The Natural Powerhouse: How Cedar Resists Rot and Insects (Explained)

When you choose outdoor log furniture for your patio, deck, or garden, you want peace of mind that it will last. No one wants to deal with rot, decay, or unwelcome insect guests. That's why at Lakeland Mills, we proudly craft much of our collection from Northern White Cedar, a wood species renowned for its incredible natural resistance.

But how exactly does cedar accomplish this feat? Let's dive into the fascinating science behind why cedar is nature's perfect choice for durable rustic furniture and log furniture designed for the great outdoors.

Nature's Own Preservatives: Why Cedar Doesn't Rot Easily

The secret to cedar's remarkable resistance to rot and decay lies within its unique chemical composition, specifically in the heartwood. Cedar trees produce a group of compounds known as thujaplicins (particularly prominent in Western Red Cedar, a close relative of Northern White Cedar in terms of properties) and other extractives. These natural compounds act as powerful fungicides and antimicrobials.

How it Works:

• Fungicidal Properties: When fungi (the organisms that cause wood rot) attempt to colonize cedar wood, these thujaplicins interfere with their growth and ability to break down wood fibers. It's like a natural defense system built right into the timber.

• Reduced Moisture Absorption: Cedar, especially Northern White Cedar, has a naturally low density and a cellular structure that makes it less prone to absorbing and holding moisture. Rot-causing fungi need moisture to thrive. By minimizing water uptake, cedar creates an inhospitable environment for these destructive organisms.

• Dimensional Stability: Because it absorbs less moisture, cedar is less likely to swell, shrink, warp, or crack when exposed to the elements. This dimensional stability also contributes to its resistance against rot, as cracks and splits can create entry points for moisture and decay.

Common Question: Does cedar ever rot? While highly resistant, no wood is entirely immune if exposed to constant moisture and lack of ventilation over extremely long periods (e.g., direct contact with wet soil). However, cedar's natural defenses significantly slow down the decay process, allowing it to far outlast many other wood species in outdoor conditions. For instance, our Lakeland Mills cedar log furniture is known to last 15 years or more outdoors, even unfinished, in Michigan's varying climate.

Keeping the Pests at Bay: Cedar's Insect Repelling Power

Beyond rot, insects can be a major threat to outdoor furniture. Here again, cedar stands out. The same natural oils and aromatic compounds that deter fungi also act as a natural insect repellent.

How it Works:

• Aromatic Compounds: Cedar's distinctive, pleasant aroma (to humans, anyway!) is largely due to volatile oils containing compounds like cedrol and thujone. For insects like moths, carpet beetles, ants, and even mosquitoes, these compounds are highly unpleasant and disruptive.

• Pheromone Disruption: For many insects, these compounds can interfere with their sensory systems, confusing their ability to locate mates, food sources, or suitable places to lay eggs. This "disorientation" drives them away from cedar wood.

• Anti-Feedant Properties: Some compounds in cedar can even act as anti-feedants, discouraging insect larvae from consuming the wood itself.

Common Concern: Will cedar completely eliminate all bugs from my yard? While cedar is a powerful natural repellent, it's important to understand it's a deterrent, not an insecticide for your entire property. It will make your cedar log swings, log porch swings, adirondack chairs, and cedar picnic tables far less appealing to wood-boring insects and common outdoor pests, keeping them off your furniture. It's an excellent, non-toxic way to protect your furniture without relying on harsh chemicals.
