Silverfish are nocturnal insects that live in damp, moist areas. They are omnivorous and prefer protein, carbohydrates, and starchy foods. Some species may also eat glue, dead insects, and fabric.
Silverfish reproduce quickly. Female silverfish lay eggs singly or in groups of up to 20. The eggs are oval in shape, and can hatch in up to three weeks.
When they first hatch, they are about one millimeter in size. As the young silverfish grow, they change to a whitish color and develop a metallic shine. By the time they reach adulthood, they are about a quarter of an inch in length.
Silverfish molt frequently, and their bodies shed their skin. Unlike other bugs, the process doesn’t result in metamorphosis.
To mate, the male and female silverfish engage in a complex ritual. During the ritual, the male and female silverfish perform love dances. This involves the male vibrating his tail against the female’s antennae. After they touch, the male releases a spermatophore, which fertilizes the female’s eggs.
Eggs are usually laid in dark, moist areas. These areas are usually in crevices and cracks. Depending on the species, some eggs may hatch in as little as two weeks.
A silverfish’s life cycle lasts about two to eight years. They are generally nocturnal, and their main activities are nighttime. Most silverfish live in moist places, such as basements and attics, where they can withstand long periods of drought.
Silverfish are mainly active at night, so if you find them in your home at daytime, it’s probably because they’re searching for food. The best way to avoid an infestation is to keep food in tight containers and keep water sources dry. If you can’t do that, dehumidifiers and air conditioning systems can help.
