I am sure you have googled. Ths one seems rational. As someone who loses lots of fruit to other garden animals - it seem harder you try the more clever they become. I spent years putting netting over stone fruit trees which is a pain. The birds figure out how to cling and get an even better grip and the opossums and raccoons manipulate their way in. The horrid squirrels pick the oranges and pull the seeds out. What a waste. Rats on the under ripe avocados etc.... I would not go crazy. Let them have something if they really want it. Again I would talk to locals - neighbors and co-op to see what they experience in your area. Iguana mole or tamal?
