Bats are amongst our most fascinating and enigmatic wild animals. We still know very little about most of our species. What we do know however is that populations of all our commoner species have decreased greatly over the last 60 years. One species recently became extinct in Britain and others are now seriously endangered. The Herts and Middx Bat Group are working to further bat conservation in Hertfordshire and Middlesex. We also provide advice and information for householders and landowners and hope that you find our website a useful resource. Please don't hesitate to contact us if you have a bat related query.


The bat pictured above is a Nathusius' pipistrelle

A Bat's life: November
Increasingly bats are hibernating as reliable insect food supplies disappear. By going into states of torpor they save energy and can survive the winter. It's essential that torpid bats are not disturbed as they may be unable to replace the energy they use waking and warming.


If you have found a bat which you believe may require help (i.e. one that’s grounded, in the open during daylight hours, caught by a cat, or within the living area of your property) then please call us on 07517 123 200 or if that is unavailable please call the BCT helpline on 0345 1300 228 at the very first opportunity, rather than using email. We can respond much quicker and we'll guide you through some immediate steps which will reduce your concerns and greatly increase the bat's chance of survival and recovery. Grounded bats in particular need protection from cats and inclement weather as soon as possible. If you find a bat flying around inside your property please refer to the ‘Need help with a bat?’ section of the website.
