Chicago’s older neighborhoods — known for their classic brick homes, mature trees, and cozy attics — are among the most charming in the city. Unfortunately, these same features make them ideal for squirrel infestations. While squirrels may seem harmless, they can cause serious structural damage, fire risks, and sanitation problems. Here’s why squirrel control is vital for older Chicago homes and how you can protect your property.
Why Older Chicago Homes Attract Squirrels
- Mature trees and easy access
Tree-lined streets in areas like Lincoln Park, Ravenswood, and Hyde Park give squirrels easy routes from branches to rooftops. Overhanging limbs act as bridges to attics and vents. - Aging construction and hidden gaps
Decades-old homes often develop cracks, rotted fascia boards, or loose soffits. These small openings make perfect entry points for squirrels searching for warm nesting spots. - Complex rooflines and decorative trim
Dormers, eaves, and ornate detailing provide hidden nesting areas that make squirrel detection difficult — especially in historic homes. - Abundant nesting material
Attics filled with insulation and stored belongings give squirrels everything they need to build warm, hidden nests.
Damage Caused by Squirrels in Older Homes
- Chewed wiring and fire hazards: Squirrels gnaw on wires, posing a significant fire risk.
- Insulation damage: They tear and soil insulation, lowering energy efficiency.
- Structural wear: Persistent gnawing damages soffits, vents, and siding.
- Noise and odor issues: Scratching, droppings, and nesting materials create unpleasant smells and sleepless nights.
- Health concerns: Droppings and urine contaminate attic spaces and can attract fleas or mites.

Signs of a Squirrel Infestation
Watch for these early warning signs before the problem worsens:
- Scratching or running sounds, especially at dawn or dusk.
- Chewed roof vents, fascia boards, or insulation.
- Droppings or nesting debris in the attic.
- Squirrels entering and exiting holes near your roofline or chimney.
- Grease marks along the walls or eaves.
If you notice any of these, it’s time to consider professional squirrel removal in Chicago before the damage escalates.
Prevention Tips for Homeowners
Short-term fixes
- Trim tree branches at least 6–8 feet from your roof.
- Seal gaps larger than ½ inch with metal flashing or hardware cloth.
- Install chimney caps and secure attic vents.
- Use one-way exclusion devices to let squirrels exit but not re-enter.
Long-term solutions
- Schedule annual roofline and attic inspections.
- Replace damaged soffits and fascia immediately.
- Keep outdoor garbage sealed and remove easy food sources.
- Partner with a trusted wildlife control Chicago expert for ongoing maintenance.
DIY vs. Professional Squirrel Removal
DIY removal may seem tempting but often fails in older homes. Hidden entry points, tricky rooflines, and nesting young make complete removal difficult — and sealing too early can trap animals inside.
Professional squirrel control ensures:
- Thorough inspections of attics, vents, and eaves.
- Humane one-way exclusion and live removal.
- Full sanitation and attic cleanup.
- Repairs using chew-proof materials.
Typical Scenarios in Chicago’s Older Neighborhoods
- Bungalow attic infestation: A family in Irving Park heard scratching; technicians found a nest near chewed wiring — a serious fire hazard.
- Historic home in Edgewater: Squirrels entered through an unsealed chimney; exclusion devices and new chimney caps solved the issue permanently.
- Vintage two-flat: Entry through rotted fascia caused insulation contamination requiring cleanup and repairs.
Each case reinforces why ongoing squirrel control in Chicago is vital for safety and home preservation.
Prevention Checklist
Before winter hits, make sure you:
- Trim overhanging branches
- Inspect and seal attic openings
- Replace damaged soffits and vents
- Install chimney caps
Schedule a wildlife inspection every spring and fall
