Get a box trap, put it somewhere the nosy neighbor can't see it. Bait with peanut butter. Once you catch them, take them inside and kill them. Repeat x 100. I don't like killing stuff just for sport, but there may come a time when you HAVE to kill something. It is a useful skill.
The previous owner of our farm house must have had 4-5 squirrel feeding stations in the yard. We were overwhelmed. They were in the attic. They were in the walls, they would tear up the garden, etc.
I quit counting when I got close to 100 shot/dead. The chipmunks were just as bad.
Now I occasionally see a squirrel in the back woods, but they shy away from the house and garden.
Do away with them, as many as you can.
On a side note,,,
Are you making plans to move, so you can defend yourself from vermin?
Good luck!
