Termites can be found across much of the United States, and their ability to quietly chew through wooden structures makes them one of the most destructive household pests. While no wood is completely termite-proof, certain types are naturally less appealing to termites. Knowing which woods termites are less likely to eat can help when building, renovating, or choosing outdoor materials.
That said, even “termite-proof woods” can eventually be attacked, which is why professional inspections and treatments remain the most reliable defense.
Termites feed on cellulose, which is found in nearly all types of wood. That means they can attack most wood, but they don’t eat all types equally. Softer woods with higher moisture content, like pine, are especially attractive, while dense or naturally oily woods, such as teak or cedar, are less appealing.
Some woods naturally resist termites better than others. Their density, oils, or chemical makeup make them less appealing as a food source. While these termite-resistant woods can reduce the risk of damage, it’s important to remember that no wood is completely termite-proof —especially if wood is damp or in direct contact with soil—termites may eventually feed on it.
Cedar contains natural resins and aromatic oils that deter many insects, including termites. While it’s more resistant than many other woods, cedar can still be attacked if it becomes damp or weathered over time.
Redwood is dense and naturally resistant to both moisture and insects. It’s often used for outdoor projects like decks and fencing. Still, if redwood is in direct contact with soil or stays wet, termites may eventually exploit it.
Teak is one of the most durable hardwoods, thanks to its natural oils and density. It’s widely used in outdoor furniture and boat building. While termites are less likely to feed on teak, its high cost makes it impractical for most structural uses.
Although not a natural wood, pressure-treated lumber can be protected against termite damage. It’s often used for framing, decks, and other structures where wood touches soil.
Pressure-treated wood is built to resist termites and decay because it’s infused with preservatives that make the wood less appealing as a food source.
In most cases, termites avoid it—but no wood is completely safe. Over time, if the protective chemicals wear down, especially in older or weathered lumber, termites may still attack. They can also exploit cracks, cut edges, or untreated sections of the wood.
For that reason, pressure-treated lumber is a good choice for decks, posts, and framing that contact soil, but it should be paired with regular inspections and professional termite prevention for long-term protection.
While some woods naturally resist termites, others are highly vulnerable. Pine and other softwoods are at the top of the list. Their lower density and ability to retain moisture make them an easy and attractive target for termites. Homes built with untreated pine framing, siding, or flooring can be especially at risk if termites gain access.
Termites don’t stop at softwoods, though. Many hardwoods are also susceptible, particularly when they’re damp or come into direct contact with soil. Untreated oak, maple, and birch, for example, may provide enough cellulose and moisture to sustain a growing colony.
Outdoor wooden structures like decks, fences, and garden beds made from untreated wood are also frequent targets, since they are often exposed to soil and weather conditions that create the moisture termites need.
Even though some woods offer more protection, no type of wood is entirely safe from termites. Over time, exposure to moisture, soil, or weathering can make any wood attractive to a colony. The best way to rely on professional prevention and treatment rather than wood choice alone.
Choosing termite-resistant wood is a smart step, but it won’t stop an infestation on its own. The best protection comes from combining smart building choices with professional termite control. Regular inspections, soil treatments, and baiting systems provide long-term protection, regardless of the materials used in your home.
