Repairing Wood Borer Damage: Fillers, Epoxy and When to Replace

Once borers have been treated, the damage is still there. Repair is about restoring strength and appearance, and it must come after, not before, treatment.

The short answer

Only repair wood once a professional confirms the borers are dead. Small holes can be filled with wood filler or wax, while softened or crumbly areas may need consolidation with a wood hardener or epoxy. Badly weakened structural parts, such as legs, rails or frames, are safer replaced. Match the repair to the item's use, strength needs and appearance, and refinish on all faces to protect against new infestation.

Before repairing

1. Confirm treatment is complete and no fresh powder appears.
2. Remove loose, crumbling wood.
3. Clean and dry the area.

Repair options

• Wood filler or wax for small holes and cosmetic fixes.
• Wood hardener or consolidant to firm soft wood.
• Epoxy filler for larger cavities in non-structural areas.
• Splicing or replacing sections for structural parts.

When to replace

• Load-bearing parts such as chair legs and bed rails.
• Doors and frames that no longer hold hinges or locks.
• Wood that crumbles when pressed.
• Parts too hollow to repair safely.

After repair

• Sand and refinish all faces.
• Seal edges and hidden areas.
• Inspect regularly for new activity.

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.
