Living in dark moist places leaving their droppings everywhere

Silverfish (Latin name Lepisma saccharina) is an insect that can grow up to 12-20 mm in length. They have teardrop shaped body which colour varies from white to brown-grey or bluish-silver. They look like fish and have similar movements like fishes. Silverfish have two long antennas on top of their head and three long bristles on their rear. While growing from an egg stage to adult, they do not have any visible changes in their appearance.

These insects are capable to live in most climates, but they prefer dark and moist places, with moderate temperature areas, such as attics, basements, laundry rooms, kitchen and bathrooms. Silverfish can be commonly found under sinks, bathtubs, bookcases, on closets, in wall voids, door and window frames. They can be often found in stored box full of clothes and papers in garages and storerooms.

Silverfish eat mould, fungi, carbohydrates (starch, cellulose and sugar), glue in books, shampoos, soaps, silk, linen, plants and dead insects. Sometimes they can get into unopened food packages.

Silverfish pest control

There are two ways of silverfish pest control – natural and chemical.

They both can be useful, but chemical way is much more expensive and harmful. By choosing natural pest control, you will get a much safer treatment that won’t do any harm to you, your children and pets. You have a wide range of solutions and traps for this kind of insects that can be bought at stores or made at home.

Natural silverfish pest control

By using a natural method, first step is to find all places of infestation which are typically near the source of their food. After you find these places, next step is to select the product that best fits your needs. There are many available solutions like citrus spray, spices, mothballs, diatomaceous earth, lavender oil, cucumber, cedar shaving.

  1. Citrus sprays – they smell like citrus and are made to eliminate bugs like silverfish because they don’t like citrus smell. It has to be sprayed in all places that have been infested.
  2. Spices – silverfish don’t like spices like bay leaves, whole cloves and sage because of their strong scent. Place these spices in thin sachet near places of infestation. It will turn them away from coming back to that place.
  3. Mothballs – insects like silverfish can’t stand their smell. Good way is to place them where insects are seen often.
  4. Diatomaceous earth – it causes dehydration on bugs that ends with their death. It comes as a white powder and is lethal to pests and not for people and their pets. By dusting areas where silverfish can hide, they will die just from walking through powder. Diatomaceous earth is useful as long as it is dry.
  5. Lavender oil – bugs will stay away from it because of its scent. Mixing a teaspoon of concentrated lavender oil with some water, and by placing it on areas where silverfish have been seen, you will clear them from your home. Spray that mixture on the walls, carpet, cupboard doors, on furniture and other places where bugs can be found. Allow that surfaces to dry and repeat that procedure from time to time.
  6. Cucumber – silverfish also don’t like cucumber smell. Put thick slices of cucumber in places where they might appear. Change the dried slices with fresh ones.
  7. Cedar shavings – it can be used for getting rid of silverfish in the shape of cedar shavings or pieces.

Chemical silverfish pest control

If you choose to use chemical products to get rid of this pest, you have to know that you will pay much more by buying silverfish pest control products or hiring professional services for extermination. You also have to be aware that neither way will guarantee success.

Liquid pyrethrin is most used chemical product for silverfish extermination. By spraying it on the cracks of furniture, doors and windows you will kill adult silverfish but you won’t harm their eggs.

Boric acid is the other solution for killing silverfish. It is powder and is used in small amounts on infested areas. If it gets moist, just use it again.

Baits and traps

There are many traps on the market that can be used for silverfish extermination and they can be cheap and safe to use. One of them is moist and rolled up newspapers. You tie them with elastics and leave them overnight to catch these bugs. Next day they might be full of silverfish and you just throw it in garbage outside the house. Repeat this method every night until you rid them all.

Take the glass jar and mask it with a tape. You can fill it with bread or with water and few teaspoons of sugar as bait. Place that jar near infested places. Silverfish will climb up the tape and will fall in the jar. They will die in jar because they are not able to climb up the slick sides of the jar.

Sticky traps are also effective and you can buy them in any local hardware store. These traps attract bugs which then get stuck in glue. For silverfish baits you can use moist cotton and starchy food items.
