Raccoons in the Home
Signs of an Active Raccoon Presence
To determine if a raccoon has babies in your attic, listen for high-pitched, bird-like chittering or crying, typically between 10 PM and 4 AM. Watch for a mother raccoon entering and leaving the attic multiple times a day to forage, and check the attic for shredded insulation and a foul odor.
- Distinct Vocalizations: Baby raccoons are very noisy and make a continuous, complex mix of chittering, squealing, and crying sounds often mistaken for trapped birds.
- Frequent Daytime Activity: While raccoons are strictly nocturnal, a mother with young will often be seen coming and going in broad daylight to feed herself so she can nurse.
- Nesting and Waste Areas: Raccoons will tear up fiberglass insulation to build a soft, warm nest. They will also establish a “latrine” area for bathroom waste, which causes a strong, foul odor that may eventually seep into your ceiling or walls.
- Heavier Scratching: Adult raccoons are quite heavy (up to 20 lbs). If you hear slow, heavy stomping or scratching in addition to the babies’ cries, a family is likely up there.
Structural Destruction: Damage in the Attic
Raccoons are not just noisy guests; they are destructive tenants. Their high intelligence and powerful hands allow them to tear apart home structures in hours. Common damage includes:
- Insulation Trampling: They crush and shred fiberglass or cellulose insulation to build nests, drastically reducing your home’s energy efficiency.
- Chewed Wiring & Pex: Raccoons often chew through electrical wire coatings (a major fire hazard) and even plastic water lines, leading to hidden leaks.
- Truss & Vent Damage: They can rip through soffit vents, roof shingles, and even structural trusses to create or enlarge entry points.
The Biological Hazard: Raccoon Roundworm (Baylisascaris procyonis)
Beyond structural damage, raccoons pose a severe health risk through the spread of Baylisascaris procyonis, a parasitic roundworm that lives in the intestines of raccoons. Their microscopic eggs are shed in the raccoon’s feces.
- Raccoon Latrines: Raccoons designate specific areas, often in attics or near home foundations, as ‘latrines’ for defecation. These areas become concentrated hot spots for millions of microscopic roundworm eggs.
- Extreme Resilience: Roundworm eggs are exceptionally hardy, surviving extreme temperatures and standard disinfectants. They can remain infectious in the soil or insulation for years.
- Human Risk: If inhaled or ingested—often accidentally by children or during unequipped DIY cleanup—these parasites can cause devastating neurological damage, blindness, or even death.
Because mother raccoons can become highly aggressive if they feel their kits are threatened, and because of the severe biological risk, it is strongly advised to contact a licensed local wildlife removal professional. They can safely and humanely relocate the entire family and perform proper scientific remediation without leaving babies behind or spreading infectious pathogens.
