Finding a silverfish in your home is usually not a sign of a serious danger, but it can indicate conditions that allow them to thrive.
What silverfish may be telling you
Silverfish are attracted to:
- High humidity or damp areas
- Warm, dark spaces
- Paper, cardboard, books, and wallpaper paste
- Starches found in glue, fabrics, and some foods
Common places to find them include bathrooms, basements, laundry rooms, attics, closets, and kitchens.
What you should do
- Reduce moisture
- Fix leaking pipes or faucets.
- Use a dehumidifier in damp rooms.
- Improve ventilation in bathrooms and basements.
- Eliminate food sources
- Store dry foods in airtight containers.
- Clean up crumbs and spills.
- Reduce clutter, especially stacks of paper or cardboard.
- Seal entry points
- Caulk cracks around baseboards, windows, pipes, and walls.
- Clean regularly
- Vacuum along baseboards, behind furniture, and in closets to remove insects and eggs.
Are silverfish harmful?
Silverfish:
- Do not bite people.
- Do not spread diseases.
- Are not poisonous.
However, they can damage:
- Books
- Wallpaper
- Photographs
- Clothing made from natural fibers
- Stored paper products
When to be concerned
Seeing one silverfish isn’t necessarily a problem. If you’re finding them frequently, it may indicate a larger infestation or excessive indoor moisture. Addressing the moisture source is often the most effective long-term solution, and if the infestation is extensive, a professional pest control service may be helpful.
