Squirrels don’t look like much of a threat from the yard, but once they’re in an attic, they’re one of the more destructive wildlife problems a homeowner can deal with.

How They Get In
Squirrels are persistent. They chew constantly — their teeth never stop growing and have to be worn down. That means wiring, wood framing, roof sheathing, and insulation are all viable targets. The damage accumulates faster than most people realize, and by the time the scratching overhead becomes obvious, the repair scope is usually already significant.
They test gaps along the roofline, they gnaw at weak points in wood trim, and they’re motivated enough to create an opening if one isn’t already there. A gray squirrel needs about an inch and a half of clearance to get started — and it will widen that gap to whatever size it needs.
The entry points we find most often: soffit gaps where the panel has pulled away from the fascia, roof vent screens that have rusted or pulled loose, construction gaps along dormers and roof edges, and areas where trim has warped and separated. Overhanging tree branches are how they get to the roofline in the first place. A branch touching or hanging over the roof is a highway, not just a shade feature.
This is the part that isn’t about annoyance. Squirrels gnaw through electrical wiring insulation — partially or completely — and that damage doesn’t always fail immediately. It sits. Weeks or months later, it causes a short or a fire. Gnawed attic wiring is a documented cause of residential structure fires. It needs to be found and assessed, not just assumed to be minor.
Beyond wiring, flattened or contaminated insulation, gnawed structural members, and damaged HVAC components add repair costs that dwarf what the exclusion work itself costs.
Why Trapping Alone Doesn’t Work
What Doesn’t Work — and What Does
Setting traps in an attic without sealing the entry point removes the squirrel that’s there today. The next one uses the same gap within days. And if there’s an active nest with young inside, trapping the mother first creates a secondary problem — young in an inaccessible space with no way out.
We sequence this correctly: confirm activity, allow the existing animals to exit through a one-way device if needed, verify the space is clear, then seal every identified opening with hardware cloth and construction-grade fasteners. Not foam. Squirrels chew through foam.
Works – Permanent Exclusion
Hardware cloth — properly sized and properly secured — is the standard that holds. We use galvanized steel mesh with a small enough gauge that a squirrel can’t bite through or pry open. It gets fastened at the edges, not just stapled, because a loose edge is something a motivated squirrel will work at. We also close every secondary opening along the roofline, not just the one they’ve been using, because they’ll shift to the next weak point if given the chance.
One squirrel in the attic can cause thousands of dollars in damage. Call early.
Complete Rodent
Exclusion Services
Rodent problems don’t fix themselves—they get worse. Our complete exclusion services are built to remove infestations, repair the damage, and protect your home for the long term.
RATS
The most common call we get. Norway rats, roof rats — each behaves differently and requires knowledge of their habits to seal them out effectively. This is our specialty.
MICE
A mouse can squeeze through a gap smaller than a dime. Don’t underestimate a “small” mouse problem — a pair of mice can become a full infestation in a matter of weeks.
SQUIRRELS
Squirrels in an attic chew wiring, destroy insulation, and cause structural damage quickly. They’re persistent and need properly installed hardware cloth to keep out for good.
RACCOONS
Strong, intelligent, and capable of forcing through weak barriers. Raccoon exclusion requires heavier-gauge materials and careful attention to any opening large enough for them to exploit.
What We Inspect
Full Roofline and Exterior Inspection
We walk the entire roof and exterior perimeter — soffit, fascia, eaves, gable vents, dormers, and every utility penetration. Squirrels exploit construction gaps most inspectors never get close enough to see. We document every point of entry we find.
Attic Interior Assessment
We inspect the attic for active nesting, shredded insulation, gnawed wiring, and travel routes along joists and beams. We look for evidence of current occupancy and check for litters before any exclusion work begins.
Sealing Every Entry Point
Hardware cloth, galvanized steel mesh, metal flashing, and lumber — every identified opening gets sealed with materials squirrels cannot chew through or force past. If it’s a gap, it gets closed. If it’s a vent, it gets properly screened.
One-Way Exit and Mechanical Trap Placement
Any squirrels still inside need a way out before we seal completely. We use one-way exclusion devices at active entry points and place mechanical snap traps in the attic to catch what remains. No poison — ever.
Squirrel-Free Declaration
When the attic is clear and every entry point is sealed, we declare the property squirrel-free. Your guarantee starts from this point.

What
We Use
Construction-Grade Materials Only
Hardware Cloth — The Primary Barrier
Galvanized steel mesh with a tight enough gauge that squirrels cannot bite through or pry open. We use it on soffits, gable vents, crawl space openings, and any gap where the opening is larger than a half-inch. Properly fastened at every edge — not stapled, secured.
Solid Metal Flashing
Used along rooflines, fascia boards, and anywhere sheet-metal coverage is the right call. Squirrels can gnaw wood indefinitely — they cannot gnaw through properly installed flashing. Durable, weatherproof, and built for the roofline environment.
Concrete & Quick-Set
For foundation gaps and masonry penetrations. When it hardens, it’s done. Squirrels that find a concrete-filled gap move on — there’s nothing to work with.
Lumber and Solid Blocking
For structural gaps under eaves, along garage thresholds, and in framed openings that need solid infill. Done properly, it blends with the existing roofline and is far more durable than any screen-only solution.
Never Spray Foam
We don’t touch it. Squirrels chew through foam in minutes. Any company using spray foam as a squirrel barrier either doesn’t know better — or doesn’t care. We know better.
