We have a large bay laurel in our garden that was there when we moved in. It’s next to our gazebo and this year we have noticed a lot of wasps. After googling I can see it’s swarming with bay suckers. The online information about dealing with this tends to assume a mild infestation or a small bush, but ours is very large and is covered in them. Is there anything we can do? The ladybirds are having a feast, but it’s too much for even them to munch through.
