Hi Scally. Longstrider is correct re the professional pest control of these enchanting creatures. They have the strange tag of 'protected pest' although this has been regraded downwards as of last year. All around the village in September there are always complaints of Glis trying to find their hibernating spots and as they are nocternal and terribly noisy and destructive they have to be dealt with. We still have a release programme and a colony locally. Sometimes,unfortunatly, the pest control man has to visit.
I have never eaten one but I really should. You probably know the Roman way of keeping one in a clay pot and feeding it up untill it was very fat then cooking the pot with glis inside. Good fresh travelling food.
The worst incidences are when they drown in the water tank in the roof and the whole family gets a tummy upset.
We had one (may have been more) last year in the eaves of the shed and when gently poked sounded like a giggle stick! I'm sure that the same one was caught in our bathroom having scaled the brick wall to climb in up onto the bathroom shelf and was caught licking my wifes weatgerm oil. I caught him in a towel and put him in the garden. They tend to shy away from our loft as there is ferret poo up there for that reason!
I really should not say this but they make good pets unlike a grey squirrel!
We are south of tring. I do not think that they get beyond Wycombe. Certainy if you mention the glis word there you are asked to explain yourself. (no insult to Wycombe!)
