Woodpeckers drilling into your fiber cement siding? It happens more often than you’d think. Here’s why they do it, how vulnerable your siding really is, and what to do about it.
Here’s a question that catches most homeowners off guard: can woodpeckers damage fiber cement siding?
The short answer is yes — but before you panic, the longer answer is that it’s far less common than woodpecker damage to wood siding, and when it does happen, there’s almost always a specific reason behind it. Fiber cement products like James Hardie siding are engineered to be dense, hard, and pest-resistant. Woodpeckers strongly prefer softer materials where drilling is easier and more productive.
So why do some homeowners in Alabama and the Florida Panhandle wake up to find neat little holes in their fiber cement siding? And what can you do to stop it? Let’s dig in — starting with a closer look at the culprit.
Family Picidae — 23 species found in North America
Foraging for Insects The #1 reason. Woodpeckers hear insect larvae moving inside walls and drill to reach them. If carpenter ants, termites, or wood-boring beetles have colonized the area behind your siding, woodpeckers will find them.
Territorial Drumming Males drum on resonant surfaces to establish territory and attract mates. They prefer materials that produce the loudest sound — metal flashing, hollow wood, and sometimes fiber cement panels that resonate against wall cavities.
Creating Nest Cavities Some species excavate nesting holes in spring. They typically target soft, decaying wood — but a determined Pileated woodpecker (the largest common species) can excavate surprisingly hard materials.
Woodpecker Damage Risk by Siding Type
Not all siding materials are equally attractive to woodpeckers. The vulnerability depends on material hardness, resonance (how loud it sounds when struck), and whether insects can inhabit the space behind it.
Wood siding is by far the most vulnerable — soft enough for easy drilling, a natural habitat for insects, and resonant for territorial drumming. Vinyl siding falls in the middle: woodpeckers can punch through it, but it doesn’t attract them the way wood does. Fiber cement siding is significantly harder and denser, making it unpleasant to drill. Metal siding is nearly impervious to damage but is occasionally targeted for drumming because of the loud resonance (though the birds can’t penetrate it).
Fiber cement siding like James Hardie is one of the most woodpecker-resistant siding options available. When woodpeckers do target fiber cement, it’s almost always because insects have colonized the wall cavity behind the siding — not because the birds are attracted to the siding material itself.
Why Woodpeckers Sometimes Target Fiber Cement Siding
If fiber cement is so hard, why do some homeowners still see woodpecker damage? The answer almost always comes down to one of three scenarios.
1. Insect Infestation Behind the Siding
This is the big one. Woodpeckers have extraordinary hearing — they can detect larvae moving inside wall cavities. If carpenter ants, termites, or wood-boring beetles have established a colony in the sheathing behind your fiber cement siding, woodpeckers will drill through to reach them. In this case, the woodpecker is actually doing you a favor by alerting you to a pest problem you didn’t know about.
In North Alabama and the Gulf Coast, warm and humid conditions create ideal environments for carpenter ants and termites. Homes near wooded areas are particularly susceptible.
2. Territorial Drumming on Resonant Panels
Sometimes the damage isn’t foraging — it’s communication. If a fiber cement panel sits over a hollow wall cavity with minimal insulation, it can produce a resonant sound when struck. Male woodpeckers use this acoustic property to broadcast their territorial claims. The resulting damage tends to be shallow and spread across a wider area, rather than the deep, focused holes characteristic of insect foraging.
3. Nesting Attempts in Spring
During nesting season (typically March through June in the Southeast), woodpeckers may attempt to excavate cavities in any material they perceive as suitable. Fiber cement is hard enough to discourage most species, but the Pileated woodpecker — which is common throughout Alabama and the Florida Panhandle — is large and powerful enough to do real damage. These are the birds that excavate large rectangular or oval holes in trees, and they can apply that same force to your home.
How to Prevent Woodpecker Damage to Your Siding
Because all woodpeckers are federally protected under the Migratory Bird Treaty Act, you cannot trap, harm, or kill them. That means prevention is your only legal option — and fortunately, there are effective strategies that work without harming the birds.
Reflective tape, holographic bird scare strips, or predator decoys (owl or hawk models) mounted near problem areas can deter woodpeckers. Move decoys regularly — woodpeckers are smart enough to recognize stationary fakes within days. Reflective Mylar streamers that move in the wind are particularly effective.
Ultrasonic bird deterrent devices or wind chimes near affected areas can disrupt pecking behavior. Electronic deterrents that emit woodpecker distress calls or predator calls are the most effective sound-based option, though they may annoy neighbors.
Bird netting or hardware cloth mounted 3–4 inches away from the siding surface creates a physical barrier woodpeckers can’t get past. This is the most reliable method for persistent birds, especially during nesting season. It’s not the prettiest solution, but it works when nothing else does.
If woodpeckers are targeting a specific area, have a pest control professional inspect for insects in the wall cavity. Eliminating the food source often eliminates the woodpecker problem entirely. This is especially important in humid Southeast climates where carpenter ants and termites thrive year-round.
Existing holes attract more pecking — both from the original bird returning and from other woodpeckers investigating. Fill small holes with exterior-grade wood filler or fiber cement patching compound, then paint to match. For larger holes or damaged panels, professional repair and replacement is the better route. Seal all gaps around utility penetrations, soffit joints, and window frames where insects can enter wall cavities.
The most effective approach combines two or three of these strategies. Visual deterrents plus pest control, for example, addresses both the immediate behavior and the underlying cause. No single method works 100% of the time, because woodpeckers are persistent and adaptable.

When to Call a Siding Professional
Minor woodpecker damage — a few small, shallow holes — is usually a straightforward DIY fix with patching compound and paint. But there are situations where professional assessment and repair make more sense.
Call a Pro If You See:
- Multiple holes in the same area — This strongly suggests an insect colony in the wall cavity. Patching the holes without addressing the infestation means the woodpecker (or another one) will be back. A siding professional can remove panels to inspect the sheathing and coordinate with pest control.
- Large or deep holes — Holes larger than a quarter or deep enough to expose the wall sheathing compromise the siding’s moisture barrier. Water infiltration behind fiber cement siding leads to rot, mold, and structural damage that’s far more expensive than the repair itself.
- Damage near windows, doors, or utility penetrations — These areas are already vulnerable to water intrusion. Woodpecker holes near flashing, caulk joints, or utility boxes need professional sealing to maintain the building envelope.
- Cracked or broken fiber cement panels — Woodpecker impacts can crack fiber cement, especially older panels or panels with existing hairline fractures. Cracked panels need full replacement, not just patching, to maintain structural integrity and moisture protection.
- Recurring damage after DIY repairs — If you’ve patched holes and the bird keeps coming back, there’s an underlying attractant you haven’t addressed. A professional can diagnose the root cause — whether it’s insects, resonance issues, or a nesting preference — and implement a lasting solution.

Frequently Asked Questions
Yes, but it’s uncommon. Fiber cement is significantly harder and denser than wood or vinyl, making it difficult for woodpeckers to drill. Most species give up and move to an easier surface. The exception is the Pileated woodpecker, which is powerful enough to damage fiber cement — especially when motivated by insects in the wall cavity. In most cases, woodpecker damage to fiber cement is shallow surface pecking rather than full penetration.
No. All woodpecker species are protected under the federal Migratory Bird Treaty Act. Killing, trapping, or harming them without a depredation permit from the U.S. Fish & Wildlife Service is illegal and carries fines up to $15,000. In rare cases where non-lethal deterrents have failed, you can apply for a permit through your local USDA Wildlife Services office, but approval requires documented evidence of significant property damage and failed deterrent efforts.
Generally, no. Most homeowners insurance policies classify woodpecker damage as pest or vermin damage, which is excluded from standard coverage. Some policies may cover secondary damage — for example, if woodpecker holes allow water intrusion that damages your home’s interior. Check your policy language and contact your insurer to confirm. The best strategy is prevention: addressing the problem early before it requires extensive panel replacement.
