Hi wce,
there is no grass in my backyard, lots of sheds but I don't believe they are living in those because the dog would sniff them out. There is a big liquid amber tree but that has no leaves on it at the moment and I have corrugated iron wrapped around it but when the dog chases then the somehow still manage to get up the tree. There is a couple of bottle brush trees (one is pretty mangled now after I attacked it one night about 11pm in the rain in me slippers and dressing gown because I thought they were getting into the liquid amber through this tree. There is a big fish pond with all the usual vegetation around it. Apart from that I'm not sure what it is that attracts them here, there is no food source that I can think of.
Hi AVB, yes it is not good but I think it is better than the Middle East and it only me against the possums.
Hi MF, it is all courts around here so no through traffic at any speed so I don't think that is going to help but at least last night was peaceful
