The most effective way to control silverfish is to eliminate the damp environments they thrive in. Use dehumidifiers, add and use ventilation fans, rearrange storage areas so there is air flow between boxes, repair leaks and seal walls and floors.
Silverfish are nuisance pests that generally do not cause damage and do not spread diseases, so experts suggest tolerating them in small numbers. Due to their small size and nocturnal habits, it can be difficult to find where a silverfish infestation is concentrating, so lay out sticky traps all over the building to find the most efficient locations for pest management. In extreme cases, use boric acid to kill large infestations while fixing environmental conditions.
