Bat guano removal is the careful collection of bat droppings, usually from attics and wall voids, using wet methods and containment. It protects people from dust that can carry fungal spores.
Guano is a respiratory risk, so your Waianae property gets containment, wet methods and protective gear, then disinfecting and inspection before the space is handed back to you. For Honolulu County owners, call Waianae Biohazard Cleanup Help.
Waianae is on the drier side, with about 22 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal. Most housing in Honolulu County is occupied, with a vacancy rate of about 10%, but attics, chimneys and outbuildings can still go unchecked for years.
A typical bird & bat guano cleanup job includes:
A cleanup technician maps the droppings, stains and damaged insulation in attics, lofts or on rooftops.
Heavy or caked droppings are softened with a light mist so they can be lifted without raising dust.
Guano, soiled insulation and nesting debris are removed by hand or with HEPA-filtered tools and sealed in heavy bags.
HEPA filtration clears the air, surfaces are disinfected, and the owner is walked through the result.

Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.

Yes, mainly from breathing in dust from dry droppings. Risk is higher with old, heavy buildup in enclosed spaces. People with asthma, lung conditions or weak immune systems need extra care and should stay out of the area.
Large amounts of bird droppings are treated as a contamination hazard because they can hold germs and fungal spores. A small spot outdoors is a simple wash. Thick buildup in a closed space needs protective gear and wet methods.
Tell the team what you found and it explains the next step.
