I went out to trim our hedge today and I noticed a lot of the small box hedge at the front of my garden has significant dieback. 

Upon closer inspection the hedge has a large amount of web type covering and small round creatures in the webbing. The RHS website shows this as box hedge caterpillar / moth, which is pretty damaging.

I’ve given the hedge a good going over with Provanto which is suggested for control of this damaging caterpillar. I’ll update my blog in a couple of weeks with the result.
