Silverfish in the house: If you want to fight them, you should pay attention to moisture. Humidity can be reduced by ventilation and heating in damp rooms.
Extremely damp areas (e.g. due to water damage) should be structurally removed as quickly as possible. A piece of newspaper with honey or a sliced potato makes the bait. This goes into an open plastic bag that is placed in a dark place. The animals would then collect in the bag overnight and could simply be disposed of outdoors.
