Glis Glis/Edible Dormouse/Grey Dormouse

The Edible dormouse is a nocturnal animal, spending a lot of time in trees at night, feeding and possibly defending territories. There has never been a full scale survey carried out on this animal.I have often had clients telling me that they leave and enter their lofts at a particular time and place in the loft. Whilst in the property they will follow the routes of water pipes and will enjoy sleeping on towels etc in airing cupboards. They also find themselves under sink units, in food waste bins (as will rats!).

Outside of the domestic environment they will feed on fruits, leaves, bulbs, insects, bird eggs and nestlings, feeding in trees. Glis Glis need to gain weight because as Autumn approaches they will hibernate from October (ish) till May (ish). Each year will be different due to the environmental differences. They will hibernate below floor boards, under tree roots and below ground, quite often in groups. They require a cold environment; to lower their body temperature and heart rate, to allow slow digestion of their stored body fats.

 

The Edible dormouse will breed in their 2nd/3rd year of life.It is reported that only one litter a year will be raised with up to 7 in a litter. This makes sense as the young will need to put on body weight to survive winter and with not arising from hibernation till May, and a gestation period of about it’s believed of 21-25 days.The mother will suckle her young, with the pair getting into breeding condition, a gestation period and weaning and adding body weight does not leave any time for a second litter.

 

They do leave multiple droppings in lofts, airing cupboards etc.  There is usually a musky smell in lofts during breeding seasons as a result of scent marking. They are also very noisy running and jumping about in lofts, sometimes drowning in uncovered cold water tanks, chewing and damaging electric cables and plastic water pipes, raising young in lofts, nesting in stored boxes and displacing loft insulation. They will also strip bark back from trees causing death of the tree, or an entry point for fungal infection.
