Thanks for the replies.
The problem I face here is the birds are constantly “testing” the apples. Even at the 1" size they will peck at them to see if they are ripe/good. And like many critters, they don’t just test one; they feel the need to test as many as they can reach. The damage varies year to year, but in a bad year I can loose 80% of the apples to birds.
I have tried netting (forget if it was the bird-x brand) and that was marginally effective. Birds still went for the apples, many got tangled in the netting and died, and the netting itself did quite a bit of damage due to how long it needed to stay on for and our winds. And I have too many big trees now to throw nets over them.
What I was considering was the Bird-X repellent spray (I think that is Bird Stop). Extracted from grapes and smells like them too. I was hoping some of the folks here had used it and could report. Online it has very mixed reviews, some love it some hate it. Since it only comes in a gallon for almost $100, I would like to hear from some fruit growers that it works before trying some.
Anyone have experience with Bird Stop?
