Just a heads up to anyone that deals with box and like me thought Box tree caterpillar was confined to london and the south east.
It appears this years weather has provided perfect breeding.
Here is a current map of outbreaks recorded -- a massive increase this year and considering many wont list their outbreak you can assume that pretty much most of the UK now has populations in their area.
Ive read the life cycle of the Moth is 6-8 weeks and that we are now enetring the 3rd life cycle of this year -- with a mild autumn possibly ahead, we could see the current caterpillars turn into moths and have a final breeding.

Really important to take some time inspecting any box you deal with -- early signs are very easy to miss - but much easier to deal with if you catch them now and get them done before another cycle is complete and winter comes.
Picture showing early signs -- look for bite marks or the light coloured wavy remains of a leaf stem. Caterpillar will probably be inside - possibly within a webbing -- as this is spider time of year theres a lot of webbing around which may not be caterpillar
