Hi bgli,
You need to thin the herd of pests ...
You need to keep your backyard clean with no food for them. Do you have a bird feeder for the winter ? ... Step one : Trash it .
If you have several fruit trees, keep them clean, with no fruit left over, no fruits out of reach, and no fruits that you won't harvest. I often hear people saying : "my cherry tree is too big but that feeds the birds ..."
Pruning helps a lot in keeping the trees clean from overripe fruits.
You can try some plastic bags or cds hung in the trees or "funny" windmills, some they make random noise and that helps in scaring the pests .
Then you'll have stubborn pests ... For those ones, there is only one solution : getting rid of them or they'll teach the others that your fruits are safe to eat ...
As for the netting, a cage around the tree is better . If you apply the net directly on the tree, the efficiency won't be worth it, especially since better ripe fruits ... are at the tips of the branches .
There is a topic here on the forum about at least one caged fig tree. You could use that kind of solution .
Another solution is to use small "organza bags" and bag each fruit. Last year, I split a shirt into pieces and would put them around the fruits 1 or 2 days before full ripeness .
It was "most of the times" efficient but was time consuming ...
But for a backyard production so that is done for fun, it works .
I just got sick because my only 2 "Pastiliere" got ripe at the same time and I only detected one going into ripeness ... I got the one, and the birds got the second ( and so I knew it had started to ripen :( )...
