Signs You May Have an Silverfish Infestation
Silverfish are nocturnal and hide well, so signs matter. Common signs include:
-
Seeing small silver/gray insects dart away quickly
-
Silverfish near sinks, tubs, or bathroom floors
-
Tiny yellowish stains or shed skins in corners
-
Small holes or damage in paper, cardboard, or fabric
-
Activity getting worse in humid months
Where Silverfish Hide Around Homes and Businesses
Silverfish prefer dark, damp, undisturbed areas like:
-
Bathrooms and under sinks
-
Basements and crawl spaces
-
Laundry rooms and utility closets
-
Behind baseboards, trim, and wall voids
-
Storage boxes, bookshelves, and pantry areas
Why Silverfish Keep Coming Back
Silverfish thrive in moisture and feed on paper, glue, and starchy materials. If humidity stays high, silverfish continue hiding and spreading through storage areas and hidden voids.
