Silverfish control
Silverfish control
Understand silverfish activity, moisture causes and practical prevention.
Clear, proportionate guidance—without alarmist claims.
How to recognise the signs
Silverfish are fast, wingless insects associated with humid, sheltered areas such as bathrooms, kitchens, basements and cupboards. Damage may affect paper, wallpaper paste or starchy materials.
What to do now
Record where activity occurs, check for leaks and condensation, improve safe ventilation and inspect stored paper or cardboard in damp areas.
What not to do
Do not rely only on killing visible insects, block necessary ventilation or ignore a persistent moisture problem behind fittings.
Prevention and proofing
Repair leaks, lower sustained humidity, ventilate appropriately, reduce damp cardboard storage and seal suitable cracks after moisture causes are addressed.
What professional help may involve
A professional can confirm identification, inspect hidden harbourages and combine moisture correction, monitoring and targeted control where activity persists.
Before contacting a provider
- Record where and when activity occurs.
- Take clear photographs without disturbing contamination or nests.
- Note previous treatment and access restrictions.
- Ask what inspection, treatment, follow-up and proofing are included.
Frequently asked questions
Do silverfish mean a property is dirty?
No. They are more closely associated with humidity, shelter and suitable materials than ordinary cleanliness.
Will a dehumidifier solve the problem?
Reducing humidity may help, but leaks, hidden voids and established activity may need additional action.
