Hi sotongeoff
You are so right about the wings
lol
I know wasps are part of the garden eco system but I have an awful fear of them plus my two wee grandkids potter in the garden and I'm scared the wasps could swarm if disturbed near this tree. I've heard of the jar thing but was reluctant to use it, partly because of my grandkids. I know there is a product that can be bought online (don't want to use the product name) that essentially 'fools' the wasps into thinking there's another nest nearby - apparently they won't go within a certain radius of another nest. I may give that a go 
It does look as if the tree is throwing up suckers - I will try to manage them but know I may have to speak to the neighbour if it gets worse. Yes, it can be awkward and they aren't the most pleasant at the best of times !
Anyway, thank you so much for your reply - I thought I was being silly about the suckers - I honestly didn't think a fruit tree would do that
