What Are Silverfish?

Silverfish are small, wingless insects known for their fish-like movement and destructive feeding habits. While they are harmless to humans, they can cause a lot of damage to books, wallpaper, and household items. Understanding what silverfish are, how they live, and how to get rid of silverfish is essential for keeping your home pest-free.

First, The Basics

Silverfish (Lepisma saccharina) are nocturnal insects that thrive in humid environments. These nuisance pests are commonly found in basements, attics, bathrooms, and kitchens, where they seek out food sources like carbohydrates and protein. They have a distinctive silver colour, an oval-shaped body, two antennae, and a fish-like wiggle when they move.

Silverfish infestations often go unnoticed until damage is done. They shed their skin as they grow, leaving behind yellow stains and faeces on household items. Since silverfish can survive long periods without food, they can persist in hidden areas for extended periods.

Silverfish Life Cycle

The life cycle of a silverfish consists of three stages: egg, immature silverfish, and adult silverfish. Female silverfish lay eggs in cracks and crevices, which hatch in about two to eight weeks. Immature silverfish resemble adults but are smaller and undergo multiple moults before reaching maturity.

Silverfish are also known for their longevity, often living several years. Their ability to survive without food and high moisture requirements make them a challenging pest to eliminate.

Where Silverfish Are Found in Your Home

Silverfish in your home are most likely to be found in areas with high humidity. They prefer dark, damp spaces such as:

• Basements and crawl spaces – Silverfish feed on dust and debris, as well as starchy materials like cardboard boxes.

   

• Bathrooms and kitchens – These pests are attracted to water sources and can be found near tubs, sinks, and shampoo bottles.

   

• Closets and bookshelves – Silverfish infest books and magazines, as well as linen, carpet, and wallpaper.

   

The Damage Silverfish Cause

While silverfish are harmless to humans, they can be a significant nuisance in homes. Their destructive feeding habits target household items such as:

• Books and magazines

   

• Wallpaper and glue

   

• Starchy foods like dry foods and cereals

   

• Cardboard and fabric

   

Silverfish infestations can also trigger allergies in some individuals due to their shed skin and faeces. If left unchecked, they may be found contaminating stored food items and causing structural damage to paper-based materials.

How to Get Rid of Silverfish

Eliminating a silverfish infestation requires a combination of pest control methods. Here are the best ways to get rid of silverfish:

Reduce Humidity

Since silverfish thrive in high humidity, lowering moisture levels can help prevent infestations. Use a dehumidifier in damp areas like basements, attics, and crawl spaces. Proper ventilation and sealing cracks in walls and floors can also reduce humidity levels.

Remove Food Sources

Silverfish feed on carbohydrates and protein found in household items. Store dry foods in airtight containers, clean and dry spills immediately, and keep food storage areas free from dust and debris. Vacuum regularly to remove food sources like dead insects and pet hair.

Use Natural and Chemical Treatments

• Diatomaceous earth – This natural insecticide dehydrates silverfish upon contact.

   

• Boric acid – A proven method for extermination, boric acid can be applied in cracks, baseboards, and around bookshelves.

   

• Cedar and airtight containers – Cedar blocks in closets and storage areas can repel silverfish.

   

Hire a Professional Pest Control Service

If a silverfish infestation persists, hiring a professional pest control expert is the best way to get rid of silverfish. Pest control professionals use targeted treatments, including residual insecticides and preventative measures, to eliminate silverfish and prevent future infestations.

Prevent Future Silverfish Infestations

To prevent future infestations, homeowners should take proactive steps such as:

• Sealing cracks and small openings where silverfish hide

   

• Reducing clutter, especially cardboard and paper storage

   

• Using preventative measures like cedar and diatomaceous earth in vulnerable areas

   

• Keeping linen, carpet, and wallpaper clean and dry
