Silverfish Prevention for Sydney Homes

Silverfish are easy to overlook. They are quiet, they hide, and they do their damage slowly in the parts of the home we rarely check. By the time you notice holes in a favourite jumper or grazing on old documents, they have usually been present for a while.

What silverfish are drawn to

These small, silvery, teardrop shaped insects love dark, humid spaces. In a Sydney home that means wardrobes, bookshelves, storage boxes, subfloors and roof voids. They feed on starches and cellulose, which includes paper, cardboard, book bindings, wallpaper paste, natural fabrics and dry pantry goods.

Humidity is the single biggest factor. The damper and stiller the air, the more silverfish thrive, which is why coastal and poorly ventilated homes see them most.

The damage they cause

• Irregular holes and surface grazing on paper and fabric
• Yellowish stains on stored items
• Damage to books, documents, photographs and artwork
• Contaminated dry food in the pantry

How to prevent them

• Reduce humidity with better ventilation, and use dehumidifiers or moisture absorbers in problem areas
• Declutter storage areas, as boxes and stacks of paper are ideal harbourage
• Store important documents and clothing in sealed plastic containers rather than cardboard
• Keep pantry goods in airtight containers
• Address any leaks or damp in subfloors and roof spaces

When to call in a professional

If silverfish keep appearing despite your best efforts, a professional treatment targets their harbourage in roof voids, wardrobes and subfloors directly, and addresses the conditions letting them thrive. It is often combined with a general pest treatment for whole of home protection.

Frequently Asked Questions

Are silverfish harmful to people?

No. They do not bite or spread disease, but they can ruin books, clothing and stored items over time.

Why do I keep finding them in the bathroom?

Bathrooms are humid, which silverfish love. Improving ventilation and reducing moisture makes the space far less inviting.
