Q.I am sure squirrels are eating my immature apples.
I have tried wrapping trunk in drain-pipe, putting human hair around and hanging a biological soap next to trunk, all ideas from the internet but each year nothing works. Any sure fire advice please?

Squirrel traps, poisons, and extermination are all surefire ways to rid squirrels from the yard, AS LONG AS THEY ARE NOT A PROTECTED SPECIES IN YOUR AREA. Unfortunately, they are quite intelligent, and will get around most efforts to keep them away.
