If you see pigeon droppings building up on ledges, plant decks, or walkways, it’s important not to just treat it as an aesthetic problem.
Leaving guano to sit on commercial property creates three distinct risks that require immediate action.
1️⃣ Structural and material corrosion
Pigeon droppings contain high concentrations of uric acid. Left untreated, it actively eats through protective paintwork, powder coatings, galvanized steel, and stonework. It degrades hydraulic seals on rooftop plant machinery and corrodes air conditioning casings, turning a simple cleaning requirement into an expensive structural repair.
2️⃣ Airborne health risks and biohazards
Guano harbours harmful pathogens including ornithosis, listeria, and e-coli. When droppings dry out, routine foot traffic or air intake systems disturb the material, sending microscopic dust into the air. Inhaling these airborne spores can even cause respiratory illnesses like psittacosis and cryptococcosis. In addition, dry guano on external walkways creates a severe slip hazard, while active nesting sites frequently attract secondary infestations of bird mites, fleas, and carpet beetles.
3️⃣ Environmental and legal compliance
Attempting to wash guano down standard surface drains or scraping it into general waste bins breaches waste management regulations. Bird waste is classified as hazardous biological waste, requiring disposal through a fully licensed Environment Agency waste carrier. Furthermore, because all UK wild birds, their active nests, and eggs are protected under the Wildlife and Countryside Act 1981, any clearance work must be carefully timed and managed to remain fully compliant with the law.
But the good news is, we can help. We are fully licensed to remove and clean bird guano. We are also Environment Agency Licensed waste carriers.
And when the cleaning is done, our bird control team will advise on the best bird deterrent to prevent the problem from happening again.
