Wood Borers in Wooden Sofa Frames

The fabric or leather you see on a sofa hides a wooden frame, and that frame can be attacked by wood borers without any visible sign from the top. The first hint is often a wobble, a creak or a little powder on the floor under the sofa.

This guide explains the signs, the risks and the approach to treatment.

The short answer

Wood borers can infest the wooden frames of sofas, especially exposed legs, rails and the hidden frame beneath the upholstery. Signs include tiny round holes in legs and visible frame parts, fine powder on the floor, creaking, wobbling, sagging and weak joints. Because the frame is covered, damage is often found late. Treatment typically focuses on accessible wood, using products suited to indoor furniture, and may require removing the dust cover on the underside, with a professional deciding how far to go. Severely damaged frames may need repair or replacement. Isolate the sofa from other wooden furniture meanwhile.

Where borers affect sofas

• Exposed wooden legs, feet and arm supports.
• Frame rails and cross members under the seat and back.
• Hidden joints and corner blocks.
• Wooden sections of recliners and sofa-cum-beds.

Signs

1. Tiny round exit holes in legs and visible wood.
2. Fine powder on the floor beneath.
3. Creaking, wobbling or sagging.
4. Soft or hollow wood on the underside, when the dust cover is lifted.
5. Looseness at joints.

Checking

• Tip the sofa carefully, or lift the dust cover and look with a torch.
• Probe exposed wood with a screwdriver tip.
• Check legs for holes and soft spots.
• Look for powder on the floor and ledges.

What to do

1. Photograph signs and mark the affected areas.
2. Keep the sofa away from other wooden furniture.
3. Do not spray insecticide on the upholstery.
4. Call a professional for identification and a plan. They may treat accessible wood through injection and surface treatment and discuss options for hidden frames.
5. Keep children and pets away during treatment and until the area is aired.
6. Have a carpenter or upholsterer repair or replace weakened frame parts.

Safety

A weakened frame can collapse suddenly. Do not use a sofa that is wobbling or visibly damaged until it has been checked.

Prevention

• Keep sofas away from damp walls and leaks.
• Check the underside and legs every few months.
• Seal exposed wood.
• Check second-hand sofas for holes and powder.
• Ask for treated frames when buying new.

Other pests

If you see mud tubes, check for termites. If there are bites, consider bed bugs and other pests. A professional can sort them out.

When to call a professional

If you find holes, powder or a failing frame, call a professional before the damage worsens.
