The bay leaf sucker problem was fantastic. I've never heard of them before and having searched the internet and even been down to my local nursery (who couldn't identify the pest) I fell on this article by accident. I've picked off all the affected leaves and sprayed the rest of the bay tree with Bayer "Provado" which contains thiacloprid as recommended by you. Fingers crossed!
