Honestly, I get this question all the time from friends staging their backyards. You find a gorgeous acacia or teak bench, and the first nightmare is a colony of termites turning it into sawdust. So let’s talk about it like we’re just hanging out on the deck.
The short answer is: it completely depends on the wood type and how it was built. Not every wooden outdoor bench is a termite magnet, and many are specifically treated to prevent exactly that. But you can’t just trust the label "outdoor bench" and forget about it.
First, let’s break down the wood itself. There are timbers that termites genuinely dislike, not because of some chemical we added, but because of their own natural oils and density. Teak, cedar, and redwood are the classics. A high-quality cedar bench naturally contains oils that repel insects and resist rot. Termites might crawl across it, but they won’t set up a buffet there. It’s like how some people naturally repel mosquitoes — it’s just in their chemistry. If you buy a bench made from solid heartwood of these species, you’re already way ahead. The wood is naturally resistant, no extra treatment needed, though the resistance will soften a little over many, many years as the outer layer weathers. You can lightly sand and oil it to refresh that defense.
Then you have pressure-treated wood. This is usually pine or a softer timber that’s been thrown into a massive cylinder and pumped with chemical preservatives under pressure. The greenish or brownish tint you sometimes see? That’s the treatment. Modern pressure-treated lumber, particularly the stuff used for outdoor furniture labeled “above-ground use,” is incredibly effective against termites and fungal decay. The active copper-based compounds are a deterrent. So if your bench is made from pressure-treated pine, you can relax. The downside is it doesn’t feel as premium, it can crack a bit, and you probably won’t want it for that rustic farmhouse aesthetic if the coloring is off. But it’s safe from pests.
Now, here’s the tricky part. What if you bought a beautiful bench made from untreated softwood like simple pine, fir, or a generic "hardwood" that isn’t naturally durable? That can attract termites, especially if you place it directly on damp soil or mulch. Termites are smart little architects. They build mud tubes to reach wood that sits on the ground, hidden from the sun. A cheap bench with legs resting in a flower bed is basically a welcome sign. And raw, untreated sapwood of almost any tree — even oak — is candy to them.
You can totally use an untreated softwood bench if you seal it. I’m talking about a proper marine-grade varnish, exterior polyurethane, or a penetrating oil finish that seals the surface. The key is maintenance. If you don’t let water soak in and cause the wood to stay soft and moist, termites won’t find it nearly as inviting. They need moisture. A dry bench in the sun is a desert to them. So, slapping on a fresh coat of sealer once a year isn’t just cosmetic — it’s your bench’s armor.
And if you have an older bench that wasn’t treated? You’re not doomed. I’ve revived a second-hand bench by brushing on a borate-based wood preservative. It soaks right in and makes the wood toxic to termites and wood-boring beetles without being scary to humans or pets once dry. You can even apply it to unfinished wood and paint over it. It’s a clever, low-toxicity fix.
Where you place the bench matters more than you think. I tell everyone: keep the legs off direct soil. Put them on stone pavers, gravel, or a concrete patio. Not only does that prevent wicking moisture, but it also breaks the hidden highway termites use to travel from the ground into your bench without you seeing. Regularly lift the bench and check the leg bottoms for tiny mud trails. If you see any, a quick scrape and a localized spray of orange oil or a termite foam right into the joints will sort it out before they get deep.
Also, don’t panic over a few flying termites landing on it during mating season. A swarm just looking for a home won’t automatically destroy a bench resting in dry, open air. They need soil contact or very damp, rotting wood to establish a colony. The bench itself rarely becomes the nest.
So, if you’re shopping right now, look at the product description. Words like “100% solid teak,” “natural cedar,” or “pressure-treated pine” are your go-ahead. Avoid descriptions that just say “solid wood” with no specification, especially at a suspiciously low price. If you already own a bench and aren’t sure, just drill a tiny, discreet hole in the underside. Fresh-scented, tight wood? You’re good. Damp, spongy, or smelling like a forest floor? Time for a borate treatment and sealing.
In the end, I’ve had a Western red cedar bench on raw gravel for eight years. Not a single nibble. It weathers to a silver patina, and termites just aren’t interested. The real danger isn’t the bench material — it’s neglect. Keep it dry, keep it treated, and keep it off the dirt. You’ll be enjoying your outdoor seat long after other things have come and gone.
