Silverfish are slender insects, and they usually grow up to one and a half inches long. They are nocturnal, and they prefer damp environments.
These insects live in dark, moist areas, and they are known to be able to hide in corners and under house materials. If you have an infestation of silverfish, you may find their droppings on your kitchen counters or books. Some of these droppings resemble small whole peppercorns.
The adults of these insects have a shiny appearance. Their bodies are silvery gray. They are about 1/4 to an inch long, and they have two antennae on their heads. Despite the fact that they don’t have wings, silverfish are considered fast insects, because they move in a wriggling motion.
As adults, they have a flat, teardrop-shaped body. It is covered with scales. Unlike other insects, they have three tail-like appendages on their abdomens.
Silverfish are nocturnal, and they are most active at night. They have a tendency to run away from light. You can find them in basements, bathrooms, and sub-floors. They are also found in the roof voids of houses.
Silverfish are known to be one of the oldest insects on earth. They are found in 120 species all over the world. Among them, there is one species in the United States, Lepisma saccharina.
Because they are nocturnal, they are rarely seen by humans. Until they have been eaten completely, silverfish can be easily mistaken for other insects. Nevertheless, they are not a dangerous pest.
