I guess, I've been lucky. I haven't lived in a neighborhood with known squirrels since the 70's. The last three, the trees have been too small. Here we have freakin rabbits. They keep digging ditches around our fence and they get into my wife's garden.
A few houses back we had some pest in our roofing. We thought they were squirrels and one day a nasty burnt smell came from the A/C. I called the A/C guy out...it turned out to be a baby racoon that got in the blower.
