In autumn the beetle tries to hibernate in warmer spots like your glass house or flat. Inside the living rooms, there is danger neither to the furniture nor to your health. Sometimes it likes to crawl up about 1m on white garden walls, where I found most of my beetles. Whenever you touch a beetle, it will fall down and mimick death material for a while. Whereas in the open this type of damage can be tolerated or ignored, it is much more dangerous under glass, because the weevil is said to have several generations here.
Weevils are said to be polyphytophageous, i.e. they eat what they see or smell.
An infection inside a glass house may destroy complete plant cultures as cyclamen or begonia, where the larvae like to live in the tuberous roots. Commercial indoor plant growers know about the potential danger from the weevil and are trained to combat the beetle and the larvae. In open ground plants, damage may become visible, but is mostly too small to be of any concern. Also the scion of grafted plants can be found girdled. Wine plantations may be completely lost unless immediate action is taken.
