Remove dirt without sending it into the air
Prepare suitable tools and a contained waste route before starting. Avoid vigorous dry sweeping, compressed air and methods that raise clouds of droppings dust. Bird-associated dust can affect human health; the appropriate controls depend on the task and contamination. Seek occupational health or specialist cleaning advice for substantial accumulations or higher-risk work.
Keep birds away from active cleaning, chemical exposure and disturbed debris. Where an appropriate low-dust method uses moisture, avoid soaking the building or spreading contaminated water into hidden joints. Remove waste in a controlled way, keep work clothing and equipment separate from food preparation, and wash hands thoroughly afterwards. Protective equipment does not replace reducing exposure at its source.
Clean first; disinfect only with a clear method
Visible organic material can interfere with disinfectants, so remove dirt and clean the surface before any required disinfection. Use a product suitable for the intended application and follow its label for dilution, contact time, compatibility, rinsing and drying. Do not invent a stronger mixture in the hope of making a job safer.
Never mix chemicals, especially bleach with acidic or ammonia-containing products. Store products securely outside bird accommodation and keep them in their original labelled containers. Ask a veterinarian for disease-specific hygiene advice when illness has occurred; a general routine cannot establish the correct response to every infection. Return birds only when conditions are safe and surfaces are appropriately dry.
Follow the water after bad weather
Start from a safe position at ground level. Look for displaced cladding, damaged barriers, blocked drainage and obvious changes around doors or accessible roof edges. Inside, check the underside of vulnerable joints, floor margins and the backs of removable components. A dry-looking central floor does not rule out water entering along a wall.
Distinguish rain entry from condensation and spilled drinking water by noting when the dampness appears and how it is distributed. Fix the source rather than repeatedly covering the mark. Do not climb a wet roof or stand on improvised platforms. Structural movement, damaged electrical equipment and unstable roofing require qualified assessment and may mean birds need temporary safe accommodation.
