Hi all. I don't know if anyone else is having a crisis with these foreign invaders but we are currently watching our beautiful box hedges being rapidly destroyed by these very hungry caterpillars. The hedges have gone from beautiful green to brown in the matter of days. I noticed my neighbours are also having the same problem. They are almost impossible to stop and I have tried powerhosing the hedges with some success (it removed most of them) but within 12 hours they were back again with a vengeance. It is heartbreaking to watch and couldn't have come at a worse time as we are trying to sell our house. I would be interested to hear if anyone has encountered these pests and had any luck in saving their hedges. I have read that the moths that these caterpillars turn into have managed to reach London by flying over the channel. Even Monty Don has watched his beautiful garden hedges being destroyed. This could be the end for our lovely sculpted hedges.
