Killing caterpillars without BT?

San Diego, CA(Zone 10b)

What's the best way to treat for catterpillars if the plant in question is waaay to large to spray with Bt? My brugmansia is over 10ft tall there is no way I can spray the whole thing. It's suffering a major attack with holes everywhere...
Thanks!

don't you have a hose-end sprayer (like the dial-n-spray)? i do my whole yard with that sprayer (for feed, bt, neem, you name it) it will reach a lot farther than 10 feet.

I don't have one, but I WILL tomorrow! lol! How come I never thought of it, thank you so much! I didn't know it was OK to use the same sprayer for everything either. Thanks!!!!
