’t affected by these pests being in their homes.

However, having a silverfish infestation is still unpleasant and can cause damage to your possessions. Seeking a pest control solution from the London area is your best bet to exterminate any pests quickly and efficiently.
