Guano, particularly from pigeons, sparrows, and starlings common in the Inland Empire, can harbor fungal spores like Histoplasma capsulatum, which cause respiratory illness when disturbed. The uric acid in bird droppings also corrodes roofing materials, metal surfaces, and painted finishes over time, leading to costly repairs if left untreated. In Ontario’s warm, dry climate, dried guano becomes powdery and easily airborne, increasing the risk of inhalation during cleanup. This is why a professional, containment-based approach is essential—not a simple power-wash. The cleanup process begins with a thorough assessment of the affected area, which may include attic spaces, ledges, balconies, or exterior walls. Technicians wear full personal protective equipment (PPE) including respirators, disposable suits, and gloves to prevent exposure. The area is first wetted with a disinfectant solution to suppress dust and neutralize pathogens before any scraping or removal begins. Contaminated materials—such as insulation, nesting debris, and accumulated droppings—are carefully bagged and sealed for proper disposal in accordance with local waste regulations. After removal, all surfaces are treated with a hospital-grade antimicrobial and deodorizing agent to eliminate remaining bacteria and odors. The final step involves sealing entry points and installing deterrents like bird spikes or netting to prevent re-infestation, which is particularly important for Ontario commercial properties where ongoing maintenance is critical. ## Areas We Cover in Ontario We provide bird dropping and guano cleanup services throughout Ontario, including neighborhoods like Central South, Creekside Community, Cucamonga, Glen Avon, Mira Loma, and Ontario Ranch.
