Silverfish Facts and Information

Despite their name, silverfish are not related to fish at all. In fact, they are tiny insects known for their fish-like appearance and quick movements. Although they are generally not harmful to humans, they can become a nuisance in homes and cause damage to belongings. If you have a silverfish infestation, it’s important to take action. 

Silverfish are one of the oldest insect species in the world, with fossils dating back to the Devonian period of the Paleozoic Era, which means they have been around for almost 400 million years. Adult silverfish can grow up to ¾ inches in length and are characterized by their shiny, silver-colored body, which is covered in fine fish-like scales. They also have two front antennae and three bristle-like appendages on their rear end. 

While silverfish are not dangerous to humans, they can cause damage to books, paper products, and fabrics, as they feed on the starches and sugars found in these materials. Additionally, they can trigger allergies in some people. Therefore, if you notice an infestation of silverfish in your home, it is important to take steps to eliminate them before they cause further damage.
