How to Quarantine Antique Furniture for Pests

Quarantine prevents insects from moving from a new or suspect object into a collection. Old flight holes do not prove current activity, so monitoring matters.

Why the material is vulnerable

Furniture can harbour wood-boring beetles, clothes moths, carpet beetles and other pests in timber, upholstery and debris.

What to inspect

Look for fresh frass beneath holes.
Inspect upholstery, felt and hair stuffing.
Check cracks, drawers and packaging.
Use appropriate traps around isolation area.
Record dates and findings.

Photograph condition and identify every material before cleaning. Check hidden and protected areas; damage often begins at edges, fixings and interfaces between unlike materials.

Safe care

Place the object in a clean, dry, inspectable isolation space away from other collections. Use a light-coloured floor barrier to reveal debris. Treatment such as freezing or controlled heat must suit all materials.

Start with environmental correction and the least interventive method. Use clean barriers, soft tools and controlled suction only where the surface is stable. Stop if colour, flakes, fibres or corrosion products move.

Avoid

Spraying household insecticide.
Sealing a damp object in plastic.
Assuming cedar repels an infestation.
Treating old holes without evidence.
Bringing packaging into clean storage.

Monitoring and specialist help

Inspect at defined intervals and identify the pest before treatment. Active infestation in mixed materials needs integrated pest management.

Seek a conservator for active flaking, mould, structural failure, rare materials, protected wildlife products or uncertain earlier treatments.
