Many homes in Portland, about 63%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell. Cully gets about 44 inches of rain a year, and damp air keeps guano and soaked insulation wet, which strengthens odors and encourages mold on wood.
The work often covers:
Family members, tenants, staff and pets stay out while the crew plans the work and gets into protective equipment.
Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.
Droppings are wetted, scraped and collected, and insulation that cannot be cleaned is cut out and bagged.
