What bait are you using in the live traps? Since they like your pears I would use that. I've also had good luck with walnuts placed in a fabric bag and tied to the inside of the trap. Typically I use 2-3 tent stakes to secure the trap so the little bastards can't flip the trap and escape.
My honeycrip tree had probably 60 apples on it this year. They had just started turning red and within the past week all the apples were gone.
What rifle and ammo are you using? If I have one in a trap or at close range I take them out with 22lr cci quiets. Longer distance get standard/hi velocity 22lr. My wife previously asked me why there was a bird feeder in the middle of the yard with a ribbon hanging off the bottom. I simply replied squirrels and wind indicator.
