15 Termite Resistant Wood Species for Outdoor Projects

If you are building a deck, fence, pergola, outdoor furniture, or any other exterior structure, choosing the right wood is one of the most important decisions you can make. Outdoor wood faces constant exposure to moisture, sunlight, insects, and changing weather. Among these threats, termites are one of the most damaging because they feed on wood and can weaken a structure over time.

While no wood is completely termite proof, some wood species naturally resist termites much better than others. These woods contain natural oils, dense fibers, or chemical compounds that make them less attractive to termites. Choosing termite resistant wood can increase the life of your outdoor project and reduce maintenance costs.

In this guide, you will learn about 15 termite resistant wood species, their benefits, common uses, and why they are popular for outdoor construction.

How to Make Outdoor Wood Last Longer

Even the most termite resistant wood needs proper care. Following a few simple maintenance steps can greatly increase its lifespan.

Keep Wood Dry

Standing water encourages decay and insect activity. Make sure decks, fences, and furniture have proper drainage and airflow.

Apply a Protective Finish

A high-quality exterior oil, stain, or sealant helps protect wood from moisture and sunlight.

Inspect Regularly

Check your outdoor structures once or twice a year for signs of termites, cracks, or moisture damage. Early detection prevents expensive repairs.

Keep Wood Away From Soil

Direct contact with soil increases the chance of termite attacks. Whenever possible, use concrete footings or metal supports.

Clean the Surface

Remove dirt, leaves, and debris regularly to prevent moisture buildup and mold growth.

Natural Resistance vs Pressure Treated Wood

Many homeowners wonder whether they should choose naturally termite resistant wood or pressure treated lumber.

Naturally resistant wood contains oils, chemicals, or dense fibers that discourage termites without chemical treatment. These woods are often more attractive and can last for decades.

Pressure treated wood has preservatives forced deep into the wood to improve resistance against insects and decay. It is usually more affordable but may require more maintenance over time.

For premium outdoor projects where appearance and longevity matter, natural hardwoods are often the preferred choice.

• Best overall: Ipe
• Best value tropical hardwood: Cumaru
• Best premium furniture wood: Teak
• Best affordable option: Cedar
• Best for fences: Cypress
• Best domestic hardwood: Black Locust
