i planted 2 dwarf cherry trres last year, they started buding earl then we had a late frost, so theres no cherrys.. the trees was growing greet untill i nosted some beeetal bugs on one.. i sprayed with dormant spray but they come back, there is now tiny holes in some leaves.. this is only on one tree.. the other cherry, and apple trees have no sign of bugs, the appple trres have apples on some.. any help to rid these bugs... they kind of look like a cocker roach and same size..
