Silverfish, though bearing a creepy appearance, are relatively harmless pests to humans. They generally will feed on books, clothing, cereal products and other starchy materials found near moist environments. Silverfish infestation can be determined through damage to these materials and presence of pepper-like feces around the affected areas.

Silverfish are nocturnal insects so seeing them during the day is a rare occurrence. The most noticeable sign that silverfish are present in the arrival of skin casts in a bathroom or basement area. These pests can also leave small holes in clothing, wallpaper, cardboard materials and fabrics. You may also find yellow stains on these materials.

Removal Methods

Because the silverfish is a crawling, wingless insect, using powders and sprays are the most effective prevention or treatment option due to their movement habits. There are several proven chemical and natural substances that are effective in preventing and removing silverfish.

Diatomaceous Earth

Diatomaceous earth is a food-grade powdered substance that is effective in killing most any crawling insects. The powder is formed through grinding fossilized materials to create a sharp dust that punctures the exoskeletons of crawling insects to induce death. Leaving this powder in suspected travel routes will kill all crawling bugs naturally. Diatomaceous earth is a preferred treatment because it is harmless to pets and people.

Boric Acid

Boric acid is a natural toxic chemical that is beneficial in killing many insects, including silverfish and their eggs. Sprinkling boric acid along baseboards and underneath bathtubs can efficiently kill silverfish. Be careful not to inhale this powder, as it is toxic to the lung.


Pyrethrin is a chemical derived from the Chrysanthemum plant that targets the nervous system of insects. This chemical should not be placed in areas where food sources and kitchen cabinets are located to avoid contamination due to its toxic nature. It is important to keep pets and children away from treated areas.
