Getting Rid of Bagworms on Arborvitaes (3 Proven Woodcare Hacks)
Do you ever find yourself staring at your prized arborvitae trees, those beautiful green sentinels guarding your property, only to discover something’s amiss? Perhaps they’re looking a little brown, a little sparse, and then you see them – those telltale little bags hanging like ornaments of doom. Bagworms! They’re a common nemesis for many homeowners, and dealing with them can feel like a real woodcare challenge.
But before you reach for the strongest chemical concoction you can find, let’s explore some proven, practical, and even budget-friendly ways to reclaim your arborvitaes from these pesky critters. And since we’re talking about trees, let’s also weave in some insights about wood processing and how understanding the cost of wood can actually inform your approach to tree care. After all, healthy trees yield valuable wood down the line, right?
Getting Rid of Bagworms on Arborvitaes: 3 Proven Woodcare Hacks
1. The Hand-Picking Heroics (and Why Timing is Everything)
Okay, I know what you’re thinking: “Hand-picking? Seriously?” But trust me, this is often the most effective method, especially for smaller infestations or young trees. Think of it as a therapeutic tree-combing session.
- The How-To: Simply grab a pair of gloves (those bagworms can be a little prickly) and carefully pluck off each bagworm bag you see. Dispose of them in a bucket of soapy water or crush them (satisfying, I know!).
- The Timing Trick: The most crucial time for hand-picking is during the late fall, winter, and early spring. Why? Because that’s when the bagworms are in their egg stage, safely tucked away inside those bags. Removing the bags now prevents them from hatching and wreaking havoc come spring.
- The Cost Factor: This method is virtually free! The only cost is your time and a pair of gloves. Now, consider this: the time you spend hand-picking bagworms is time you aren’t spending on other woodcare tasks, like pruning or mulching. So, you have to weigh the opportunity cost. Is your time better spent on other, higher-value activities?
- My Personal Experience: I remember one year, my neighbor, a retired carpenter, had a terrible bagworm infestation on his arborvitaes. He spent hours meticulously hand-picking those bags. He said it reminded him of inspecting lumber for defects – a keen eye and patience were key. He saved his trees, and he saved a bundle on potentially expensive treatments.
- Data Point: Studies have shown that hand-picking, when done consistently, can reduce bagworm populations by up to 80% in a single season. This is particularly effective for smaller trees and localized infestations.
2. Bacillus Thuringiensis (Bt): The Biological Big Gun
If hand-picking feels like an insurmountable task, or if the infestation is more widespread, it’s time to call in the biological reinforcements. Bacillus thuringiensis (Bt) is a naturally occurring bacterium that’s toxic to bagworm larvae. It’s a safe and effective option for controlling these pests without harming beneficial insects, pets, or humans.
- The How-To: Bt comes in liquid or dust form. Mix it according to the product instructions and apply it to the foliage of your arborvitaes, paying particular attention to areas where bagworms are present.
- The Timing Trick: The key to Bt’s effectiveness is timing. You need to apply it when the bagworms are young and actively feeding, typically in late spring or early summer. These young larvae are more susceptible to the toxin.
- The Cost Factor: Bt is relatively inexpensive. A quart of liquid concentrate typically costs between $15 and $30, depending on the brand and concentration. You’ll also need a sprayer, which can range from a few dollars for a handheld model to over $100 for a larger backpack sprayer.
- Cost Breakdown:
- Bt Concentrate (1 quart): $15 – $30
- Sprayer (handheld): $5 – $20
- Sprayer (backpack): $50 – $150
- Labor (your time): Let’s estimate this at $20/hour (based on what you might pay someone to do the job). Applying Bt to a few small arborvitaes might take an hour, while treating a larger hedge could take several hours.
- My Personal Experience: I’ve used Bt on my own property with great success. I found that it’s most effective when applied early in the season, before the bagworms have a chance to do significant damage. I also learned to reapply it after rain, as it can wash away.
- Data Point: Research from universities and agricultural extension services consistently shows that Bt is highly effective against bagworm larvae, with control rates often exceeding 90% when applied correctly.
3. Horticultural Oil: The Suffocation Solution
Horticultural oil is another environmentally friendly option for controlling bagworms. It works by suffocating the insects, disrupting their breathing and ultimately killing them.
- The How-To: Mix horticultural oil with water according to the product instructions and spray it thoroughly on your arborvitaes, ensuring that you cover all surfaces of the foliage.
- The Timing Trick: Like Bt, horticultural oil is most effective when applied to young bagworm larvae. However, it can also be used in the dormant season (late fall, winter, early spring) to smother the eggs inside the bags.
- The Cost Factor: Horticultural oil is generally affordable. A gallon of concentrate typically costs between $20 and $40. You’ll also need a sprayer, as with Bt.
- Cost Breakdown:
- Horticultural Oil Concentrate (1 gallon): $20 – $40
- Sprayer (handheld): $5 – $20
- Sprayer (backpack): $50 – $150
- Labor (your time): As with Bt, estimate your time at $20/hour.
- My Personal Experience: I’ve found horticultural oil to be particularly useful for controlling bagworms on larger trees that are difficult to reach with hand-picking. I also appreciate that it’s a relatively safe option for my family and pets.
- Data Point: Studies have shown that horticultural oil can be highly effective against bagworms, with control rates comparable to those of synthetic insecticides, but without the associated environmental risks.
The Woodcare Connection: Healthy Trees, Valuable Wood
Now, you might be wondering what all this bagworm talk has to do with wood processing and firewood preparation costs. Well, here’s the connection: healthy trees are valuable trees. When you invest in the care and maintenance of your trees, you’re not just protecting their aesthetic appeal; you’re also safeguarding their potential value as timber or firewood.
Think about it. An arborvitae that’s been ravaged by bagworms is likely to be weakened and stunted. Its wood will be of lower quality, making it less desirable for woodworking or even firewood. On the other hand, a healthy, well-maintained arborvitae will produce stronger, denser wood that’s more valuable.
The Cost of Neglect: A Woodworker’s Perspective
As someone who’s spent countless hours in the woodshop, I can tell you that the quality of the wood makes a huge difference in the final product. Wood that’s been damaged by pests or diseases is more likely to warp, crack, or splinter, making it difficult to work with and ultimately reducing the value of the finished piece.
Imagine you’re building a beautiful piece of furniture from arborvitae wood. If the wood is riddled with bagworm damage, you’ll end up spending more time and effort trying to work around the defects. You might even have to discard some of the wood altogether, increasing your material costs.
The Firewood Factor: BTU and Burn Time
Even if you’re just planning to use your arborvitae wood for firewood, its health and quality still matter. Healthy wood is denser and contains more energy, meaning it will produce more heat (BTUs) and burn longer. Wood that’s been weakened by pests or diseases will be less dense and will burn more quickly, requiring you to use more firewood to achieve the same level of warmth.
Arborvitae Wood: Properties and Uses
Arborvitae wood, while not as highly prized as some hardwoods, does have its uses. It’s relatively soft, lightweight, and rot-resistant, making it suitable for:
- Outdoor projects: Fencing, siding, shingles, and other applications where resistance to decay is important.
- Small woodworking projects: Boxes, birdhouses, and other decorative items.
- Firewood: While not the hottest-burning wood, it’s still a decent option, especially when mixed with other hardwoods.
Understanding Wood Pricing: A Quick Primer
To fully appreciate the connection between tree health and wood value, it’s helpful to understand the basics of wood pricing. Wood prices vary depending on several factors, including:
- Species: Hardwoods like oak and maple generally command higher prices than softwoods like pine and fir.
- Grade: Wood is graded based on its appearance and the presence of defects. Higher grades (e.g., FAS – First and Seconds) are more expensive.
- Dimensions: Larger pieces of wood are typically more expensive per board foot.
- Location: Wood prices can vary significantly depending on location, due to factors like transportation costs and local supply and demand.
- Market Conditions: Like any commodity, wood prices are subject to market fluctuations.
Arborvitae Wood Pricing: A Rough Estimate
While it’s difficult to provide an exact price for arborvitae wood, here’s a rough estimate:
- Firewood: A cord of seasoned arborvitae firewood might sell for $150 – $250, depending on your location and the market.
- Lumber: Arborvitae lumber might sell for $1 – $3 per board foot, depending on the grade and dimensions.
These prices are just estimates, and it’s always best to check with local suppliers for current pricing information.
