- Excess humidity
- Water leaks behind walls or under sinks
- Poor ventilation
- Damp cardboard, books, or paper products
- Accumulated clutter that provides hiding spots
Silverfish feed on starches, adhesives, paper, fabric fibers, and even dead skin cells. As a result, they are often found near old books, wallpaper, storage boxes, and closets.
Are They Dangerous?
The good news is that silverfish do not bite humans, sting, or spread diseases in the way some other pests can. However, large infestations can become a nuisance.
Over time, they may damage:
- Books and magazines
- Important documents
- Wallpaper
- Clothing made from natural fibers
- Stored food products
Their presence may also signal moisture problems that could eventually contribute to mold growth or structural issues if left unaddressed.
