How to do it:
Seal cracks and crevices with caulk, reduce humidity using a dehumidifier, store goods in airtight containers, vacuum regularly, and sprinkle diatomaceous earth in affected areas.

Result:

• Blocks entry points for silverfish
• Removes food sources and hiding spots
• Reduces moisture that attracts pests
• Kills silverfish on contact with diatomaceous earth
• Protects stored goods from infestation

Problem:
This method may fail if humidity remains high, cracks are missed, or diatomaceous earth is not reapplied after cleaning, allowing silverfish to return.

How to do it:
Mix equal parts baking soda and powdered sugar. Sprinkle the mixture in areas where you’ve seen silverfish, such as closets, bookshelves, and storage boxes. Replace the mixture every two weeks for continued effectiveness.

Result:
Silverfish are attracted to the sugar but harmed by the baking soda, helping to reduce their numbers naturally and non-toxically.

Problem:
This method may fail if the infestation is severe or if the mixture is not replaced regularly, allowing silverfish to persist.

How to do it:
Physically remove visible silverfish and block their entry points.

Result:

• Inspect storage areas regularly for silverfish.
• Capture and remove any silverfish found using sticky traps or by hand.
• Seal cracks, crevices, and gaps in walls, floors, and around pipes.
• Store goods in airtight containers to limit access.
• Reduce clutter to eliminate hiding spots.

Problem:
This method may fail if hidden eggs hatch or if all entry points are not sealed, allowing silverfish to return.

How to do it:
Use natural predators like house centipedes or release predatory insects such as earwigs in areas where silverfish are seen.

Result:
Predators will hunt and reduce silverfish populations, helping to prevent them from entering your home and damaging goods.

Problem:
This method may fail if predators do not thrive indoors, escape, or if silverfish find inaccessible hiding spots, limiting the effectiveness of biological control.

How to do it:
Mix equal parts boric acid and sugar. Sprinkle the mixture in corners, cracks, and behind furniture where silverfish are seen. Repeat weekly and keep the area dry.

Result:
Silverfish are attracted to the sugar, ingest the boric acid, and die, reducing their population and preventing further damage to goods.

Problem:
This method may fail if the area remains damp, if silverfish find alternative food sources, or if pets/kids access the mixture.
