Sustainable Wood that is Not Affected by Termites
Termite-Resistant Wood Species: Natural Protection for Sustainable Structures
What are termites?
Termites are small, social insects that belong to the order Isoptera. They are known for their ability to digest cellulose in wood, making them a serious threat to wooden structures and furniture. Termites live in colonies and can cause significant damage to buildings, often without being visible from the outside.

Why termite-resistant wood species are important
Using wood species that are naturally resistant to termites offers several benefits:
- Extends the lifespan of wooden structures
- Reduces the need for chemical treatments
- Saves costs in the long run
- Contributes to sustainable building
Overview of termite-resistant wood species
| Wood Species | Origin | Resistance Level | Main Applications |
|---|---|---|---|
| Teak (Tectona grandis) | Southeast Asia | Very high | Outdoor furniture, shipbuilding, flooring |
| Iroko (Chlorophora excelsa) | Africa | High | Outdoor furniture, flooring, cladding |
| Cumaru (Dipteryx odorata) | South America | Very high | Decking, flooring, outdoor furniture |
| Red Cedar (Thuja plicata) | North America | High | Cladding, roofing, fences |
| Padouk (Pterocarpus soyauxii) | Africa | High | Flooring, furniture, decorative applications |
| Jarrah (Eucalyptus marginata) | Australia | Very high | Outdoor furniture, decking, construction work |
| Mahogany (Swietenia spp.) | Central and South America | Moderate to high | High-quality furniture, flooring, boats |
Termite-resistant wood species from Southeast Asia: Merbau
In addition to Teak, Merbau (Intsia bijuga) is an excellent choice from Southeast Asia:
- High natural resistance to termites
- Durable and stable
- Suitable for both indoor and outdoor applications
- Beautiful, warm reddish-brown color
Merbau is often used for flooring, decking, stairs, and furniture.
Sustainability and Environmental Considerations
- Choose wood from sustainably managed forests
- Look for certifications like FSC or PEFC
- Consider local wood species to reduce transportation costs
- Balance sustainability with availability and costs
Why these wood species offer resistance
The natural resistance to termites comes from various factors:
- Natural oils and extractives: Toxic or repellent to termites
- High density: Difficult for termites to burrow into
- Resins and tannins: Fungicidal and insecticidal properties
- Silica content: Makes the wood harder and more difficult to digest
Prevention
Choose termite-resistant wood when building or renovating
Maintenance
Regular inspection and treatment of wood
Protection
Use natural or chemical preservatives if necessary
Sustainability
Opt for sustainably produced wood with certification
Frequently Asked Questions
Are termite-resistant wood species completely immune to termites?
No, even the most resistant wood species are not completely immune. They offer higher resistance, but under extreme conditions, termites can still cause damage. Regular inspection remains important.
Are termite-resistant wood species more expensive?
Generally, termite-resistant wood species are more expensive to purchase. However, in the long run, they can save costs due to their longer lifespan and reduced need for treatments.
Can I combine termite-resistant wood with other wood species?
Yes, that is possible. Use termite-resistant wood for critical structural elements or high-risk areas, and combine it with other wood species for less vulnerable applications.
Conclusion
Choosing wood species that are naturally resistant to termites is an effective strategy for enhancing the durability of wooden structures and furniture. Species such as Teak, Iroko, Cumaru, and Merbau not only provide protection against termites but also offer aesthetic benefits and versatility in use. When selecting wood, it is important to consider sustainability aspects and choose certified wood from responsibly managed forests. By making conscious choices in wood usage, we can contribute to both the longevity of our structures and the protection of our forests.
