Will Termites Eat Cedar Wood or Is It a Natural Barrier? Debunking Myths and Unraveling the Truth!

Outdoor furniture, decking, fence, and siding are often made from cedar wood. It is resistant to rust, decomposition, and insects because of its natural oils. However, do termites consume cedar wood? We’ll examine why cedar wood is an effective repellent against termite damage and how you may efficiently protect your wooden assets, from the repelling properties of cedar oil to the fascinating exceptions. Now, let’s get into the specifics.

Will termites eat cedar wood?

Cedar oil naturally repels termites, so they avoid cedar wood. Although cedar wood possesses inherent termite-repelling chemicals, termite damage is still a possibility. Cedar wood is ideal for outdoor furniture and building because it resists termites. However, the western subterranean termite has developed a tolerance for cedar oil and may damage cedar wood.  Over time, maintenance and preventative treatment can protect cedar furniture, shingles, timber, and more from termite hazards.

An Overview of Termites on Cedar Wood

Termites are tiny, colonial insects that eat the cellulose in wood and wood products. The preferred foods of the various kinds of termites vary. Underground termites dig tunnels to get to supplies of wood and reside there. Drywood termites do not need ground contact to infest seasoned timber. Live trees and untreated timber are vigorously attacked by Formosan termites.

All termites need cellulose, although certain species choose particular types of wood over others. Which woods are resistant to infestation may be determined by understanding termite behavior.

The Natural Durability of Cedar

The cypress family of conifer plants includes a variety of cedar trees. Oils, resins, and organic substances in its heartwood serve as natural insect deterrents and preservatives. Cedar is resistant to fungus, mold, mildew, and wood decay because of the compounds in it.

When exposed to outside weather, several varieties of cedar have a lifespan of more than 20 years. Termite infestation is less likely due to cedar’s ability to resist deterioration. However, untreated sapwood and weak spots in cedar may still harbor termites.

Do Termites Eat Red Cedar?

One of the cedar species that resists rot the best is red cedar. It is often crimson in hue and smells strongly of spices. Red cedar contains the organic compounds thujone and cedrol, which may keep termites away.

Red cedar is less susceptible to termites than typical timbers for outdoor furniture or gardening. It is not entirely resistant to termite harm, however. Long-term ground contact or dampness might gradually reduce its resistance. Red cedar may be protected against termites with regular examination and treatment.

The Exposure of Cedar Mulch

Cedar chip or shred mulch aids in weed control and soil moisture retention. Cedar mulch is inherently insect-resistant because of the oils it contains. However, it loses chemical power as it breaks down. Subterranean termites may be attracted by damp cedar mulch placed directly on the ground.

Replacement of worn-out mulch layers decreases termite attraction. Avoid putting mulch up against the house’s foundation. Maintain a few-inch separation between mulch beds and wood siding. Mulch beds should be kept away from water sources like downspouts.

Types of Cedar Mulch and Features

Cedar Mulch Type	Source	Aroma	Termite Repellent	Decomposition Rate	Use Cases
Eastern Red Cedar	Eastern Red Cedar trees	Strong, Distinct	High	Slow	Landscaping, Garden Beds, Pathways
Western Red Cedar	Western Red Cedar trees	Mild, Pleasant	Moderate	Moderate	Landscaping, Mulching, Aesthetic
Aromatic Cedar	Aromatic Cedar trees	Strong, Invigorating	High	Slow	Mulching, Pest Repellent, Fragrance
Spanish Cedar	Spanish Cedar trees	Mild, Sweet	Moderate	Moderate	Decorative, Fragrant Mulching

Can Termites Eat Through Cedar Lumber? 

Cedar timber is prized for its ability to withstand the elements and repel insects. Its inherent toughness may aid in preventing termite infestation. However, untreated sapwood found in cedar timber may still support termites. Once inside, they can jeopardize the building’s integrity.

While cedar timber reduces certain termite threats, complete protection cannot be guaranteed. Cedar’s resistance to termites is increased by preservation treatment. Combine termite-resistant elements like concrete, steel, or masonry with cedar timber. Regularly check for early indications of infestation.

Do Termites Infest Living Cedar Trees?

Termites are repelled by the oils found in living cedar trees. However, there are circumstances in which termites may attack live cedars. Formosan termites, for instance, may infiltrate living trees and feed vigorously on cellulose. The natural defenses of a tree are also weakened by drought stress.

There are still some repulsive properties in cedar tree mulch or wood chips. Mulch is resistant to termites, but with time, it degrades. Mulch beds should be kept away from cedar tree trunks. Inspect items made of dead wood and live trees for termites.

Can Termites Get Through Cedar Wood Siding?

Cedar wood siding adds aesthetic appeal to houses due to its inherent durability and texture. Additionally, rot, warping, and vermin cannot harm cedar siding. However, untreated cedar siding might be penetrated by termites under the correct circumstances. Vulnerability is impacted by elements such as moisture, soil contact, and wood type.

Keeping cedar siding up keeps termites at bay. Maintain siding 4 inches from roof lines and at least 6 inches above soil level. Give siding and other materials some room. Regularly check for termites, particularly close to the ground. Treatments with preservatives also increase cedar’s termite resistance.

Do Termites Eat Through Cedar Shingles?

As roofing and siding materials, cedar shingles provide a rustic appeal. The organic oils assist in warding off water and wood-boring insects. However, with time, exposure to moisture and light depletes protecting substances. Termites may enter via worn or damaged cedar shingles.

The key to avoiding termite problems is to maintain cedar shingles. Restore insect and water resistance by applying coatings. Any missing or broken shingles must be replaced immediately. To prevent moisture accumulation, increase ventilation. Check the shingles often for termites, particularly close to the eaves and roof edges.

How to Keep Termites Out of Cedar Decks?

Cedar decks in the backyard offer a beautiful outdoor living area. Cedar decking is attractive, long-lasting, and has some built-in insect protection. Decks are susceptible to termites due to ground contact, dampness, and garbage. Preventative maintenance protects cedar decking.

Avoid placing footings or posts directly in the ground. Use concrete piers or metal holders. Deck planks should be slanted and sealed. Fix any cracks that termites could use to enter. Look for tubes or swarms of shelter beneath the decks. For optimal protection, treat decking timber before installation.

Cedar Furniture and Termite Risks

Cedar patio furniture and outdoor accents are charming and weather-resistant. Cedar is resistant to rot and termites because of its natural chemicals. However, termites may still cause harm to furniture that is exposed to the soil or kept outside all year.

During the winter, keep cedar furniture inside a garage or shed. To prevent termites, submerge furniture legs in water cans or diatomaceous earth. Annually apply a protective sealant on cedar furniture. Regularly check for termites’ early warning signals, such as tiny holes or shelter tubes. Rapid infestation detection helps avoid extensive harm.

Conclusion

In domestic building and outdoor projects, cedar wood has several advantages. It offers protection against termites due to its inherent toughness and pest-resistance traits. Cedar, particularly over time, is not resistant to termite attack. The defenses of cedar against termites are strengthened by proper usage, maintenance, and preventative treatment. Keep an eye out for any prospective infestation’s first indications. Act quickly to reduce termite damage and maintain the beauty of cedar.
