Oh my Alec, that is a first for this forum, I did write about the dreaded Red Weevil on our gardening blog - our post is here
http://gardeningspain.blogspot.com/2008/04/red-weevil-in-spanish-palm-trees.htmlThanks for telling us about your endeavours and so sorry to hear you have been infected, I was not aware of there being a cure and I will certainly be remembering this post for the future.
Liz is right in saying that it is a job for the council and I even heard that we have to register our palm trees now with our local town halls, however, I am not so sure about that - we have about 18 different variations of palm trees and I pray every day that my large palm tree doesn't suffer, I would cry if that had to go

Fingers crossed for you buddy
