Getting the bats or wildlife out is step one. Dealing with what they left behind is step two, and it is not optional when the contamination is significant. A bat colony that has been using an attic as a maternity roost for five or ten years leaves behind accumulated guano, urine staining, and potentially hundreds of pounds of material that has soaked into and degraded the insulation below. That material carries health risks and insulation that no longer performs to spec.
This is the part of wildlife removal that less experienced operators skip or underquote. We do not skip it. We tell you what is in there, what needs to come out, what the health risk is, and what it costs. Then you decide.
Histoplasma capsulatum is a fungus that grows in bat and bird guano. When dried guano is disturbed, spores become airborne. Inhaling them causes histoplasmosis, a respiratory illness that ranges from flu-like symptoms in mild cases to severe lung disease and systemic infection in serious ones. Older adults and anyone with compromised immune function are particularly at risk.
This is not a hypothetical concern in Wood County. We are in the Ohio River valley, and Histoplasma is endemic to this part of the country. Attics in older Parkersburg homes that have had bat colonies for decades are legitimately contaminated environments that need proper remediation, not just a sweep and a new bag of blown insulation on top.
Raccoon waste carries its own risk: Baylisascaris procyonis, the raccoon roundworm. The eggs are microscopic and persist in soil and attic insulation for years. Proper cleanup matters here too.
Full attic restoration in the Parkersburg area runs $1,500 to $4,000 depending on attic size, depth of contamination, and insulation type needed. Small attics with limited contamination are at the lower end. Large Victorian attics with years of accumulated guano and full insulation removal required are at the higher end.
We assess each job individually. We do not charge a flat rate and then upcharge when we see the conditions. You get a written quote before anything starts.
Yes. Bat guano can carry Histoplasma capsulatum, a fungal spore that causes histoplasmosis, a respiratory illness that ranges from mild to severe. When guano dries and is disturbed, the spores become airborne. Attic guano accumulated over years should not be handled without proper respiratory protection and should be removed by someone trained in the process.
Full attic restoration in the Parkersburg area typically runs $1,500 to $4,000 depending on attic size, depth of guano accumulation, insulation type, and total square footage requiring replacement. We assess every job individually and give you a written quote before work begins.
No. Adding new insulation over contaminated insulation traps the hazard in place. You still have the Histoplasma risk, the odor source, and the degraded R-value underneath. Proper restoration requires removing the contaminated material, treating the substrate, and installing fresh insulation on a clean surface.
Signs include visible guano on the insulation surface, brown or dark staining, persistent odor in the living space below, or a colony that has been present for more than one season. We assess every bat job and give you an honest opinion on whether restoration is necessary and how urgent it is.
