if it is codling moth, then you can do a few things. the foot sox is a good option for dwarf and super dwarf trees for sure. timing is important, so check local extension office to see when moths are emerging. it is temperature dependent.
you can use a mating disruptor, easy enough to find and buy, which tricks the moths into landing on sticky cards with tanglefoot on them.
I don't recommend biocides, because they are not always pest specific and harm people and animals.
kaolin clay: look up the product called Surround, it is a super refined clay that pisses off all kinds of bug oviposition and feeding behavior and won't harm people or animals. it works for other fruit tree pests as well.
go through your fruit trees and thin out any that look damaged, stung, dimpled, scabbed etc. this will make for bigger fruit when you harvest.
pick up dropped fruit or let the chickens go through and eat them.
good luck.
