Because silverfish are nocturnal, they can be hard to find during the day and can only be located from their excrement. This is what they leave behind when they damage books and starchy materials in the house. Isolate dark and damp areas in the house, then you will either find small holes on clothing or yellowish stains on the clothes.

After locating them, you can trap them with a homemade silverfish trap. Find out – are silverfish dangerous?

The homemade trap can be modified by wrapping its outside with a tape (masking) and then placing diatomaceous earth or some pieces of bread in the container. The tape enables a silverfish bug to climb and fall into the jar. The container is then left at some point where you had located them. They will climb the glass and then fall into it in order to eat bread. As they fed more and more will be joining and when you come to check, you will find them inside and kill them. Remember, the inside of the glass will be slippery hence difficulty to escape.

Newspaper traps can also be used to keep silverfish out of your house. The newspapers can be wrapped together and one part tied with a rubber band. Moisten the other end and let the paper trap rest on the areas where you had located them. They will come and feed on the newspapers and since the paper will provide food and shelter, they will eat and sleep there.

The shelter and warmth of you home is what causes them to come inside in the first place.The following day throw the paper out without unfolding them or you can burn them for effective pest control.

Sticky traps

These are already made traps which can be accessed from a hardware store. The traps are made in such a way that they are sticky, a feature important in trapping these creatures. The traps are put at specific points where the organisms hide especially in dark spots, such as kitchen cabinets, and wet areas like laundry rooms. When they start moving around at night, they will come out of their hiding places and make their way onto the trap and they will stick there. Small pieces of starch or bread can be placed on the traps to act as bait. Put some masking tape around the outside to help them climb up. After trapping them, you can kill them with a lot of ease.
