Do Teak and Sal Wood Get Wood Borers?

Teak and sal are prized in Indian homes for doors, frames and furniture, and they are often described as borer-proof. They are naturally resistant, but resistance is not immunity.

The short answer

Heartwood of teak and sal is naturally durable and resists most borers and termites, but the sapwood is vulnerable, and poor-quality, mixed or young timber can be attacked. Furniture sold as teak may include sapwood or other woods. Check for exit holes, powder and soft spots, choose seasoned heartwood, seal the surface and keep moisture low. Infested pieces need professional identification and treatment.

Why teak and sal resist borers

• Natural oils and extractives in heartwood discourage insects.
• Dense wood is harder for larvae to tunnel.
• Properly seasoned heartwood is the most durable part.

Where they are still vulnerable

• Sapwood, which is lighter and softer.
• Young or fast-grown plantation timber with less heartwood.
• Pieces mixed with other woods or sold as teak-look.
• Damp, poorly ventilated or unfinished areas.

What to check when buying

1. Ask whether the piece is heartwood and properly seasoned.
2. Look for exit holes and powder, especially on hidden faces.
3. Inspect joints and the underside.
4. Buy from sellers who give clear information.

Protecting teak and sal

• Apply a suitable oil, polish or sealant on all faces.
• Keep wood away from persistent damp.
• Inspect doors, frames and furniture each 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.
