Pigeon Droppings Clean-up & Decontamination in French-speaking Switzerland
Safe, professional removal and decontamination of pigeon droppings. Essential before any deterrent installation, and critical for protecting health in affected buildings.

Why Professional Droppings Removal Is Essential
Pigeon droppings accumulate rapidly wherever birds roost consistently. A small colony of 20 pigeons produces roughly 12 kg of droppings per month. Over time, this builds up into deep layers on ledges, rooftops, balconies and in loft spaces, creating a hazardous material that must be handled with appropriate precautions.
Beyond the immediate health risks (see below), accumulated droppings cause ongoing corrosion damage to building materials. The uric acid in pigeon faeces attacks stone, concrete, painted metal and render, accelerating structural deterioration and necessitating costly repairs if left untreated.
Professional droppings removal is also an essential first step before installing any bird deterrent system. Pigeons are strongly attracted to areas that smell of other birds — the chemical signals in existing droppings actively attract new birds to roost in the same location. If spikes or nets are installed over existing fouling without decontamination, pigeons may continue to try to access the area, or simply move to an adjacent surface. Full decontamination removes these attractant signals.
Health Risks from Pigeon Droppings
Cryptococcosis
A fungal infection caused by Cryptococcus neoformans, found in pigeon droppings worldwide. Inhaled spores can cause serious respiratory illness and meningitis, particularly in immunocompromised individuals.
Psittacosis (Ornithosis)
Caused by the bacterium Chlamydophila psittaci. Symptoms resemble severe pneumonia. Transmitted by inhalation of dried faeces or secretions. Requires antibiotic treatment.
Histoplasmosis
A fungal respiratory disease caused by Histoplasma capsulatum, which grows in soil or accumulated bird droppings. Can cause severe lung disease in susceptible individuals.
Salmonellosis
Salmonella bacteria present in pigeon faeces can contaminate food preparation surfaces or water supplies in affected buildings.
Allergies and asthma
Dried droppings and feather debris release fine particles and proteins that act as allergens, triggering or worsening asthma and allergic reactions with prolonged exposure.
Ectoparasites
Pigeon nests and droppings often harbour mites, lice and fleas that can bite humans and cause skin irritation, and in some cases transmit disease.
Our Droppings Clean-up Process
Assessment and protection of surroundings
We assess the quantity and extent of the fouling, identify any areas below that could be affected by dislodged material, and protect them as required. All work areas are isolated from occupied spaces where practicable.
Dry removal in full protective equipment
Our technicians work in full protective suits (category 5/6), gloves, boots and FFP3 respiratory protection. Accumulated droppings are carefully scraped and collected using specialist tools, placed into sealed biohazard bags and disposed of as contaminated waste in accordance with Swiss regulations.
Biocidal disinfection
After mechanical removal, the cleaned surfaces are treated with a professional-grade biocidal disinfectant that eliminates residual bacteria, fungi and parasites. This step also neutralises the pheromone attractants that would otherwise draw new pigeons to the site.
