Do Ants Like Cedar? (5 Key Signs Woodworkers Must Know)
Do Ants Like Cedar? Ever wondered if those tiny six-legged creatures, ants, have a penchant for cedar like we do? I have, and that’s what led me down a fascinating path of discovery. As someone who’s spent a good chunk of my life surrounded by sawdust and the sweet smell of freshly cut timber, I’ve learned a thing or two about wood – and the critters that love (or hate) it. Cedar, with its distinct aroma and reputation for natural repellency, often sparks the question: is it truly ant-proof?
The truth, as with most things in woodworking, is a bit more nuanced than a simple yes or no. Today, I’m going to share my insights, gleaned from years of experience and a bit of personal experimentation, on whether ants like cedar. I’ll also give you five key signs that woodworkers must know to protect their projects. So, grab a cup of coffee, settle in, and let’s dive into the world of ants and cedar!
The Allure (or Lack Thereof) of Cedar for Ants: An Overview
Before we get into the nitty-gritty, let’s establish a foundational understanding of what makes cedar unique. Cedar is a softwood known for its aromatic oils, specifically thujone, which gives it that characteristic scent. These oils are what make cedar naturally resistant to decay, insects, and even some fungi. This makes it a popular choice for outdoor projects like decks, siding, and fences.
However, the term “ant-proof” is a bit of a misnomer. While cedar does possess properties that deter ants, it’s not an impenetrable fortress. The effectiveness of cedar against ants depends on several factors, including the type of cedar, the species of ant, and the overall environment.
My Personal Encounter with Cedar and Ants
I remember one summer building a beautiful cedar chest for my daughter. I was so proud of the craftsmanship, the tight joints, and the smooth finish. I even lined the interior with cedar shavings, thinking I was creating the ultimate insect-resistant storage solution.
Imagine my surprise when, a few weeks later, I noticed a small trail of ants marching across the lid! It was a humbling experience, and it taught me a valuable lesson: cedar is a deterrent, not a guarantee. This led me to research further and implement additional preventative measures.
Debunking the Myth: Cedar is NOT Ant-Proof
The biggest misconception I want to address right off the bat is the idea that cedar is completely immune to ant infestations. While cedar’s natural oils are repellent, they don’t kill ants. Over time, these oils can evaporate, reducing the wood’s effectiveness. Furthermore, some ant species are simply more tolerant of cedar than others.
Think of it like this: cedar is like a well-guarded gate. It makes it harder for ants to enter, but a determined group can still find a way in. And if there’s a compelling reason for them to do so – like a food source or a protected nesting site – they’re even more likely to breach the defenses.
5 Key Signs Woodworkers Must Know
Now, let’s get down to the practical stuff. Here are five key signs that woodworkers must be aware of to protect their cedar projects from ant infestations:
1. Visible Ant Trails Near or On Cedar Projects
This is the most obvious sign, but it’s important to catch it early. Look for small, consistent trails of ants leading to or from your cedar project. These trails often indicate that ants have found a way to navigate the cedar’s defenses and are actively using it as a pathway or, worse, as a nesting site.
What to do: Immediately investigate the source of the trail. Follow it back to where the ants are coming from and try to identify the ant species. Clean the area thoroughly with a vinegar-water solution to disrupt the ant trails and remove any scent markers.
2. Frass or Sawdust Accumulation Around the Wood
Frass is the term for insect excrement, and it often looks like fine sawdust. If you notice small piles of frass near your cedar project, it’s a strong indication that ants (or other wood-boring insects) are actively tunneling into the wood.
What to do: Carefully inspect the area where you found the frass. Look for small holes or cracks in the wood that could be entry points. Use a small probe to check for soft or damaged wood beneath the surface. If the infestation is localized, you may be able to treat it with a borate-based wood preservative.
3. Soft or Spongy Areas in the Cedar
This is a sign of advanced infestation. If you press on the cedar and it feels soft or spongy, it means the ants have been actively tunneling through the wood, weakening its structure.
What to do: This usually requires more drastic measures. Depending on the extent of the damage, you may need to replace the affected section of wood. Before replacing, treat the surrounding area with a wood preservative to prevent further infestation.
4. Ant Nests Located Nearby
If you have ant nests in your yard or near your workshop, your cedar projects are at a higher risk of infestation. Ants are opportunistic creatures, and they’ll readily explore any potential food source or nesting site within their territory.
What to do: Take steps to control the ant population around your property. This could involve using ant baits, sealing cracks and crevices in your foundation, and removing any potential food sources.
5. Changes in the Cedar’s Aroma
As I mentioned earlier, cedar’s aromatic oils are what make it repellent to ants. If you notice that the cedar’s scent is fading, it means the oils are evaporating, and the wood is becoming more vulnerable to infestation.
What to do: Rejuvenate the cedar’s aroma by lightly sanding the surface to expose fresh wood. You can also apply cedarwood oil to the surface to replenish the natural oils.
Understanding Different Types of Cedar
Not all cedar is created equal. There are several different species of cedar, each with its own unique properties and levels of resistance to insects. Here’s a brief overview of some common types:
- Western Red Cedar: This is one of the most popular choices for outdoor projects due to its natural durability and resistance to decay and insects. It has a strong, distinct aroma and a beautiful reddish-brown color.
- Eastern Red Cedar: While technically a juniper, Eastern Red Cedar is often referred to as cedar due to its similar aromatic properties. It’s known for its strong scent and is commonly used for lining closets and chests to repel moths.
- Spanish Cedar: This is a tropical hardwood that’s often used for making cigar boxes and humidors due to its ability to maintain humidity and repel insects. It has a milder scent than Western Red Cedar and is less resistant to decay.
- Aromatic Cedar: This term generally refers to Eastern Red Cedar or other cedars with a strong aroma. The stronger the aroma, the more repellent the cedar is likely to be to insects.
Data Point: Western Red Cedar heartwood contains about 3-5% extractives (including thujone), which contribute to its decay and insect resistance. Eastern Red Cedar contains a similar amount of volatile oils. (Source: USDA Forest Service)
Choosing the Right Cedar for Your Project
When selecting cedar for your project, consider the following factors:
- Intended Use: If you’re building something that will be exposed to the elements, like a deck or fence, Western Red Cedar is a good choice. For indoor projects like closets or chests, Eastern Red Cedar is a great option.
- Budget: Cedar can be more expensive than other types of wood, so factor that into your budget.
- Aroma: Choose a cedar with a strong, distinct aroma. This is an indication that the wood contains a high concentration of repellent oils.
- Source: Purchase cedar from a reputable supplier to ensure that you’re getting high-quality wood that’s been properly dried and stored.
Enhancing Cedar’s Natural Defenses
Even the best cedar can benefit from a little extra protection. Here are some ways to enhance cedar’s natural defenses against ants and other insects:
- Wood Preservatives: Apply a borate-based wood preservative to the cedar before construction. Borates are effective at killing wood-boring insects and preventing future infestations.
- Sealants: Seal the cedar with a clear coat of sealant to help prevent moisture from penetrating the wood. Moisture can attract ants and other insects.
- Cedarwood Oil: Apply cedarwood oil to the surface of the cedar to replenish the natural oils and enhance the aroma.
- Proper Ventilation: Ensure that your cedar project is well-ventilated. Stagnant air can create a damp environment that’s attractive to ants.
- Regular Cleaning: Keep your cedar project clean and free of debris. This will help prevent ants from finding food sources nearby.
