Are Pigeons in Toronto a Health Risk?
By PestRecord Editorial Team
Pigeons are a fixture of Toronto streets. They cluster on building ledges, park benches, and transit platforms. But are they actually a health risk to GTA residents? The answer is nuanced and depends on how much contact you have with pigeons and their droppings.
What Pigeons Actually Carry
Pigeons can carry bacteria and parasites. The diseases most commonly cited are histoplasmosis, psittacosis, and pigeon mites. Here is the honest picture of each.
Histoplasmosis
Histoplasmosis is a real fungal infection caused by breathing in spores from dried pigeon or bat droppings. The key word is dried. Fresh droppings are not the issue. Histoplasmosis occurs when droppings have accumulated in an enclosed space over time, dried out, and been disturbed.
In the GTA, histoplasmosis is rare. Attics and crawlspaces where pigeons roost for years can develop the conditions. A pigeon sitting on your balcony railing poses no histoplasmosis risk.
Psittacosis
Psittacosis is a bacterial infection that can pass from birds to humans. It is associated with infected parrots and parakeets more than pigeons. Cases in the GTA are extremely rare. Symptoms resemble flu and respond well to antibiotics.
Pigeon Mites
Pigeon mites are small parasites that live on pigeons. When pigeons leave a roost, mites search for a new host and may bite humans. The bites cause itchy red welts. This is a nuisance rather than a serious health concern, and it resolves with professional pest treatment.
Who Is Actually at Risk
Healthy GTA residents have very low risk from pigeons. Higher-risk situations include: people with compromised immune systems, people with chronic lung disease, and construction workers disturbing large, old pigeon roosts without protective equipment.
The Real Issues Are Different
For most GTA property owners, the bigger concerns from pigeons are:
- Slip and fall liability: Wet pigeon droppings on walkways are a genuine slip hazard.
- Property corrosion: Pigeon droppings are acidic and damage metal, stone, and paint over time.
- Parasites: Mites and loft beetles infesting buildings near roosts.
