Introduction to Silverfish
Silverfish are among the most common household pests in Malaysia, yet many homeowners are unaware of their presence until it's too late.
These tiny, wingless insects are known for their destructive habits, particularly in humid environments like bathrooms, kitchens, and storerooms.
In this guide, we will explore everything about silverfish: what they are, how to identify them, and how to eliminate them effectively. If you're dealing with mysterious damage to books, clothes, or wallpaper, a silverfish infestation might be the culprit.
What Are Silverfish? Characteristics & Appearance
Silverfish, known as "gegat" in Malay, are small, silvery-grey insects with a fish-like appearance and tapered bodies. They typically measure around 12-19mm and move in a wriggling motion.
Key features:
Wingless but fast-moving
Covered in silver or grey scales
Long antennae and bristle-like tails
Despite their name, silverfish are not fish. They're insects that have been around for over 400 million years.
Where Do Silverfish Come From?
Silverfish thrive in dark, moist environments. Common entry points include:
Cracks in walls or floors
Cardboard boxes and old books
Drains and under sinks
Once inside, they reproduce quickly. Silverfish eggs are tiny and hard to detect, often hidden in baseboards or under flooring.
Are Silverfish Harmful to Humans or Property?
While silverfish do not bite or transmit diseases, they can be extremely destructive to belongings. They feed on starchy materials and proteins found in:
Paper (books, magazines)
Fabrics (cotton, silk)
Glue and wallpaper paste
This can lead to costly damage if left untreated.
Signs of a Silverfish Infestation
Identifying a silverfish infestation early is key. Look out for:
Shed silverfish skins
Yellow stains on paper or fabric
Irregular holes in books or wallpaper
Spotting the insect itself at night
Silverfish are nocturnal, so infestations often go unnoticed until significant damage is done.
How to Get Rid of Silverfish: Prevention & Treatment
Here are some ways to keep your home silverfish-free:
Prevention Tips:
Keep humidity levels low
Store books and clothes in airtight containers
Seal cracks and crevices
DIY Treatment:
Use silverfish traps
Sprinkle diatomaceous earth or boric acid
Place mothballs in affected areas
However, for serious infestations, professional pest control is recommended.
