White-nose Syndrome (WNS)

  • Bat carers should be aware of the symptoms of WNS which has devastated bat populations in North America.
  • These symptoms are:
    •  Bats with a white fungus (Pseudogymnoascus destructans), particularly around the nose, but also on the
      wings, ears and/or tail,
    • Bats clustered near the entrance of hibernacula, or in areas not normally identified as winter roost sites,
    • Bats flying outside during the day in temperatures at or below freezing, and/or
    • Dead or dying bats in or near hibernation sites.
  • In the UK (and Europe) the fungus is present but without the mass mortality or other symptoms observed in
    North America – suggesting that our bats have a resistance to the fungus developed over thousands of years.
  • BCT has released specific guidance for bat carers detailing signs to look for and processes to follow (see
    Further information, support and references for further details).
