What Are Silverfish?
Silverfish are small insects that live in homes. They have a silver color and a fish-like shape. That is why they are called “silverfish.” They like dark, damp places. You may find them in bathrooms, kitchens, and basements. They come out at night to look for food.
What Do Silverfish Eat?
Silverfish eat many things. Their favorite foods are starch and sugar. They like to eat paper, glue, and fabrics. They also eat dead skin and crumbs. Silverfish can damage books, wallpaper, and clothes. They chew on these materials because they have starch in them.
Do Silverfish Eat Money?
Now, the main question: do silverfish eat money? The answer is yes, but only in some cases. Silverfish do not eat money like food. They do not want to eat coins or metal. But paper money can be a target for silverfish.
Why? Because paper money contains fibers. These fibers come from plants like cotton and linen. Silverfish like to eat these fibers. Also, paper money often has glue and starch in it. Silverfish eat glue and starch too. So, if silverfish find paper money, they might chew on it.
This is true mostly for old or dirty paper money. New, clean money is less likely to be eaten. The chemicals and plastic coating on some new bills can stop silverfish.
How Do Silverfish Damage Paper Money?
Silverfish use their jaws to chew paper. They make small holes and rough edges. If silverfish live in your home, they may damage money stored in old boxes or drawers. Money left in dark, damp places is at higher risk.
Silverfish do not eat money to get nutrients like humans. They eat it to get starch and fibers. Their chewing can make money hard to use or read. This can be a problem if you keep cash at home.
Signs Of Silverfish Damage On Money
- Small holes on the paper bills.
- Edges that look chewed or rough.

If money is stored in these places, silverfish may find it.
