I feel your pain. Some animals had a party on my peach tree last night. Despite all the protective measures (tube trap, motion-activated sprinkler), about 40 nearly ripe peaches disappeared - only two were left. I already had a good harvest from my Contender peach, but I left some peaches on the tree to ripen further. I guess that was my mistake.
The tube trap was triggered but didn’t catch anything, and the peaches are gone. No broken limbs - just a couple of small twigs on the ground. No peaches on the ground either; it was a very clean job.
Since it happened at night and I haven’t seen squirrels around lately, I’d rule them out. It’s probably either raccoons or a possum.
