About 80% of homes in Somerville were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter. Summers in Somerville are milder, with July highs around 82 degrees, but guano in closed attics still dries and turns to fine dust over time.
The work often covers:
- Disinfection of wood framing, joists and hard surfaces with EPA-registered products
- Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures
- Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
- HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
- Cleaning of stained ceilings, walls and floors below an affected attic

Common Questions About Guano Removal in Somerville, MA
Does guano damage insulation?
Yes. Insulation soaks up droppings, urine and odor and rarely comes back clean, so soiled insulation is usually removed and replaced. A team can tell you how far the damage goes after seeing the attic.
What rules apply to guano cleanup in Massachusetts?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
Can pigeon droppings damage a roof or building?
Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.
Do I need to replace attic insulation after guano?
Usually, if droppings or urine have soaked into it. Soiled insulation holds contamination and odor and cannot be reliably cleaned. After removal, new insulation is installed as a separate job.
Do barns and old buildings need special handling?
Buildings with years of buildup can hold thick, dry, dusty guano that is easy to disturb. Crews ventilate, wet down and use respirators and containment to keep spores out of the air.
Is guano dangerous?
It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.
