Silverfish in a New Flat: Why Fresh Paint and Plaster Attract Them

New flats can have silverfish because construction leaves moisture and glue-rich materials.

The short answer

New plaster, paint, wood adhesives and cartons all hold moisture and starches. Ventilate well, run dehumidifiers if needed, clear cardboard and packing materials, seal cracks and avoid leaving books or clothes on bare floors. Moisture usually falls over time. Persistent infestations may need professional help.

Why new flats

• Residual moisture in plaster and screed.
• Starch-based glues and cardboard packaging.
• Gaps and cracks.

What to do

1. Ventilate and dehumidify.
2. Remove cardboard and packing.
3. Seal cracks.
4. Keep stored items off the floor.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
