You hear it again—that rhythmic tapping against your siding or under the eaves. Your first thought? Woodpecker. But before you start shopping for deterrents or setting up suet feeders to lure them elsewhere, it’s worth investigating what’s really making that noise. The culprit might surprise you.
Why That Tapping Might Not Be a Woodpecker After All

Real woodpecker drumming tends to follow a distinct pattern: rapid, rhythmic bursts that echo loudly, usually occurring in early morning during breeding season. They’re territorial birds, so the tapping is often concentrated in one spot and repeated over several days.
If your tapping doesn’t match that description, you’re likely dealing with something else. Random, irregular taps throughout the day and night point to different sources entirely. Pests moving inside walls create sporadic scratching and tapping. Plumbing systems produce metallic pings when water pressure shifts. Even your house itself generates sounds as building materials expand and contract with temperature changes.
Timing matters too. Woodpeckers are diurnal—they work during daylight hours and rest at night. Hearing taps after sunset? That’s almost certainly not a bird. Nocturnal sounds suggest rodents, insects, or mechanical issues. Pay attention to weather patterns as well. If tapping intensifies during temperature swings or windy conditions, you’re probably hearing your house respond to environmental changes rather than wildlife activity.
Pests and Critters Mimicking Bird Taps
Carpenter ants rank among the most common imposters. These industrious insects excavate galleries inside wood, and the process creates soft but audible tapping sounds, especially at night when your house is quiet. Unlike termites that work silently, carpenter ants are surprisingly noisy as they chew through structural wood. You might hear rustling alongside the tapping, and you’ll often find small piles of sawdust near baseboards or window frames.
Termites operate differently but can produce similar sounds. When disturbed, soldier termites bang their heads against tunnel walls to alert the colony—creating faint clicking or tapping noises. These sounds are subtle and easy to miss during daytime activity, but they become noticeable in the evening quiet. Both carpenter ants and termites prefer moist wood, so if you’ve had water damage or live in a humid climate, they’re prime suspects.
Rodents and squirrels create more chaotic soundscapes. Mice scurrying inside walls produce light, rapid tapping as their tiny claws hit wooden studs. Squirrels are heavier and louder, especially when they’re nesting in attics or soffits. Their movements sound like scratching combined with intermittent thumps. Squirrels are most active at dawn and dusk, so if your mysterious tapping follows that schedule, you’re likely hosting furry guests.
Bats present another possibility, though their sounds tend more toward squeaking and fluttering. Still, when roosting in tight spaces like behind shutters or under eaves, their movements can create tapping as they settle into position. The key difference? Bat activity corresponds with twilight hours, and you’ll typically hear them entering or exiting their roost rather than throughout the day.

Your plumbing system can be remarkably percussive. Water hammer—that sharp banging when you quickly turn off a faucet—occurs when rushing water suddenly stops and creates a pressure wave. The shock reverberates through pipes, producing loud taps or bangs that sound like someone knocking inside your walls. This happens most often with high water pressure or when pipes aren’t properly secured with mounting brackets.
Loose pipes amplify the problem. As water flows through unsecured sections, pipes can shift and tap against wall studs or floor joists. The sound varies with water usage—you might hear it when someone flushes a toilet, runs the dishwasher, or takes a shower. If your tapping correlates with plumbing use, that’s your answer right there.
Thermal expansion deserves serious consideration, especially in newer homes or those with metal components. As temperatures fluctuate between day and night, building materials expand when warm and contract when cool. Metal ductwork for heating and cooling systems is particularly vocal during this process. You’ll hear distinct pops, creaks, and taps as sheet metal flexes. These sounds typically occur during temperature transitions—early morning as things warm up, or evening as they cool down.
Wood framing does the same thing, though usually more quietly. In extreme temperature swings or during seasonal changes, wooden studs, joists, and rafters shift slightly. Nails gripping the wood can produce tapping or popping sounds. This is completely normal and generally harmless, though it can be startling if you’re not expecting it.
Wind introduces another variable. Loose siding, trim boards, or fascia can tap against the house structure when breezes pick up. Hanging gutters, downspouts, or exterior fixtures like light covers can also create rhythmic tapping as they move. Check your exterior on a breezy day to identify any components that might be making contact with the house.
Protecting Your Home and Backyard Birds
Start with a thorough inspection to identify the actual source. Walk your property during different times of day, listening carefully to pinpoint where sounds originate. Check for pest evidence like sawdust piles, droppings, or gnaw marks. Examine plumbing fixtures and listen near pipes when water is running. Look for loose exterior components that might move in wind.
If you discover pests, address them promptly but humanely. For rodents, seal entry points with steel wool and caulk—mice can squeeze through openings as small as a dime. Set live traps if needed, then release animals far from residential areas. For insects like carpenter ants or termites, consult a pest control professional. These require targeted treatment to prevent structural damage.
For plumbing issues, consider installing water hammer arrestors—small shock absorbers that cushion pressure waves. Secure loose pipes with foam padding and mounting brackets. If you’re uncomfortable with plumbing work, a licensed plumber can typically resolve these problems quickly.
Now, about those actual woodpeckers: if you confirm you do have them tapping on your house, they’re likely finding insects in your siding or drumming on resonant surfaces for territorial reasons. The solution isn’t to eliminate them, but to offer better alternatives. Install a suet feeder away from your house—woodpeckers love high-fat foods, especially during cold months. Add a dead snag or post to your yard where they can drum naturally without damaging structures.
Plant native trees and shrubs that support the insects woodpeckers eat. Oak, pine, and willow trees attract beetle larvae and other prey. Create a layered habitat with different vegetation heights. This benefits woodpeckers while supporting dozens of other bird species you’ll enjoy watching.
Consider visual deterrents if woodpeckers persist on your house. Reflective tape, pinwheels, or strategically placed netting can discourage them from problem areas without causing harm. Move these deterrents periodically so birds don’t become accustomed to them.
The tapping on your house tells a story—you just need to listen carefully to understand what it’s saying. Whether it’s tiny carpenter ants, expanding metal ducts, or an actual downy woodpecker, identifying the source lets you respond appropriately. Your home stays protected, and the birds in your yard get the habitat and food they truly need.
Happy birding—and happy investigating!
