Bats benefit both natural ecosystems and people. Viruses that live in bats can harm people, but transmission of these pathogens from bats to humans can occur only when humans come too close to bats. Recently, misguided attempts to preserve human health have led to persecution of bats. In fact, however, what will keep people healthy is to protect bats and their habitat. This 4-page fact sheet written by Holly K. Ober and Samantha M. Wisely and published by the UF/IFAS Department of Wildlife Ecology and Conservation explains how protecting bat roosts can reduce the likelihood of future zoonotic disease pandemics while also increasing the natural pest reduction services bats provide as they consume insects that cause damage to agronomic crops as well as the mosquitoes that transmit diseases like Zika, dengue, malaria, and chikungunya. Finally, protecting bat roosts keeps bats safely distanced from people, whereas destroying their homes risks the health of both people and bats because it forces bats into closer proximity to people.
