If you have ever turned on a bathroom light in the middle of the night and seen a small, metallic-grey insect darting for cover, you have likely encountered silverfish. In Cardiff, where the coastal humidity can keep homes damp, silverfish thrive. If you are wondering how to get rid of silverfish naturally, or when it’s time to call in the experts, this guide is for you.
Why Do I Have Silverfish?
Silverfish are prehistoric insects that haven't changed much in millions of years because they are survival experts. They are attracted to high humidity and starchy food sources. In many Cardiff homes, especially those with stone basements or older plumbing, silverfish find the perfect environment.
They feed on cellulose, which means your wallpaper, book bindings, and even cotton clothing are on the menu. While they don't carry diseases, their presence is often a sign of a larger moisture problem.

How to Get Rid of Silverfish Naturally
If you want to try a DIY approach first, there are several how to get rid of silverfish naturally methods:
- Cedar Oil: Silverfish find the scent of cedar repulsive. Using cedar shavings or oil in cupboards can act as a deterrent.
- Diatomaceous Earth: This natural powder is made of fossilized algae. It is harmless to humans but abrasive to insects, dehydrating them on contact.
- Dehumidification: Since silverfish need 75% humidity to survive, simply running a dehumidifier in your bathroom or basement can stop them from breeding.
Professional Silverfish Control
Natural methods are great for prevention, but if you have a full-scale infestation, they may not be enough to reach the eggs hidden in wall voids. Professional Cardiff pest control involves the use of specialized residual sprays and insecticidal dusts that stay active for months.
When we perform a treatment, we also look for the underlying cause. If silverfish are moving between rooms, they might be using the same entry points as other pests. This is why regular pest inspections are important; catching a damp problem early not only stops silverfish but prevents structural rot.
FAQs
1. Are silverfish harmful to pets?
No, silverfish are not toxic to dogs or cats, and they don't bite. However, the presence of many silverfish could lead your pets to ingest them, which isn't ideal for their digestion.
2. Can silverfish damage my property?
Yes. While they won't knock down a wall, they can destroy valuable documents, rare books, and expensive silk or cotton fabrics. In large numbers, they can also cause wallpaper to peel by eating the starch-based adhesive behind it.
