I don't know if it will work where Lucky is but I always use concentrated apple juice in wasp traps to get adequate control, but it takes a lot of traps- probably 6-8 for a tree of that size. We do get years where they swarm the entire lawn area but I still get my fruit. Most of the commercial traps come with a bait. As long as they require adding water to that bait you can replace their bait with a 1-3 ratio concentrate to water. Add citric acid to delay the turn to vinegar.

they arent STILL bare root are they??? if you can NOT ID any damage.. then nothing need be done ... i presume they are not fruiting.. as recent transplants.. so there is NOTHING to protect ... we NEVER spray prophylactically ... first you ID the pest .. then you decide if it is beneficial.. then you prevent it.. if necessary ... there is a fruit forum.. and they do things different than tree peeps .... but no one should be recommending preventive spraying on a new tree ... as it should have no fruit.. your only goal for at least 1 to 2 years.. is to make it live .. and grow the roots necessary to sustain your future crop producing abilities ... and basically .... in my world.. that means WATER PROPERLY ,... ken

Been trying to identify the original. been paying close attention to it characteristics ect this year. Have someone coming to try and ID from a local fruit association. this tree is our family tree so I'm positive it had not been previously grafted (before this year). it was pretty large in the spring so wanted to leave a few branches to nurse the rootsystem. It's a vigorous tree. I have grafted to rootstock with a rosey glow scion which is an early ripening sport of pink lady. Very interested to see if it produces apples close to the original tree

Honestly, you might be better just pulling it out and planting a known apple. Who knows what rootstock you have, could range from a super dwarf m26 (unlikley) that will never get taller than 7' up to a seedling rootstock (unlikley) that will be 40'+. And the apples are probably some commercial variety that needs a ton of spraying to stay healthy and provide any fruit. Instead get a rootstock that will do well in your climate, with your disease pressure and that will be a size you will be happy with. Then make sure your apples are a disease resistant variety. Make sure that the 2 will flower at close to the same time (less important if you have flowering crabs in your area) because apples need another variety to cross polinate. It is also nice to have 2 different ripening times so you are not overloaded with apples at one time then get nothing for the rest of the season. Early apples such as Pristine, Redfree, Williams pride. Mid season like Crimson Crisp, Liberty, Macfree, ect. Late season like Enterprise, Goldrush, ect. Although you are in zone 8 so warmer climate guys could probably direct you to better apples for you (i'm in zone 4). Since it is just going to be 2 trees and in your backyard read about ''bagging'' apples. Can work well for spray free fruit. Good luck!
