Wood Borers in Wardrobes and Cupboards

Wardrobes are large, often made of timber or plywood, and sit against walls where air does not circulate. The back and base are dark, still and sometimes damp, which makes them attractive to wood borers. Because wardrobes hold clothes and belongings, an infestation raises concerns about contamination and damage.

This guide explains the signs, the protection of contents and treatment.

The short answer

Wood borers in wardrobes show as tiny round holes in panels, legs, frames and the back, fine powder inside or underneath, and hollow or soft wood. Solid wood and plywood and blockboard can all be affected. Borers attack the wood, not clothes, but powder and debris can fall onto belongings. To deal with it, empty the wardrobe, inspect all parts, have a professional treat the wood by injection and surface treatment with products suited to the use, ventilate before refilling, repair damage, and protect the wood from moisture. Keep clothes in sealed covers until treatment is finished.

Why wardrobes are vulnerable

• Large areas of seasoned wood or board.
• Back panels against walls with limited airflow.
• Humidity trapped inside, especially in monsoon.
• Unfinished or thinly finished inner surfaces.
• Second-hand or older wardrobes.

Signs to check

1. Tiny round holes on panels, edges, shelves and legs.
2. Fine powder on shelves, the base or the floor under the wardrobe.
3. Hollow or soft wood, probed gently.
4. Bubbling or flaking polish and laminate.
5. Weak joints or sagging shelves.

What to do

• Empty the wardrobe, and bag or cover clothes. Wash or air items that were near powder.
• Photograph the signs and note the locations.
• Ask a professional to identify the pest, since termites and other pests can look similar, and to treat the wood.
• Treatment usually involves injecting into holes and treating surfaces, including hidden faces. Products suited to cupboards are chosen, and the wardrobe is ventilated before use.
• After treatment, fill holes, repair damaged parts and refinish.

Protecting clothes

• Do not put clothes back until the wardrobe is dry and aired, as advised.
• Wash or air clothes that were near powder or treated surfaces, if advised.
• Use clean liners.

Prevention

• Keep the wardrobe slightly away from damp walls, and leave a gap for air.
• Control humidity with ventilation, and moisture absorbers if needed.
• Seal exposed wood and edges with polish or sealant.
• Check inside and behind every few months.
• Use treated or borer-resistant wood and boards for new wardrobes.

Other pests to check

Silverfish, termites and cockroaches can also use wardrobes. If you find mud tubes, check for termites. See our guides.

When to call a professional

If you see holes and powder, call a professional before the damage spreads to other furniture.
