Wild Brown Long-Eared Bat Welfare

Brown long-eared bats are specialist woodland hunters, vulnerable to roost loss from building work and woodland management.

Key Facts

Brown long-eared bats use their enormous ears to detect prey by passive listening
They hunt invertebrates by gleaning from vegetation and hovering around woodland edge
Brown long-eared bats use traditional roost sites in old buildings and trees for generations
Timber treatment chemicals during roost renovation cause bat mortality and roosting failure
Brown long-eared bats are protected under UK law from killing, capture, and roost destruction

Welfare Considerations

Brown long-eared bat welfare at roost sites is vulnerable to chemical treatments and building work. Mortality from timber treatment chemicals causes painful death for exposed bats. Building renovation without bat surveys risks destroying maternity roosts and killing pups. Pre-work surveys and bat-friendly alternatives protect individual bat welfare.

What You Can Do

Hire a licensed bat surveyor before any loft or roof work in older buildings
Choose bat-safe alternatives to conventional timber treatment chemicals
Support bat conservation organisations providing expertise on bat-friendly renovation
