Thanks Charlie for the suggestion. I can imagine brushing them off to be a right game as they are so small and the bushes very dense so getting into the heart of the bush to try and spot them a task and a half! The other problem that I see is once the bush (say we could do it by hand) is cleared of these minute beetles is that we are then left with a devastated viburnum and obviously would need to trim back possibly hard prune so the bush can give new growth which will be unspoilt by yet more beetle so to me it looks like it could well be a loosing battle and perhaps the best thing to do is dig it up and replace it. I'll bear your suggestion in mind, just wonder if anyone else has had any success with dealing with this?
I could be wrong but even if I started using sprays to fight off the beetles, all I'm doing is continuously throwing money at it and client would be better off in the long run just purchasing something else to replace it/them!!
Cheers in advance if any of you managed to overcome the problem and could let us know!
