Silverfish are small, wingless insects. They are nocturnal, so they usually hide in dark, moist areas. Their bodies are teardrop-shaped. The silverfish is approximately half an inch long and has bristles on its back.
In warmer climates, silverfish can grow up to eight years, while in cooler climates it can take up to two years. They can survive without food for weeks. A female silverfish lays around 50 eggs in an average clutch.
The female lays her eggs in damp, dark places. They can be buried in clothes, paper, dust, or food. It takes 19 to 32 days for the eggs to hatch.
To remove the silverfish, you should clean your house and eliminate potential nesting spots. You should also apply over-the-counter insecticides in areas where silverfish are likely to breed.
If you want to control a small population of silverfish, use sticky traps. These traps consist of a cardboard base and a thin layer of sticky glue. When the silverfish sees the sticky glue, it is enticed to climb inside and get stuck.
The silverfish can also be repelled by citrus fruit extracts. Lemon peels contain limonene, which acts as a natural insect repellent.
In addition, you can use a dehumidifier to dry out a moist area. Another way to prevent silverfish infestation is to keep your house well ventilated.
Often, silverfish can find their way into your home through the foundation or basement cracks. However, they can also enter through the exterior walls and rugs that you have brought into the house from outside.
