Silverfish like damp conditions, so are often found in kitchens and bathrooms. They can walk up surfaces that are rough, such as wallpaper, but are unable to walk up smooth surfaces such as glass. Because of this they can often be found trapped in baths and basins.
Silverfish are nocturnal and dislike the light. During the day they hide in cracks, behind wallpaper, and under floor coverings.
A female silverfish can lay up to 100 eggs, usually in cracks and under objects. These are white and smooth at first, but them become brown and wrinkled. The young silverfish are white in colour, but at three months grow scales and turn silver. A typical silverfish can live up to 3 ½ years.
