Silverfish are pests that can cause serious damage to your home. They live in dark, damp areas and are attracted to moisture. If you suspect you have a silverfish infestation, the first step is to eliminate their food sources.
The best way to do this is by storing your foods in a sealed container. Also, you can use a dehumidifier to reduce the moisture in the air.
You can also use a sticky trap. One is fairly simple: take some roll up newspaper, tape it together with elastic bands and bury it in your home. It will serve as a trap and catch the silverfish.
Another way is to make a paste from flour and water. Place it where the silverfish are likely to travel. Leave it there for a few nights. Use a mask if you plan to spray it around the house.
Essential oils are another great repellent. Depending on the concentration of the essential oil, you can sprinkle it on your counter top, dresser or even your bedroom. These oils are not only effective, they are non-toxic to humans.
Boric acid is a natural substance that will kill silverfish. However, it can present a health risk to pets and children. Unless you are a professional insect killer, you should avoid using it in areas where pets and children might be exposed to it.
Citrus fruit peels can be used as a silverfish repellent. They are a good source of citric acid and they can be placed in infested areas. Just be sure to change them regularly.
