Wild Bat White-Nose Syndrome and Welfare

The devastating welfare and conservation impact of white-nose syndrome on North American bat populations.

Key Facts

White-nose syndrome has killed over 6 million North American bats since first detected in 2006
The fungal disease Pseudogymnoascus destructans disturbs bat hibernation causing fatal energy depletion
Affected bats awaken repeatedly during hibernation, burning fat reserves they need to survive winter
Some species have declined by 90% or more in affected areas, raising extinction concerns
A probiotic treatment using a naturally occurring bacterium that inhibits the fungus shows promise
Bats are critical ecosystem service providers as insect predators, reducing crop pest pressure significantly

Welfare Considerations

White-nose syndrome causes welfare harm through a specific mechanism that is particularly distressing: disrupted hibernation that causes bats to slowly starve as they burn energy reserves during repeated unwanted awakenings. The welfare experience of dying bats — repeated disorientation, cold stress, and progressive energy depletion — is a form of suffering that occurs at enormous scale across millions of individuals. Conservation responses including probiotic treatment and hibernaculum management improve both survival rates and the quality of the dying process for bats that cannot be saved.

What You Can Do

Support Bat Conservation International working on white-nose syndrome treatment and bat population recovery
Install bat boxes to support local bat populations affected by white-nose syndrome
Avoid disturbing bat hibernacula during winter months when disturbance causes fatal energy loss
Donate to research on probiotic treatments and other interventions for white-nose syndrome
