I have realised for some time that something is eating the leaves of my lovely bay tree, but it wasn't until just now when I had my glasses on that I realised how bad the problem actually is. The branches are plastered with little flat beetle-like insects, and I mean, really plastered. They are about 3mm long and don't actually seem to move, thank goodness! I suppose I will have to buy some kind of insect killer from the garden centre but I hate using insecticides and wonder if I may have left it too late. Any ideas please?
