Bests & Worsts Reviews from Amazon

I had bird poop all over the balcony railing and light fixtures. Bought the owl and it worked for a few days. Bought other spinning reflectors, tape, etc. online and they only work for a few days. THEN I had a desperate but ridiculous idea to cover the railing with foil so it is easier to clean the poop. That was a stupid idea since the wind blew the foil away. But WAIT! One a piece of foil paper was still stuck under the owl and OMG it WORKED to deter the birds 100%. I now have ZERO bird poop. I was skeptical so I removed the foil and the birds were back within a day. The 10 cents worth of foil lasts for about two months (YMMV depending on winds). Try it, good luck.
