An attic guano cleanup removes droppings from joists, beams and insulation, and treats the structure afterward. Insulation soaked with guano is usually discarded because it holds odor and contamination.

Many homes in Los Angeles, about 70%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell. Valley Glen is on the drier side, with about 14 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal.

No. Cleanup removes the mess but does not block entry points. A wildlife professional can seal gaps and use deterrents. Removing droppings and odor does help, since scent can draw animals back.
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.
The animals come out first. Wildlife professionals handle exclusion, and rules about bats can vary by species, season and place. Cleanup follows once the space is no longer in use by animals.
