Cool idea,if it gets the job done awesome.

Cool! I bet the noise and wind scares them off.

Did you spot the interloper in the corner? I went back to look after posting, and there were 2 in the lily below.

yeah, I can see his beady little eyes.

I'd like to sink/stand pvc pipes near at each corner to support a shelf or hanging rods above to expand this squirrel-free area. As long as I don't hit a pipe or cable in the ground, do you think this is a worthwhile plan?

(I run the HVAC 24/7 because of cat litter boxes in house as well as high humidity.)
