Something's eating my sanguinea!!!

Help!!! Does anyone know what the little caterpillary things are that are going after my brugs? I squashed what I could find - they eat the green out and leave kind of a grey transparent spot. Is there anything I can use to get rid of them? Looks like they have just started.
Please help!!!

Thanks KHT - if I Raid them is that it or do they just keep coming all summer? Are these moth caterpillars I'm looking at?
Thanks again - Liz

Hasn't anyone else tried Volck Oil Spray? Someone, somewhere suggested it last year (had spider mites, even outdoors! which is a first for me, well, outdoors, anyway!) I used that product and it got rid of the spider mites, kept them at bay for about a month and a half, and kept all other pests away, also!

Nan,
I have not tried Volck oil or neem oil, but I am hearing enough rave reviews with Brugmansia growers that I think I am going to give both of them a try.
Brugmansia

Brugmansia...I haven't tried the Neem oil either, but have also heard lots of great things about it. The Volck Oil works fantastically though...and it's very easy to get (if I can get it here, anyone can!) I did finally find a nursery nearby that has the Neem Oil...I may try it too. You'll be pleased with the results of the Volck Oil...I just mix it in a hand-operated mist sprayer. Kept *all* pests away from mine last year!
