declining of our palm trees

Those pesky giant red palm weevils are demolishing our palm trees! :( Dammit. Found a few of those beetles on the grass near the trees.
Finding contractors to eradicate them. The first company was very irresponsible. I have to make countless reminders for her (and she is the director somemore) to send the quotations. How difficult can that be? We gave up and finally turn to Arbor culture. Hope they revert asap. It is quite interesting how the process will be. We need to cut some of them down and probably require strong chemicals. Hope they won't hurt the nearby wildlife and our animals. :/
