Key Takeaways
- Silverfish live 2–8 years and can survive months without food.
- Females lay up to 100 eggs in dark, humid areas.
- Reduce moisture to prevent infestations effectively.
- Signs include yellow stains, small holes, and shed skins.
- Control silverfish by reducing humidity, sealing cracks, and regular cleaning.
- They require water to survive, so fix leaks and dehumidify your home.
How Long Do Silverfish Live?
Silverfish have a remarkably long lifespan for such small insects, living between 2 to 8 years, depending on environmental conditions. One reason for their longevity is their ability to adapt to various environments. While they prefer humid areas, they can survive in a range of climates. Silverfish exhibit slow development, taking up to 3 years to fully mature. This slow growth allows them to remain in a juvenile stage for extended periods, contributing to their long life cycle.How Long Do Silverfish Live Without Food?
Silverfish are resilient pests capable of surviving for several months without food. However, their survival rate decreases in dry conditions since they rely on humidity for hydration. In optimal conditions, silverfish can continue to live and reproduce, making them challenging to eradicate.How Do Silverfish Reproduce?
Silverfish reproduction is a slow but steady process. Mating involves a unique dance-like ritual, where the male and female perform movements before transferring sperm. Once fertilized, female silverfish can lay between 2 to 20 eggs at a time and up to 100 eggs over their lifetime. The eggs are laid in dark, humid areas such as cracks, crevices, and hidden spaces. Depending on the environment, the eggs hatch in 3 weeks to 2 months, with warmer, more humid conditions accelerating the process.

Silverfish go through three stages: egg, nymph, and adult. After hatching, nymphs resemble miniature versions of adults but are white in color. They grow by molting, shedding their outer skin up to 60 times throughout their lives. Each molt allows them to grow into their signature silvery-blue adult form, enabling their long lifespan.Where Do Silverfish Lay Their Eggs?
Silverfish lay eggs in dark, damp, and secluded areas such as cracks in walls, under floorboards, and inside books. The eggs are tiny, less than 1 millimeter, making them hard to spot without close inspection. Identifying and treating these egg-laying sites is crucial for preventing infestations.Common Signs of Silverfish Infestation
-
Yellow stains on books, papers, or other materials.
-
Tiny holes in wallpaper, clothing, or upholstery.
-
Shed skins from molting silverfish.
-
Faecal pellets resembling small black pepper grains.
Effective Methods to Control Silverfish
-
Reduce Humidity: Use a dehumidifier or improve ventilation to create less hospitable conditions for silverfish.
-
Seal Cracks and Crevices: Prevent silverfish from accessing hiding spots by sealing entry points in walls and floors.
-
Regular Cleaning: Eliminate organic debris such as dust, paper, and food particles to remove food sources.
-
Use Insecticides: Apply insecticides designed specifically for silverfish in targeted areas.
-
Set Traps: Sticky traps or natural deterrents like diatomaceous earth can help catch silverfish effectively.
