What Wildlife Does to Your Attic — And Why It Can't Just Be Vacuumed Out
When squirrels, bats, raccoons, rats, or birds live in an attic, they don't leave it the way they found it. Insulation becomes saturated with urine, packed with feces, and shredded into nesting material that no longer performs its function. Bat guano accumulates in piles that harbor Histoplasma capsulatum — a fungal spore that causes histoplasmosis, a serious respiratory illness, when disturbed during improper cleanup. Raccoon feces can contain Baylisascaris procyonis, a roundworm with larvae that are dangerous to humans. These are not theoretical risks — they are documented health concerns that require professional decontamination, not a shopvac and a broom.
Beyond the health concerns, compromised insulation means your HVAC system is working harder than it should every single day. Insulation that's been saturated with animal waste loses its R-value almost entirely — it can look intact while providing almost no thermal protection. Urine-soaked insulation also creates a scent trail that attracts the same or different animals back to your attic after removal. The smell doesn't go away on its own. It compounds. Attic restoration removes the source of the problem rather than masking it.
Our attic restoration process is comprehensive: we remove all contaminated insulation, vacuum and wipe down all accessible surfaces, apply an EPA-registered biocide to decontaminate for pathogens and eliminate odor-causing bacteria, and install fresh blown-in insulation to your attic's recommended R-value. The result is an attic that is clean, safe, thermally efficient, and free of the scent traces that attract future wildlife. We photograph before and after so you can see exactly what was done.
Known Health Risks From Wildlife Waste in Attics
- Bat guano → Histoplasma spores → histoplasmosis (respiratory)
- Raccoon feces → Baylisascaris roundworm → can affect humans and pets
- Rat urine → Leptospira bacteria → leptospirosis
- General animal waste → mold growth → ongoing air quality degradation
- Disturbing dried waste without proper PPE releases airborne pathogens
These risks make DIY attic cleanup genuinely dangerous. Professional decontamination with appropriate PPE and EPA-registered biocides is the safe approach.
Our Attic Restoration Process
Inspection & Documentation
We perform a complete attic inspection, document the extent of contamination with photos, assess insulation R-value loss, identify all areas of structural damage, and provide a detailed written restoration proposal. You see the full picture before any work begins.
Contaminated Insulation Removal
All contaminated insulation is removed via industrial vacuum equipment directly into sealed disposal bags. We do not disturb waste without appropriate PPE. Every area of the attic floor is cleared down to the decking so decontamination can reach all surfaces.
Decontamination & Odor Elimination
All accessible attic surfaces — decking, joists, rafters, blocking, and any remaining structural elements — are sprayed with an EPA-registered biocide. This eliminates pathogenic organisms, mold spores, and the odor-causing bacteria in animal waste. The biocide is allowed to dwell and dry fully before new insulation is installed.
New Insulation Installation
Fresh blown-in insulation is installed to Georgia's recommended R-38 to R-60 attic insulation level. We use insulation appropriate for your attic configuration and provide documentation of the R-value achieved. Your attic is left clean, sealed, and thermally efficient.
What Our Customers Say
"We bought our house not knowing squirrels had been living in the attic for years. The smell was awful and the insulation was destroyed. TOG removed everything, decontaminated the whole space, and blew in new insulation. The difference in both smell and our energy bills was immediate."
— Sandra M., Carrollton, GA
"I was worried about the health risk from the bat guano that had built up. David explained the histoplasmosis risk clearly, suited up with proper equipment, and handled the whole decontamination professionally. Felt completely safe the whole time."
— Robert T., Alpharetta, GA
"The before and after photos they sent me were shocking. I had no idea how bad it had gotten up there. Completely clean now and my energy bills have dropped. Very professional operation."
— Lisa W., Newnan, GA
