Our box hedges are being decimated by box hedge caterpillars. I could cry 😟
You can see where one side of the hedge has been destroyed and they're working they're way through to the other side. It's like watching a slo-mo animation. It's gone beyond picking off the caterpillars or treating them as there are so many of them, and so much hedge. The hedge is looking dead on the side they've eaten, right through to halfway through the depth of it,
I think the only option is to rip them out and start again but are they likely to return to the same spot or is it likely that some eggs would be left lying on the ground or nearby ready to hatch and start munching again?
Are there any alternatives that won't get eaten? They're not high hedges but I need to grow something between knee and hip height to define areas along a path etc
