I’m in the pellet rifle group. With scope and silencer. They are not illegal inside the city limits in Florida. You don’t have to kill them all. Kill one and bleed it out around your plant area. The rest of them won’t come near the area for a couple of months till the smell of squirrel blood dissipates. We can’t smell it, but they sure can and won’t go near it. I’ve found about 2 months is good unless there is a lot of rain to wash it away.
