Black Vine Weevil - Grrrrrrrrrrrrrrrrrrrr

About four years ago, I discovered that the dreaded weevil had made a home in our azaleas. I have tried every organic remedy that I could find, by appropriate season. I knew that I had not eradicated them, but I seem to have slowed the spread.

We have lost one azalea, and two more seem to be getting smaller every year. I now find that they have spread in the opposite direction and made a home with the new Otto Luyken.

I am ready to bring in the big guns...chemicals!

Can anyone who has had success with chemicals, please offer me some advice? Which chemicals/which brands? If I irradiate them in one area, will they simple spread to another? How much of an area do I need to treat? Is there any value to using Grub Ex (imidaclropld) in the bed or surrounding lawn?

This is absolutely breaking my heart. I would be so grateful for some wisdom.

The timing of your treatments is essential with weevils and in checking GrubEx, while it may have been helpful, seems you have missed the boat so to speak.:) Grub/larvae control should have taken place before Aug 1 with GrubEx if I'm reading the product correctly. Much the same with treating adults before they've laid eggs - that's been accomplished by late August too. You may not solve your problem this year, other than reducing adults to minimize any more notched foliage.
