How Large Are Silverfish?

Silverfish are tiny critters. They are about half an inch long and silvery. These tiny pests can be found throughout the United States. While they aren’t venomous, they can cause material damage.

Silverfish love moisture, and are typically found in moist environments. This includes areas like the basement, bathroom, or kitchen. Their feeding habits include starchy foods, grains, and decomposing materials.

The female Silverfish lays eggs every few days, usually in cracks or crevices in the home. Once the eggs have been laid, they take about three weeks to hatch. As the silverfish nymph develops, it becomes a darker metallic color.

After several months, the silverfish nymphs moult. During this time, the nymphs go through fourteen stages of development. In the third molt, they develop scales.

Female silverfish are sensitive to moisture. If food is not available, they will survive for a year. To thrive, the adult silverfish must have water, high humidity, and an environment with room temperature.

Unlike most insects, the silverfish will move very quickly. Silverfish are not venomous, but can cause damage to your furniture, books, and other belongings.

The silverfish is a good climber. It can also chew through paper and cardboard. Therefore, it is important to prevent them from entering your home.

The silverfish lays its eggs in dark, moist areas. These eggs are usually found tucked between clothes or other items. The nymphs take about three weeks to grow into adults.

Adult silverfish are about half an inch in length. The males have a spermatophore that releases sperm onto the ground.
