Silverfish are nocturnal insects that move very quickly. They are very good at darting away from danger and finding a hiding spot out of sight and out of reach. Their ability to avoid threats is their only defense mechanism.
Silverfish feed on carbohydrates. They are particularly fond of starches and sugars and will feed on many different items in your pantry and around your house. It is common for silverfish to ruin clothing, books, and paper products. They will also feed on shampoos and a variety of fibers.
The development of silverfish varies by species and environment. Silverfish eggs can take anywhere from 20 to 60 days to hatch. The more humid the climate, the faster silverfish will hatch and develop into adults. Female silverfish lay their eggs in cracks and crevices, which makes them difficult to find. Their lifespan also depends on the climate. Silverfish can live for about three years in areas with high temperatures and humidity.
Silverfish are covered with slippery protective scales. These scales allow them to slip away from predators. They also allow silverfish to fit in seemingly flat, tight places such as in book spines.
