Another yellow jacket question and some advice.
I have an Italian plum tree no fruit this year yet. The yellow jackets and black hornets swarm this tree. They are concentrated on this tree only. The tree is in grave danger of a madman with a chainsaw, "me." I put out the bottle of honey syrup water and am waiting. Calling local garden shop for advice. I have found by chance however that the orange cleaner is oil based and kills yellow jackets as well as any chemical spray. Any suggestions on the Italian plum tree my wife wants it to live but my chain saw is hungry.
