I actually scared it off from our flat. I use a boom to pock the ceiling whenever I heard the sound and the possum eventually went away. We called pest control but they didn't find anything but saw the biting (or claw) marks on some parts of the wooden structure. We flatted in an old villa. May be you can try to scare it first and call pest control again if it continues. 作者: xytdt55 时间: 2015-12-16 11:41:02
