    FAQs: Silverfish Killer Powders

    How do silverfish powders work?

    They kill by damaging the insect’s outer shell, causing dehydration. This physical method is effective and chemical-free.

    Where should I apply the powder?

    Apply in dark, damp areas like skirting boards, behind sinks, in cupboards, or along cracks and corners where silverfish may hide.

    Is the powder safe for use in homes with pets and children?

    Yes, non-toxic powders like food-grade diatomaceous earth are safe when used as directed. Keep the area undisturbed and dry for best results.

    How often should I reapply?

    Reapply every few weeks, after cleaning, or when silverfish activity is noticed again.

    Very effective

    I’ve had a persistent mouse problem since moving house last year. I tried a few different solutions, including an electric trap, but they didn’t work. These baited with a bit of peanut butter work cleanly. Worth spending the money on something that does the job it’s supposed to do.
