Silverfish eggs have a lifespan of two to three years, but the exact length depends on the environment. They are usually laid in small crevices and cracks.
When a female silverfish lays eggs, she typically lays a cluster of 2-20 eggs. The male releases sperm that fertilizes the female’s eggs. These eggs develop into nymphs, smaller versions of the adult.
After they mature, the nymph continues to molt. Some species may molt up to 50 times. This is important for preventing water loss from the insect’s body.
Silverfish usually live in dark, damp areas. However, they can also be found in attics, bathrooms, and closets. In these areas, the moisture levels and humidity are perfect conditions for silverfish development.
Silverfish nymphs are paler in color than adults, but they still continue to molt throughout their lifetimes. Their waxy coating helps prevent them from losing water.
Female silverfish lay eggs any time of the year. They usually lay one to three eggs a day. A female can produce up to 100 eggs in her lifetime.
It is difficult to see silverfish eggs, so you should be careful. Most are elliptical in shape and are less than a millimeter in length. You can use a magnifying glass to help identify them.
Female silverfish lay eggs in hard-to-reach places. Usually, they are buried in dust or food. If you think you have an infestation, you can use a vacuum to remove them. Alternatively, you can use diatomaceous earth.
