Found guano in a hard or unsafe place to reach in Ontario? People in San Bernardino County call Ontario Biohazard Cleanup Help and get a cleanup team that works discreetly, explains each step and sorts what you can keep from what must be discarded.
Most housing in Ontario is occupied, with a vacancy rate of about 4%, but attics, chimneys and outbuildings can still go unchecked for years. Ontario is on the drier side, with about 12 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal.

Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.

It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.
The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.
