How Wildlife Gets Into Your Home

You hear something in the attic at 2 a.m. Maybe it's a scratching sound above the bedroom ceiling. Maybe it's heavier, like a thud, a shuffle, something that clearly has four legs and zero business being up there. Whatever it is, one question immediately comes to mind: how did it get in?

It's a fair question, and one we get every day. Whether you're dealing with a raccoon that's made itself comfortable in your attic or a squirrel that's turned your soffit into a front door, the entry point is always step one. Knowing where wildlife gets in helps us get to the root of the problem and fix it for good, not just for now.

Common Home Entry Points for Wildlife

Here's a look at the most common entry points we see on homes in Noblesville and the surrounding communities, and which animals tend to use them.

The Roofline

If your home has a roofline, you have potential entry points. It's that simple. The roofline is where most wildlife access happens, and for good reason. it's elevated, often sheltered, and frequently overlooked during routine home maintenance.

Roof vents are one of the most common culprits.

These vents are often made of thin plastic or lightweight metal, and they don't put up much of a fight against a determined raccoon. Raccoons are strong and surprisingly dexterous. they can pull a vent cover clean off in a matter of minutes. Once inside, they head straight for the insulation, which makes excellent nesting material.

Soffits and fascia are another frequent entry point, particularly for squirrels and bats.

Squirrels will chew through rotting or compromised wood to create or expand an opening. Bats don't need much space at all, a gap as small as 3/8 of an inch is enough for a bat to squeeze through. They're often found entering at the point where the soffit meets the roofline, especially on older homes where materials have begun to separate or deteriorate.

Roof edges and damaged shingles 

Any place where the roofing material has lifted, cracked, or pulled away from the underlying structure is an invitation. Wildlife doesn't create damage out of nowhere, it exploits damage that's already there. That small area of missing flashing or the shingles that took a beating in last winter's ice storm? Worth a look.

Chimneys

An uncapped chimney is essentially a wildlife welcome mat. Raccoons in particular are drawn to chimneys because the enclosed, dark, elevated space mimics the hollow trees they naturally den in. A female raccoon looking for a place to have her young will find an open chimney and consider the problem solved.

Squirrels use chimneys too, though they're more likely to fall in accidentally and find themselves unable to get back out. Either way, the solution is the same: a properly fitted chimney cap. It's one of the simplest and most effective forms of wildlife exclusion there is.

Attic Vents and GABLE Vents

Beyond roof vents, gable vents (the vents on the triangular end walls of your attic) are a common access point for squirrels, bats, and birds. Older gable vents made of wood or thin screening can weaken over time, and squirrels will take full advantage of any gap or compromised material.

Attic turbine vents and ridge vents can also allow access if they're not properly secured or if screens have been damaged. Bats are especially skilled at finding these small vulnerabilities. A bat colony doesn't need a large opening, it needs a consistent one.

Foundation and Ground-Level Access

Not all wildlife comes in from the top. Opossums in particular tend to access homes from the ground up, taking advantage of gaps where the home meets its foundation, crawl space vents, or openings around utility lines and pipes.

Crawl space vents 

These are a major point of entry for opossums and other ground-level wildlife. These vents are often covered with thin screening that deteriorates over time, and an opossum won't hesitate to push through a vent that's lost its structural integrity.

Gaps around utility penetrations 

Anywhere gas lines, electrical conduits, or plumbing enter the home are often overlooked during construction or renovation and can leave surprisingly large openings that wildlife will find.

What to Do When You Suspect a Wildlife Entry Point

If you're hearing sounds, noticing damage, or spotting signs of wildlife activity around your home, the first step is to resist the urge to seal anything yourself. Here's why: if an animal is already inside when you close off the entry point, you've now trapped it...and that creates a much bigger, much messier problem. Young animals may be separated from a mother, or an animal may die inside the wall or attic.

The right move is to call a professional who can assess the situation, safely remove the animal, and then seal the entry point properly with materials and methods that actually hold up over time.

That's exactly what we do. One call handles the animal, the entry point, and any damage left behind, so your home looks and functions the way it did before wildlife ever became an issue. No repeat visits from us, and no repeat visits from them.

If you're in Noblesville or the surrounding area and something doesn't sound right in your walls or attic, give us a call. We'll figure out how it got in and make sure it can't happen again.
