- Sightings at night
- Small holes in paper products
- Damaged book pages
- Yellow stains on fabrics
- Tiny pepper-like droppings
- Shed skins near hiding places
Because silverfish molt throughout their lives, discarded exoskeletons are often found near active populations.
A Non-Toxic Plan to Get Rid of Silverfish
The most effective silverfish control strategy focuses on removing the conditions they need to survive rather than relying solely on chemical treatments.
Step 1: Reduce Humidity
Since silverfish depend heavily on moisture, lowering indoor humidity can dramatically reduce their numbers.
Consider:
- Running a dehumidifier
- Improving ventilation
- Repairing leaks promptly
- Using exhaust fans
- Fixing condensation issues
Aim to keep indoor humidity below 50% whenever possible.
Step 2: Eliminate Food Sources
Reduce access to materials silverfish enjoy.
Store:
- Flour
- Rice
- Pasta
- Pet food
- Cereal
in sealed containers.
Also remove:
- Excess cardboard
- Old newspapers
- Unnecessary paper clutter
