Just looking for any experiences and advice about these critters.
Several neighbours - ours is a terraced house and that includes people in the next terrace as well - have had, indeed still have, problems with Glis glis in their attics, airing cupboards, cavities, etc. We are located right by some extensive woodland from where they are thought to have wandered.
We have found no physical evidence within our house. But we have heard noises, location difficult to identify but generally "up", so are suspicious. Others have had various traps fitted - and have left apples as bait. And found droppings on their airing laundry.
