Frankly with all the rain we've had the sooty mould would have washed off if it was going to.
The introduction of insects is impractical for most gardeners. They are either there or not and probably not at this time of year.
If you really want to get rid of it - it will harm the bay - you will have to take more drastic action. But if the bush is small and the weather sunny, you can sit down and wipe off the critters on the undersides of the leaves with warm water and washing up liquid.
It all depends on whether you are a chemical-user or not.
