What protective measures should people working in bat roosts take?

Individuals working in bat roosts should wear respirators and protective clothing as a vital protective measure. Bats can carry diseases such as histoplasmosis, rabies, and other zoonotic pathogens, and direct contact or inhalation of bat droppings (guano) can pose significant health risks. Respirators are important for filtering out airborne contaminants to prevent respiratory issues, while protective clothing helps minimize skin exposure to potentially harmful elements.

Wearing casual clothing would not provide sufficient protection against biological hazards present in these environments. Sharing food with bats is not only inappropriate but could also lead to increased risk of transmitting diseases. Ultrasonic repellents are not typically effective at controlling or preventing bat infestations, as bats are not significantly deterred by sound frequencies in the ultrasonic range. Thus, opting for respirators and protective clothing is essential for ensuring safety when working in bat roosts.
