How Big Can Silverfish Get?

Silverfish are one of the largest nuisance insects in the world. They can be found almost anywhere in a house. The smallest adult is a half-inch long.

These tiny, wingless insects are characterized by their metallic color, fish-like movements, and flattened bodies. Adults can travel quite a distance at night, and can be seen hiding in the nooks and crannies of a home.

Typically, female silverfish lay eggs in a variety of hard to reach places. The nymphs are about two millimeters when they leave their eggs. This process takes about fourteen stages.

Females usually lay about sixty eggs in a lifetime. It can take up to two months for the eggs to develop. Once they do, the nymphs are mature enough to mate.

Adult silverfish can live up to eight years. They are usually nocturnal and can be spotted at night looking for food.

Silverfish are generally shy creatures. They hide in dark, moist areas. Typical breeding grounds for silverfish include shake roofs during the warmer months.

These nocturnal insects are a hazard to both homes and businesses. The best way to prevent an infestation is to vacuum, remove potential food sources, and avoid leaving paper products in the floor.

Although they are a bit elusive, silverfish are not dangerous. If you want to eliminate a silverfish infestation, you can use diatomaceous earth, a natural powder made from fossilized diatoms. Diatomaceous earth is safe for humans and pets, and it can be used as a silverfish repellent.
