Box tree problem

Hi, I have been away for 5 weeks on my return i find my Box hedge is covered with a white powder like substance and little webs all over. Can anyone tell me what this may be and how do I eradicate it please
Regards John

 

Hi John,

A few photos of the tree will help us deal with your enquiry better if that's possible at all? It sounds like a number of things including mildew, mould or insect infestation.

 

It sounds like woolly aphid, something I've not come across on Box before but now have a small infestation. This has been discussed already on another thread:

You'll end up with caterpillars, they infest the father in laws, bloody horrible things, the hedge looks like it's alive :(
