That would probably work - but where to run the wire? In the rural garden, I have 36" of chicken wire low, and charged wires up to 6'. The lowest wire is located just above the chicken wire; that works for deer, raccoons, and discourages groundhogs (until they dig under). Few rodent problems there, in spite of nearby hickories... the owner's dogs & cats keep them at bay.This is probably not useful for most people but I had a solar electric fence charger leftover from a brief stint raising grass feed beef and .. if you take a charger meant for miles of wire and you put it on a single 115' strand around a garden at squirrel height, it makes an impression. ;-)
But at home, just chicken wire below, and welded wire fencing to 6'. I've watched the squirrels jump nearly to the top of the fence from the ground. There are black walnut trees across the street, and oaks & hickories just up the block... so like @Ridgerunner stated, I have A LOT of squirrels. They are everywhere, and causing structural damage, so I'm in favor of anything which would reduce the population. My live trap has been less than effective, so I'll give that BOSS a try.
Surprisingly, the squirrels are not a major problem in the garden. The only issues I've had were their pulling up bean sprouts once, and their pathological hatred of anything in pots.
