While termites are known for their ability to consume and digest cellulose, the primary component of wood, there are some types of timber that are considered less attractive or resistant to termite infestation. These timbers may have natural properties or chemical treatments that make them less appealing to termites. However, it’s important to note that no wood is completely immune to termite attack, and termites can still infest and damage even the most resistant timbers given the right circumstances. Here are a few examples of timber types that are generally considered less susceptible to termite damage:

  • Hardwoods: Certain hardwood species are naturally more resistant to termites due to their density and natural oils or resins. Examples include jarrah, ironbark, blackbutt, and tallowwood. These hardwoods are known for their durability and are commonly used in construction and outdoor applications.
  • Treated timbers: Timber that has been treated with preservatives or chemicals to deter termites can provide enhanced resistance. Commonly used treatments include copper-based compounds (e.g., copper azole or copper chrome arsenate) or borate-based treatments. Treated timbers are often used in areas where termite exposure is high, such as in structural framing or in-ground applications.
  • Cypress pine: Cypress pine is a softwood species that naturally contains resins and oils that make it less appealing to termites. It is commonly used in fencing, decking, and outdoor applications.
  • Teak: Teak is a tropical hardwood that possesses natural oils and resins, making it resistant to termites, decay, and rot. It is often used in high-quality outdoor furniture and boat construction.

It’s important to remember that while these timbers are considered less attractive to termites, they are not termite-proof. Regular inspections, proper maintenance, and implementing preventive measures are still necessary to protect your property from termite infestations. Additionally, using termite-resistant materials in construction, such as concrete, steel, or composite materials, can help reduce the risk of termite damage. Consulting with a professional pest control expert or a building professional can provide further guidance on termite-resistant timber options and appropriate preventive measures for your specific situation.
