Please Help! Buggers have almost eaten it!

[Floopy21]

Came home today to find my twisted willow almost completely devoured by hundreds of hungry caterpillars. Picked as many as I could see off, but how do I get rid of the blighters? I can't do this everyday & I bet I've missed lots - along with all their eggs. Please help me to KILL! KILL!

Employ small children?

I get my dc's to pick off cabbage whites. Even the hens woon't eat them!

O, looks like a job for me then, my foetus isn't old enough to pick em off. How boring, was hoping for a magical organic spray which didn't hurt birds, etc!

B&Q sell a thing called Bugs Away or something. It is an organic pesticide that only kills the bugs not the birds, pets or children. You can but it in a spray bottle for about 4pounds. I use it on my cabbages.
