Hi Norm and all small animal lovers
Is there some sort of very attractive food source in your trees Norm ? or are they using the trees to roost in ?
Have you tried putting smooth metal sheeting around the trunk of the tree a bit up from the ground and extending up a few meters so they cant climb the tree ?
Maybe if they don't like water get a tree climber to run some cheap retic pipe up the tree with sprayers that you can turn on and off via a tap timer ? at least you won't have to stand outside in cold weather at night.
Cheers
