You hear it in the morning: a faint scraping above the ceiling, then what sounds like footsteps moving across the attic floor. By midday it stops, and by evening you have almost convinced yourself it was nothing. That sound is worth paying attention to.
Squirrels in an attic do not leave on their own, and the longer they stay, the more they chew, nest, and contaminate the space. If you are dealing with squirrel removal in your Destrehan attic, this guide covers how the process works, what is at risk, and what to do next.
Key Takeaways
- Squirrel removal from an attic involves inspection, trapping or exclusion, and sealing every entry point; skip any one step and the problem comes back.
- Sealing entry points before confirming pups are gone can trap young squirrels inside and turn a manageable problem into a larger one.
- Daytime scratching, chewed vent covers, or disturbed insulation are the first signs something has moved in overhead.
- Gray squirrels produce a second litter in June or July, so summer is a common window for new attic intrusions in southern Louisiana.
How Squirrel Removal from an Attic Works
Getting squirrels out of an attic is a multi-step process. Trapping alone is not enough. If entry points stay open, new animals move in to replace the ones removed. Each step builds on the last: find every way they are getting in, remove the animals, then close off access permanently.
Inspection First
The job starts with a full property inspection: attic interior, roofline, soffits, vents, and fascia. A technician looks for active nesting, signs of young, and every opening squirrels are using to get in and out. Skipping this step is the most common reason DIY attempts fail. Entry points that look minor from the ground are often the primary access route.
Removal and Exclusion
Once the inspection is complete, removal typically involves trapping and exclusion methods, depending on whether young are present. One-way doors let squirrels exit but block re-entry, and they are the preferred method when a litter is still inside. Trapping is used when the timing is appropriate, and the attic can be confirmed to be clear. A professional squirrel and wildlife removal service covers both approaches, with state-permitted technicians building a plan based on what the inspection finds.
Sealing Entry Points
After the animals are out, every opening a quarter-inch or larger gets sealed with durable, chew-resistant materials. This is the step that makes removal last.
Signs You Have Squirrels in Your Attic
Squirrels are active during the day, which makes them easier to detect than nocturnal animals like rats or flying squirrels. Noise, physical damage, and debris each tell part of the story, and most homeowners have already noticed at least one before they call.
What to Listen For
The most reliable indicator is daytime sound: scratching, scurrying, or thumping from above, particularly in the early morning or late afternoon when squirrels are most active. The movement tends to sound purposeful and repetitive, following the same path across the attic floor. If the noise stops around midday and resumes later, that rhythm is a consistent sign.
What to Look For
Outside the home, check the roofline for chewed soffit edges, cracked or bitten plastic vent covers, and raw wood where trim has been gnawed. Inside the attic, look for shredded insulation pulled into piles, strips of bark or leaves brought in for nesting, droppings, and nutshell fragments tucked between joists. Squirrels cache food near their nesting sites, and finding acorn shells or debris between joists often confirms an animal has been present for some time.
One Sign Homeowners Often Miss
Unexplained electrical issues, such as flickering lights or a tripped breaker, can sometimes trace back to chewed wiring in the attic. It is worth checking for other signs of animal activity before calling an electrician first.
Why This Happens in Summer in Destrehan
Squirrel activity in attics peaks during summer for a specific reason, and knowing it helps homeowners catch the problem earlier.
According to the LSU AgCenter, gray squirrels in Louisiana breed during two distinct periods: mid-December to early January, and again in June, with a gestation period of around 43 days. That puts the second litter in July or August. By mid-to-late summer, those pups are weaned and beginning to move on their own, which means activity inside an infested attic grows louder as the season continues, not quieter. Attic dens can shelter several gray squirrels at once, and young typically begin leaving the nest around 10 to 12 weeks of age.
Destrehan sits along the River Road corridor in St. Charles Parish, surrounded by mature hardwood canopy that sustains large gray squirrel populations. Branches that extend over a roofline give squirrels a direct path to soffits, ridge vents, and fascia edges. An attic offers what a tree cavity does: dry shelter away from predators and weather. Once squirrels find a gap, they use it repeatedly, and the same entry points are reused season after season if they are not sealed.
What Squirrels Damage While They Are Up There
Squirrels cause more structural damage than most homeowners expect. As rodents, their front teeth grow continuously, which means they gnaw constantly to keep their incisors filed down on whatever material is available.
Wiring and Fire Risk
Electrical wiring gets stripped of its insulation covering, which can expose live conductors against wood, paper-backed insulation, or dry nesting debris. Damaged wiring is a fire hazard and can also produce intermittent power problems that do not trace back to an obvious cause.
Insulation and Energy Loss
Attic insulation gets torn apart for nesting material, displaced, and contaminated with urine and droppings. Once damaged or compressed, it loses thermal resistance. In a Louisiana summer, that loss shows up in how hard the HVAC system works and how much the utility bill climbs before a homeowner connects the two.
Wood, Water, and Odor
Rafters, roof decking, and wood trim around entry points take ongoing gnawing damage over time. The holes squirrels use to get in can also let water inside during rain events, which leads to wood rot and moisture problems that compound the original repair cost. Accumulated droppings, urine, and nesting material create odor problems that can reach living areas below, and moisture-laden debris left in the attic can encourage mold growth if left long enough.
Why Timing the Removal Correctly Matters
Not every squirrel removal job can follow the same schedule. The presence of young squirrels changes what methods are appropriate and what happens when someone moves too fast.
The Risk of Sealing Too Early
One of the most common mistakes homeowners make is sealing entry points before confirming whether young are still inside. A nesting female in June or July likely has pups that cannot yet leave on their own. Seal the attic while they are still inside and two things happen: the pups die inside the structure, creating an odor problem, and the mother works to chew back through, sometimes opening new entry points in the process.
Working Within Louisiana’s Rules
In Louisiana, wildlife control operators must hold a valid NWCO permit issued by the Louisiana Department of Wildlife and Fisheries and must pass a state examination covering wildlife biology, control methods, and regulations before working legally.
Squirrel Removal in Attic: Bottom Line
A squirrel in the attic is not a problem that resolves itself. Wiring gets chewed, insulation gets torn apart, water finds its way in through the entry holes, and by the time the smell reaches the living space, the damage has been building for weeks. Summer litters mean the population grows quickly if nothing is done.
Sealing entry points without a proper inspection, or without confirming no young are inside, creates a second problem on top of the first. The right move is an inspection that identifies what is present, where animals are getting in, and what removal and exclusion will take.

Frequently Asked Questions
How do I know if the sounds in my attic are squirrels and not rats?
Squirrels are active during daylight hours, with early morning and late afternoon being the busiest windows. Rats are primarily nocturnal, so daytime scurrying and scratching points more strongly toward squirrels. Squirrel movement also tends to sound heavier and more deliberate. A professional inspection can confirm which animal is present.
Is it safe to seal my attic once the noise stops?
Not without confirming the space is clear first. If a female had a litter in June or July, pups may still be inside even after things go quiet. Sealing entry points prematurely traps young inside. A permitted technician can verify the attic is clear and use one-way exclusion methods when the timing is right.
What entry points do squirrels typically use on Destrehan homes?
The most common access points are damaged or missing soffit panels, cracked attic vent covers, and gaps where the fascia meets the roofline. Overhanging branches that scrape or loosen roofing materials over time create entry opportunities as well. Squirrels can fit through small openings, so gaps that look minor from the ground are often enough.
Will squirrels come back after removal?
They can if entry points are not properly sealed. Physical exclusion with chew-resistant materials is what makes removal last. LaJaunie’s backs wildlife exclusion work with a one-year warranty.
