Box plant leaves being eaten

Justagardener

My box hedges and plants suffered from a terrible attack of Box tree catepillar this year. Did anyone else suffer from the pest this year?

I had a bad case of box blight and after that big problems with box caterpillar, with the caterpillars at least you can look for them and pull them off and the leaves grow back.

One plant had 30 catepillars on! It was almost eaten bare in one week. As you say though, at least the leaves grow back.
