Seeing one silverfish does not always mean a full infestation. But frequent sightings, shed skins, or tiny holes in paper or fabric can indicate a hidden population living nearby.
The most important step in controlling them is reducing moisture. Fixing leaks, improving ventilation, and using dehumidifiers makes the environment less suitable for them and helps stop them from returning.
In the end, silverfish are more of a warning sign than a threat. If the humidity and hiding places are removed, they usually disappear on their own, leaving the home cleaner, drier, and under control.
