Rubberwood Furniture and Borers: Why It Is So Vulnerable

Rubberwood is widely used for affordable beds, tables, chairs and kitchen furniture. It is attractive and sustainable, but it is also one of the woods most commonly attacked by borers.

The short answer

Rubberwood has a high starch and sugar content, which attracts powderpost-type beetles, and it is not naturally durable. Good-quality furniture is treated and kiln-dried at the factory, and treatment quality varies widely. Reduce risk by buying from reliable makers, checking for holes and powder before purchase, sealing all faces and keeping the furniture dry. Infested pieces need professional treatment.

Why rubberwood is vulnerable

• High starch and sugars feed larvae.
• Low natural durability compared with teak or sal.
• Poorly dried or untreated timber attracts beetles.
• Raw, unfinished surfaces on hidden faces are easy targets.

Role of factory treatment

• Kiln drying and preservative treatment reduce risk.
• Not all makers treat adequately.
• Ask what treatment was used and for any documentation.

Signs of infestation

• Tiny round exit holes.
• Fine powder beneath beds, tables or chairs.
• Soft, crumbling wood in legs and rails.

Protecting rubberwood furniture

1. Buy from sellers who treat and document it.
2. Check hidden faces and joints before buying.
3. Seal all faces with polish or sealant.
4. Keep furniture away from damp walls.
5. Inspect twice a year.

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.

Do borers spread from rubberwood to other furniture?

They can, so act promptly.

Is paint enough protection?

It helps, but only if all faces are sealed.
