I have hundreds of them here and consider them to be "tree rats". Every chance I get I shoot them and I praise the dogs when they kill one. They steal the fruit off my trees, strawberries from the garden, etc.
The pool photos have me thinking of putting a small island covered in nuts in the center of the pool.
I have a pool an for the last 14 years there never has been a drwoned squirrel.
The list of drowning victims;
large opposium, 10-20 alligator lizards, 10-20 blue belly lizards, couple of birds, 2 auto pool vacuums, no squirrels
