Home Remedies for Silverfish: What Works and What Doesn't

Many remedies are suggested for silverfish. A few help, many do not.

The short answer

Reducing humidity, removing food sources and sealing cracks work best. Traps made with sticky paper can catch some. Cedar, lavender or cloves may have mild effects but fade quickly. Diatomaceous earth can kill some but needs care. Mothballs and naphthalene are not recommended due to health risks. Use remedies as an addition, not a replacement for fixing damp.
