I had a colony in my roof space when I lived in Edinburgh...the conversation with the Bat Protection League went something like;
(me) So, can I move them?
(TBPL) No.
(me)Can I cause them to move on in some way?
(TBPL) No
(me) Can I at least stop them from wearing boots and tapdancing in the attic
....muffled giggles......and a considered pause,br> (TBPL) You might try training them to wear carpet slippers...lots more muffled giggles
