If you have noticed a woodpecker hammering away at a tree in your yard, you are probably wondering two things: why is it doing that, and is it hurting my tree? The pecking can be loud, persistent, and alarming, especially when you start seeing holes in the bark. The good news is that woodpeckers rarely kill healthy trees. The more important news is that heavy woodpecker activity is often a signal that something else is going on with the tree, and that signal is worth paying attention to.
Here is what woodpecker pecking actually means and when it is worth calling a professional.
Why Woodpeckers Peck Trees
Woodpeckers peck for several distinct reasons, and understanding which one you are dealing with tells you how concerned to be.
Searching for food is the most common reason. Most woodpeckers eat insects that live in or under tree bark, including carpenter ants, wood-boring beetles, and larvae. When a woodpecker is drilling into a tree to feed, it is going after bugs that are already inside the wood.
Feeding on sap is specific to sapsuckers, a type of woodpecker that drills neat, orderly rows of small holes to feed on the sap that flows out. The sap also attracts insects, which the sapsucker eats when it returns.
Nesting is another reason. Woodpeckers excavate cavities in trees, usually in soft, dead, or decaying wood, to build nests.
Drumming is communication, not feeding. In spring especially, woodpeckers rapidly tap on resonant surfaces, including trees, gutters, and siding, to attract mates and mark territory. Drumming does not damage the tree.
Do Woodpeckers Actually Damage or Kill Trees?
For a healthy tree, the answer is almost always no. The holes a woodpecker makes while feeding or drumming are typically superficial, and a healthy tree easily withstands them. In most cases, woodpecker activity is more of an annoyance than a genuine threat.
There are two exceptions worth knowing about:
The first is girdling: In rare cases, a woodpecker, usually a sapsucker, drills holes in a ring all the way around the trunk or a branch. If that ring is complete, it can interrupt the flow of water and nutrients and kill the portion of the tree above the damage. This is uncommon but serious when it happens.
The second is repeated sapsucker damage: Sapsuckers often return to the same tree again and again. Over time, heavy, repeated drilling can weaken the tree and create many small wounds that become entry points for disease and further insect activity.
But here is the most important point, and the one most homeowners miss.
Woodpecker Activity Is Often a Warning Sign
Woodpeckers do not peck randomly. They concentrate on trees that already have insects in the wood. So when a woodpecker is working hard on a particular tree, it is frequently telling you that the tree has an underlying pest problem, and often that the tree is already stressed, declining, or partially decayed.
In other words, the woodpecker is usually a symptom, not the cause. The real issue is often what the woodpecker is eating: carpenter ants, wood-boring beetles, or borers that infest stressed and dying wood. In Northern Virginia, that can include serious pests like the emerald ash borer, which we cover in our guide on dead and diseased tree removal.
This is why persistent woodpecker attention on one tree is worth investigating. The bird may be pointing you to an infestation or a section of dead, decaying wood you did not know was there.
Signs the Tree, Not the Woodpecker, Is the Problem
Look for these indicators that the tree already has an underlying issue:
- The woodpecker keeps returning to the same tree or the same spot
- You see sawdust or fine wood shavings at the base of the tree
- The bark has other exit holes, tunnels, or cracking
- There are dead or dying branches in the canopy
- The wood in the pecked area looks soft, punky, or decayed
- You notice insects, especially ants, moving on the trunk
If you see these signs alongside woodpecker activity, the tree is worth a professional assessment. Our guide on how to recognize a dead or diseased tree can help you identify what to look for.
What to Do About Woodpecker Damage
If the tree is healthy and the pecking is light, you generally do not need to do anything. The tree will be fine, and woodpeckers are protected under federal law, so harming them is not an option anyway.
If a sapsucker is causing repeated damage to a valued tree, wrapping the affected area with burlap or hardware cloth during peak activity can discourage return visits without harming the bird. Keeping trees healthy and well-maintained also makes them less attractive, since woodpeckers prefer stressed and insect-infested wood.
If the woodpecker activity is a sign of an underlying infestation or decay, the right move is to address the tree itself. That may mean treating a pest problem, pruning out dead or infested wood, or, if the tree is significantly declined, removing it before it becomes a hazard.
When to Call a Professional
Consider a professional assessment when a woodpecker is repeatedly targeting the same tree, when you see the warning signs of infestation or decay listed above, when there are dead branches over your home or high-use areas, or when you are simply not sure whether the tree is healthy. A tree service can determine whether the tree has a pest or disease problem, whether it can be treated or pruned, and whether removal is warranted.
Frequently Asked Questions About Woodpeckers and Trees
Woodpeckers peck to find and eat insects living in the wood, to feed on sap, to excavate nesting cavities, and to drum as a way of communicating with other woodpeckers during mating season. Feeding on insects is the most common reason, and it usually means the tree already has bugs in it.
Rarely. Healthy trees easily withstand normal woodpecker activity, and the damage is usually superficial. The exceptions are girdling, where holes ring the trunk completely and cut off the flow of nutrients, and repeated heavy sapsucker damage, which can weaken a tree over time and open it to disease.
Sometimes. The holes themselves are usually harmless, but woodpeckers target trees that already contain insects. Persistent woodpecker activity on one tree can indicate an underlying pest infestation or areas of dead, decaying wood, so it is worth investigating what is attracting the bird.
For valued trees suffering repeated sapsucker damage, wrapping the affected area with burlap or hardware cloth during peak activity can deter return visits without harming the bird. Keeping trees healthy also helps, since woodpeckers prefer stressed and infested wood. Woodpeckers are federally protected, so any deterrent must be non-harmful.
Not necessarily. If the tree is healthy, no. But if the woodpecker activity points to a serious infestation, extensive decay, or a tree that is already declining and poses a hazard, removal may be the right call. A professional assessment is the best way to decide.
