Bird guano spreads diseases that cause severe health hazards requiring hospitalization in serious cases. When you disturb contaminated areas without wearing personal protective equipment, you release clouds of infected particles. This airborne dust remains suspended for extended periods, exposing everyone nearby to health risks. Children playing near affected areas face particular danger due to their smaller body size.

Pigeon waste accumulation creates significant risk in enclosed spaces like roof voids and plant rooms. Workers entering these areas without appropriate personal protective equipment can inhale concentrated doses of harmful pathogens. The consequences can be severe, ranging from flu-like symptoms to chronic lung conditions.
