You may love watching birds in your yard, but you don’t want them moving into your house. When temperatures drop or food becomes harder to find, birds start looking for safe places to build nests. Many of those places end up being inside homes.

So, where are the most common places birds nest in a house? The answer is simple: anywhere warm, hidden, and protected from predators. These are the common bird nesting spots that birds love most. You’ll often see them in vents, attics, gutters, or even under roof shingles. Once inside, they can be hard to move and may cause health or safety risks.

At Skedaddle Humane Wildlife Control in Anoka County, we’ve seen birds nesting in homes across Anoka and surrounding areas. We know where they hide, why they pick those spots, and what it takes to keep them out. This article will walk you through the most common nesting places, the problems they create, and why preventing bird nests indoors is so important.

Why Birds Nest Inside Homes

Birds are just trying to survive. They want warmth, food nearby, and shelter from predators. A house offers all of that, often better than nature. When they can’t find a hollow tree, they turn to chimneys, vents, or attics.

The issue is that once they move in, the problems start:

• Nests can block airflow and create fire risks.
• Droppings spread disease and damage surfaces.
• Noise and scratching disturb your family’s peace.
• Parasites from birds can spread indoors.

Now let’s look at the most common bird nesting spots you should know about.

Attics and Lofts

Attics are a favorite nesting site. They’re warm, dark, and rarely disturbed. Birds can slip inside through roof vents, loose shingles, or gaps along the eaves. Once inside, insulation makes the perfect material to build a nest.

Key reasons attics attract birds:

• Vents, cracks, and roof gaps act like open doors.
• Quiet, undisturbed spaces are safe for raising young.
• Insulation provides warmth and nesting material.
• Easy access to food outdoors makes the attic a handy base.

Left unchecked, nests in attics can damage insulation, wiring, and wood framing.

Vents

Dryer vents, bathroom vents, and kitchen exhaust vents are another favorite. The air blowing out provides warmth, and the tunnel-like space is perfect for nests. Birds often squeeze past flimsy vent covers or damaged screens.

The problem is that nests in vents can block airflow, which is unsafe. A clogged dryer vent, for example, increases the risk of fire. Families in Anoka have reported smoke backing up into the house or strange smells when nests are hidden in vents. This is one of the most common places we find birds nesting in homes.

Chimneys

Chimneys act like hollow trees, which makes them very appealing to birds. Species like chimney swifts are even named after their habit of nesting inside. Once inside, they build twig nests that cling to the chimney walls.

Blocked chimneys are dangerous because they can trap smoke and carbon monoxide inside your home. Birds nesting here also drop feathers and debris, which may fall into the fireplace. If you use your fireplace in winter, this creates serious risks. Preventing bird nests indoors often starts with making sure chimneys are protected.

Gutters and Eaves

The edges of roofs give birds shelter from rain and wind. When they build under eaves or inside gutters, nests often go unnoticed until water backs up or droppings pile up.

Problems caused by nesting here:

• Blocked gutters lead to roof leaks.
• Droppings damage siding and paint.
• Constant chirping near bedrooms can disturb sleep.

This is one of the most common bird nesting spots because it’s easy to access and close to outdoor food sources.

Vents and Exhaust Fans

Any vent leading outside can be a target. Dryer vents, bathroom fans, and kitchen exhaust systems all pull in warm air, which attracts birds.

What makes vents risky:

• Birds bring in twigs, straw, and feathers that clog airflow.
• Heat from appliances can spark fires if nests are too close.
• You may hear scratching or fluttering sounds in the walls.

Even a small vent can hide a surprisingly large nest.

Roof Shingles

Loose shingles are another hidden place where birds try to nest. The small gaps offer protection from wind and rain, and once a bird squeezes in, it often pulls in straw, leaves, and twigs to build a home.

While it may seem harmless at first, nesting under shingles can damage your roof. Moisture builds up, shingles loosen further, and leaks may form. Over time, this can lead to costly repairs. Homeowners in Anoka are often surprised to find that birds nesting in homes start with something as small as a cracked shingle.

Garages and Sheds

Birds are resourceful and will take any chance they get to enter spaces like garages or sheds. Open doors, broken windows, or vents make it easy for them to slip inside. Once in, they’ll often nest on beams, shelves, or storage boxes.

The mess left behind can be frustrating. Droppings collect on tools, cars, or stored items. In colder months, nests inside garages or sheds can also attract mice looking for warmth. Preventing bird nests indoors means paying attention to these overlooked areas, not just the main house.

Porches and Decks

Covered porches and decks create sheltered spaces perfect for nests. Birds tuck themselves into corners, beams, or decorative features. Some even nest in hanging planters if they’re left outside year-round.

While it might seem charming, porch nests can cause problems. Droppings stain wood and furniture, and aggressive parent birds may dive at people walking nearby. It’s a common issue in Anoka neighborhoods where porches are used daily.

Window Ledges and Light Fixtures

Flat surfaces around windows or light fixtures seem harmless, but they’re often nesting spots too. Birds use these areas because they’re stable and close to buildings.

Risks include:

• Droppings staining walls, windows, and porches.
• Feathers and straw falling onto walkways.
• Aggressive behavior if you get too close during nesting season.

Though they seem minor, these nests can still create safety and cleanup issues.

Basements and Crawl Spaces

Not all nesting happens above ground. Basements and crawl spaces provide dark, protected areas where birds may sneak in through foundation cracks or vents.

Why these areas matter:

• Constant darkness makes birds feel safe.
• Easy entry points through small openings.
• Droppings can mix with dampness, creating mold risks.

This is less common than chimneys or attics, but still possible, especially in older homes.

The Risks of Indoor Bird Nests

Birds may seem harmless, but their nests can cause issues you might not expect:

• Health Problems: Droppings carry bacteria, fungi, and parasites. Breathing dust from droppings may trigger respiratory issues.
• Fire Hazards: Nests in vents, chimneys, or near wires are flammable.
• Property Damage: Roofs, gutters, and siding can all be damaged by nesting.
• Noise: Constant chirping, scratching, or flapping becomes stressful over time.
• Blocked Airflow: Nesting in vents or chimneys can keep smoke, heat, or moisture from moving safely through your home.
• Pests: Nests often bring mites, insects, and other small animals inside with them.
• Unpleasant Odors: Droppings and decaying nesting material create strong smells that spread through the house.

These risks grow if nests are left alone. That’s why professional help is needed to keep birds out safely.
