That early-morning scratching overhead isn’t your imagination. If you’ve been hearing scampering in the ceiling around dawn, or watching squirrels run the rooflines and disappear near the eaves, there’s a strong chance one has set up a nursery in your attic. Summer is a prime breeding window for gray squirrels in Southwest Florida, which makes July one of the busiest months of the year for squirrel calls in Manatee and Sarasota counties.
Here’s why it happens now, what it costs you if you ignore it, and why the timing of the removal matters more than most homeowners realize.
Why Squirrels Move In During Summer
The eastern gray squirrel (Sciurus carolinensis) is one of the most common nuisance animals in Florida and breeds roughly twice a year, with one of those breeding periods falling in late spring and summer.[^1][^2] Litters typically run one to four young, and juveniles stay in the nest for several weeks before they’re mobile.[^2]
When a female is ready to give birth, she wants a spot that’s warm, dry, hidden, and defensible. Your attic checks every box. Roofline gaps, fascia corners, soffit returns, and vents all offer easy access, and once she’s inside, she’ll build a nest (called a drey) out of leaves, twigs, insulation, and whatever else she can shred.[^3] That’s how a quiet summer afternoon turns into months of activity directly above your living space.
Gray squirrels are also remarkably good at getting in. They’re agile climbers that can squeeze through openings as small as about 1.5 inches — roughly the size of a golf ball — and reach roofs, walls, soffits, and vents with ease.[^3]
The Damage Adds Up Fast
It’s tempting to think of squirrels as harmless backyard entertainment. Inside an attic, though, they’re a destructive rodent, and the bill grows the longer they stay.
A squirrel’s incisors never stop growing, so it has to gnaw constantly to keep them worn down.[^3] In an attic, that chewing lands on framing, wood trim, PVC pipe, air ducts — and electrical wiring. Chewed wiring is the most serious risk, because exposed wires inside a wall or attic are a recognized fire hazard.[^4] On top of the structural damage, squirrels trample and tunnel through insulation, which reduces its effectiveness, and they leave droppings and urine that create odor and contamination problems over time.[^5]
Other signs of an infestation include:
- Scratching or scampering at dawn and dusk, when squirrels leave to forage and return to the nest.[^6]
- Gnaw marks on wood, wiring, ducts, or pipes in the attic.[^6]
- Small tracks in the dust along ducts and beams.[^6]
- Droppings and trails tunneled through attic insulation.[^5]
Why You Can’t Just Seal the Hole
This is the part that trips up well-meaning homeowners every summer: if there are babies in the nest, sealing the entry point is the worst thing you can do.
During the breeding season, a mother squirrel is highly motivated to defend her young and return to the nest. If you close her out while pups are still inside, you trap the babies, which leads to a dead-animal problem, terrible odor, and a frantic mother who will chew her way back in — often creating more damage than the original entry point.[^7]
The professional approach is sequenced for exactly this reason. You confirm whether young are present, remove the squirrels humanely (mother and pups together), and only then seal the home so they can’t return.[^7] Getting that order wrong is what turns a manageable problem into an expensive one.
How Wildlife Trapper Handles Squirrels
At Wildlife Trapper, squirrel removal isn’t just trapping — it’s a complete solution built around the season you’re in. Our process across the Bradenton, Lakewood Ranch, Sarasota, and Parrish area looks like this:
- Inspection. We locate the entry points, confirm whether a nest with young is present, and map out how the squirrels are moving through the structure.
- Humane removal. We remove the animals using humane methods, with special care during litter season to keep mothers and pups together and avoid trapping babies behind a sealed wall.
- Exclusion. Once the attic is clear, we seal the roofline gaps, soffits, vents, and other openings so squirrels can’t get back in. This step is what actually solves the problem long-term.
- Cleanup and restoration. We address the contaminated nesting area, soiled insulation, and droppings so your attic is safe and sanitary again.
We’re a licensed, insured, family-owned company with more than 20 years in the region, and we work without poisons or harsh chemicals.
Keep Squirrels Out for Good
After removal, a few habits help keep your attic squirrel-free:
- Trim back branches that overhang or touch the roof — they’re the squirrel highway onto your house.
- Keep bird feeders away from the structure, since feeders quickly become squirrel feeders and concentrate activity near the home.[^3]
- Inspect the roofline seasonally for new gaps at soffits, fascia, vents, and where utilities enter.
- Address small openings immediately — a golf-ball-sized gap is all it takes.[^3]
- Don’t wait between breeding seasons. Squirrels breed more than once a year, so an entry point left open after one litter often invites the next.[^7]
When To Call
If you’re hearing daytime activity overhead, finding gnaw marks or droppings in the attic, or watching squirrels repeatedly enter the same spot on your roofline, summer is the time to act — before the current litter matures and the problem doubles.
