Let’s delve into the world of wood, specifically cedar, and the ever-present threat of termites. This isn’t just about identifying pests; it’s about understanding wood, its properties, and how to protect it. While many focus on the immediate damage termites can cause, I want to show you the hidden benefits of understanding wood pests – how it can save you money, improve your woodworking projects, and even enhance your property value.

Cedar and Termites: Identifying Wood Pests (Expert Woodcare Tips)

As a woodworker and someone who has spent countless hours felling trees, processing logs, and preparing firewood, I’ve seen firsthand the devastation termites can wreak. But I’ve also learned that with the right knowledge and preventative measures, you can keep your wood safe and sound. This guide will walk you through everything you need to know about cedar, termites, and how to protect your wood.

Why Understanding Wood Pests is Crucial

Many people see dealing with termites as a reactive measure – something you do after you find an infestation. I believe in a proactive approach. Understanding wood pests, especially termites, allows you to:

Save Money: Early detection and prevention are far cheaper than repairing extensive damage.
Improve Woodworking Projects: Knowing how to select and treat wood will result in more durable and long-lasting projects.
Enhance Property Value: A well-maintained home, free from wood-destroying pests, is a valuable asset.
Choose the Right Wood for the Job: Understanding the natural resistance of different wood species to pests allows you to select appropriate materials for various applications.
Minimize Environmental Impact: By focusing on preventative measures and targeted treatments, you can reduce your reliance on harsh chemicals.

What Are Termites? A Woodworker’s Perspective

Termites are social insects that feed on cellulose, the main structural component of wood. They live in colonies and can cause significant damage to wooden structures. From a woodworker’s perspective, termites are more than just pests; they are wood’s natural enemy.

Key Terminology:

Cellulose: The main structural component of plant cell walls, including wood.
Colony: A social group of termites, typically consisting of workers, soldiers, and reproductives.
Worker Termites: The most numerous members of the colony; responsible for foraging, feeding, and building.
Soldier Termites: Specialized termites with large mandibles, responsible for defending the colony.
Reproductive Termites (Alates): Winged termites that fly out to establish new colonies.
Subterranean Termites: Termites that live in the soil and build mud tubes to reach wood.
Drywood Termites: Termites that live entirely within dry wood and do not require contact with the soil.
Dampwood Termites: Termites that infest wood with high moisture content.

Cedar: A Natural Defense?

Cedar is often touted as being naturally resistant to termites. While there’s some truth to this, it’s not a foolproof shield.

The Good News:

Cedarwood contains natural oils, such as thujone, that are toxic to termites and other insects.
Aromatic red cedar, in particular, is known for its insect-repelling properties.
Heartwood (the inner core of the tree) is more resistant than sapwood (the outer layer).

The Reality:

Termites can still attack cedar, especially if it’s old, weathered, or has lost its natural oils.
Cedar is not immune to all types of termites.
The level of resistance varies depending on the species of cedar and its age.

My Experience: I once built a shed using primarily cedar, believing it would be termite-proof. A few years later, I found signs of termite activity near the base, where the cedar came into contact with the ground. This experience taught me that even naturally resistant woods require proper protection.

Identifying Termites: Know Your Enemy

Before you can protect your wood, you need to know how to identify termites and their signs.

Types of Termites:

Subterranean Termites: These are the most common and destructive type of termite. They live in the soil and build mud tubes to reach wood.
- Signs: Mud tubes on walls or foundations, hollow-sounding wood, swarmers (winged reproductives) near your home.
Drywood Termites: These termites live entirely within dry wood and do not require contact with the soil.
- Signs: Frass (termite droppings) that look like small, dry pellets, hollow-sounding wood, swarmers emerging from wood.
Dampwood Termites: These termites infest wood with high moisture content.
- Signs: Infestation in damp or decaying wood, often near water sources.

Visual Identification:

Workers: Creamy-white, wingless, about ¼ inch long.
Soldiers: Similar to workers but with large, dark-colored heads and mandibles.
Reproductives (Alates): Dark-bodied with translucent wings, about ½ inch long.

Distinguishing Termites from Ants:

Antennae: Termites have straight antennae, while ants have bent antennae.
Waist: Termites have a broad waist, while ants have a narrow, pinched waist.
Wings: Termite wings are equal in size, while ant wings are unequal in size.

Case Study: I was once called to a friend’s house who was convinced he had an ant infestation. Upon closer inspection, I noticed the insects had straight antennae and a broad waist – clear signs of termites. Early identification saved him from significant damage.

Preventing Termite Infestations: A Proactive Approach

Prevention is always better than cure. Here are some steps you can take to prevent termite infestations:

Eliminate Moisture Sources: Termites thrive in moist environments. Fix leaky pipes, improve drainage, and ensure proper ventilation.
- My Tip: Regularly check your crawl space and basement for signs of moisture. A dehumidifier can be a worthwhile investment.
Remove Wood-to-Ground Contact: Termites can easily access wood that is in direct contact with the soil. Use concrete or metal barriers to separate wood from the ground.
- Example: When building a deck, use pressure-treated lumber for the posts and ensure they are set in concrete footings that extend above ground level.
Maintain a Clear Perimeter: Keep shrubs, trees, and mulch away from your foundation. These can provide a bridge for termites to reach your home.
- Recommendation: Maintain a 12-18 inch gap between your foundation and any vegetation or mulch.
Use Termite-Resistant Materials: When building or renovating, consider using termite-resistant materials such as pressure-treated lumber, concrete, or steel.
- Note: Pressure-treated lumber is treated with chemicals that make it toxic to termites. Always wear appropriate safety gear when handling pressure-treated lumber.
Regular Inspections: Inspect your home regularly for signs of termites. Pay close attention to areas where wood comes into contact with the ground or where there is moisture.
- Pro Tip: Use a flashlight and a screwdriver to probe wood for hollow spots.
Proper Wood Storage: Store firewood and lumber away from your home and off the ground.
- My Method: I stack my firewood on pallets, covered with a tarp, at least 20 feet away from my house. This prevents termites from using the firewood as a stepping stone to my home.
Soil Treatment: Consider treating the soil around your foundation with a termiticide. This can create a barrier that prevents termites from entering your home.
- Caution: Termiticides are chemicals and should be used with caution. Follow the manufacturer’s instructions carefully and wear appropriate safety gear. Consult with a professional pest control company for advice.

Treating Termite Infestations: When Prevention Fails

Despite your best efforts, termites may still find their way into your wood. Here are some treatment options:

Bait Systems: Termite bait systems consist of stations placed around your property that contain a slow-acting poison. Termites feed on the bait and carry it back to the colony, eventually killing the entire colony.
- Benefits: Effective for eliminating entire colonies, relatively low toxicity.
- Drawbacks: Can take several months to work, requires regular monitoring and maintenance.
Liquid Termiticides: Liquid termiticides are applied to the soil around your foundation, creating a barrier that prevents termites from entering your home.
- Benefits: Fast-acting, can provide long-term protection.
- Drawbacks: Requires professional application, can be expensive.
Direct Wood Treatment: This involves applying termiticides directly to infested wood.
- Benefits: Effective for treating localized infestations.
- Drawbacks: May not eliminate the entire colony, requires careful application.
Fumigation: This involves tenting your entire home and filling it with a fumigant gas.
- Benefits: Effective for eliminating all termites in your home.
- Drawbacks: Expensive, requires vacating your home for several days, can be hazardous.

Choosing the Right Treatment: The best treatment option depends on the type and extent of the infestation, as well as your budget and preferences. Consult with a professional pest control company to determine the best course of action.

My Approach: For small, localized infestations, I’ve had success using borate-based wood preservatives. These are relatively non-toxic and can be applied directly to the wood. However, for larger infestations, I always recommend calling a professional.

Cedar Selection and Treatment: Maximizing Resistance

Not all cedar is created equal. Here’s what to look for when selecting cedar for your projects:

Heartwood vs. Sapwood: Heartwood is the inner core of the tree and is more resistant to termites and decay than sapwood, which is the outer layer. Choose heartwood whenever possible.
- Identification: Heartwood is typically darker in color than sapwood.
Species of Cedar: Different species of cedar have varying levels of resistance to termites. Aromatic red cedar is generally considered to be the most resistant.
Kiln-Dried vs. Air-Dried: Kiln-dried cedar is less likely to warp or crack, but air-dried cedar may retain more of its natural oils, making it more resistant to insects.
Treatment Options: Even with cedar, consider applying a wood preservative to further enhance its resistance to termites and decay.
- Borate-Based Preservatives: These are relatively non-toxic and can be applied to the wood before or after installation.
- Oil-Based Preservatives: These penetrate the wood deeply and provide long-lasting protection.

Project Example: When building a fence, I used cedar posts treated with a borate-based preservative. This provided an extra layer of protection against termites and decay, ensuring the fence would last for many years. I chose 4×4 posts, 8 feet long, and buried them 2 feet deep in concrete. Each post cost approximately $25, and the borate treatment added about $5 per post.

Firewood and Termites: A Hidden Danger

Firewood can be a breeding ground for termites. Here’s how to protect your home:

Store Firewood Away from Your Home: As mentioned earlier, store firewood at least 20 feet away from your house.
Stack Firewood Off the Ground: Use pallets or racks to keep firewood off the ground.
Cover Firewood: Cover firewood with a tarp to protect it from moisture.
Inspect Firewood Regularly: Look for signs of termites or other wood-boring insects.
Burn Firewood Quickly: Don’t let firewood sit around for too long. Burn it as soon as possible.

My Firewood Routine: I typically process firewood in the late summer and early fall, allowing it to season over the winter. I use a hydraulic log splitter with a 25-ton capacity to split the wood into manageable pieces. The splitter cost me around $1,500, but it has saved me countless hours of manual labor. I stack the firewood in rows, leaving space for air circulation, and cover it with a tarp. I also rotate the stacks periodically to ensure even drying.

Seasoning Firewood: Seasoning is the process of drying firewood to reduce its moisture content. This makes it easier to burn and reduces the risk of creosote buildup in your chimney.

Green Wood: Freshly cut wood that has a high moisture content.
Seasoned Wood: Wood that has been dried for at least six months to reduce its moisture content.

Benefits of Seasoning:

Easier to Burn: Seasoned wood burns hotter and more efficiently.
Less Smoke: Seasoned wood produces less smoke.
Reduces Creosote Buildup: Creosote is a flammable substance that can build up in your chimney and cause a fire.

Drying Time: The drying time for firewood depends on the type of wood, the climate, and how it is stacked. As a general rule, hardwoods (such as oak and maple) take longer to season than softwoods (such as pine and fir).

Chainsaws, Axes, and Log Splitters: Tools of the Trade

As someone who spends a lot of time processing wood, I rely on a variety of tools. Here are some of my favorites:

Chainsaws: Essential for felling trees and cutting logs into manageable lengths.
- My Choice: Stihl MS 271 Farm Boss. It’s a reliable and powerful chainsaw that can handle most jobs. I use a 20-inch bar and chain.
- Safety First: Always wear appropriate safety gear when using a chainsaw, including a helmet, eye protection, ear protection, gloves, and chaps.
Axes: Useful for splitting small logs and kindling.
- My Favorite: Gransfors Bruks splitting axe. It’s a high-quality axe that is well-balanced and easy to use.
Log Splitters: Make splitting large logs much easier and safer.
- My Recommendation: Hydraulic log splitter with a 25-ton capacity. It can handle most types of wood.
Measuring Tools: A good tape measure and a moisture meter are essential for ensuring accurate cuts and proper seasoning.
Personal Protective Equipment (PPE): Safety glasses, gloves, ear protection, and steel-toed boots are crucial for protecting yourself from injury.

Tool Maintenance: Regularly maintain your tools to ensure they are in good working order. This includes sharpening your chainsaw chain, cleaning your axe, and lubricating your log splitter.
