Dipel. It's actually a naturally occurring bacteria that attacks caterpillars.

Or are you just worried that they *will*? Or are they spitfires? If you can
live without using Dipel, I would try -- wasps and dragonflies ilke eating
caterpillars, and you could get something interesting when the caterpillars
turn into butterflies.

Each spring we get little green caterpillers that strip every
leaf off our bouganvilleas - and we have about 30m of bouganvillea
along our fence. Doesn't seem to do them any harm. Not sure what
the attraction is, bouganvillea leaf doesn't look particularly
tasty to me.
