Bird guano removal is the safe clearance and decontamination of accumulated droppings from roofs, ledges, fire escapes, car parks and plant areas — work that needs COSHH controls and respiratory protection, because dried droppings can release airborne pathogens when disturbed, not just a wash-down with a hose. Optus Glean UK removes bird guano safely across the UK, fully insured.
Why bird guano is a health hazard, not just a mess
HSE's construction guidance on harmful micro-organisms names psittacosis — caused by the bacterium Chlamydia psittaci and spread by inhaling aerosolised dried droppings, causing "a flu-like illness and pneumonia" that usually appears 5-19 days after exposure — and salmonella (causing significant diarrhoea) as risks linked to bird droppings. Large or long-standing accumulations of bird droppings are also linked internationally to fungal infections such as histoplasmosis when disturbed, though this is reported far less often in UK guidance than psittacosis. Either way, guano should be treated as a biohazard, not routine mess.
How we control the risk
HSE's guidance is explicit that work should avoid generating dust: wetting down the work area before disturbing droppings, and specifically warning against high-pressure washers because they "create contaminated airborne droplets". Our operatives use RPE to the standard HSE specifies for this work — "an assigned protection factor of 20 (eg FFP3 disposable mask or half mask with P3 filter)" — plus disposable coveralls and gloves, and work to a task-specific COSHH assessment.
Safe removal and disposal
Guano and contaminated debris are bagged and handled as hazardous waste, and affected surfaces are cleaned and disinfected after physical removal. HSE's hygiene-control guidance for this work includes regular hand-washing and provision of nailbrushes, which we build into our site procedures. Where volume or contamination warrants it, waste is routed through a licensed carrier.
Where we do this
Roofs, gutters, ledges, fire escapes, external plant and air-handling units, car parks, walkways, and industrial or warehouse eaves — for facilities managers, landlords, and industrial or logistics sites. Work can be paired with bird-deterrent recommendations for recurring roosting sites, and run as a scheduled programme across a multi-site estate under one arrangement.
