Look I think brushtail possums are cute, but not cute living in the bedroom wall. Our possum originally got in months ago through a gap that was created between the old and new roof. After many nights of scratching in our bedroom wall, we blocked up that hole one evening when the poss went out.
Then our ducted air conditioning was put in, and our split system was removed. The split system had a drain onto our carport and the hole was blocked up with a piece of metal. Well cheeky possum pushed and scratched at the metal until he got back in. That hole is above where I sleep. So yet again we block the hole when the possum goes out one night. The first attempt at blocking was thwarted. The possum pulled a brick that was wedged into the hole out of the wall. So the next night Col put a piece of wood over the hole with a pile of bricks in front of it until he gets a chance to screw the piece of wood in. It's the kind of job where he needs daylight, so can't be done when he gets home from work in the evening.
Thought the problem was solved, but this morning I was awoken by the sound of scratching. That little bugger is try to scratch a hole into the eaves (see the area circled in red!).
So at 6am I was outside, throwing bits of gravel at the possum to make him go away. It took 4 or 5 times of him scampering away until he finally gave into my coercion. Col's going to patch that hole this afternoon. I am going to pressure him to put a box up in a tree for the possum. We really should have done that last time!
