Wow, haven't heard of that. But there are dusting powders to deal with caterpillars.
Generally if you encourage ladybirds around your hop garden you'll have little problems with other bugs.

(or soap) That's a common enough way to kill all aphids, i.e. by drowning. If you've a lot of plants it really helps if you spray the solution when it's raining. Not keen on it myself unless as a last resort as can kill a lot of the good bugs (e.g. ladybirds) aswell.

DE will "cut up" most any tissue it comes in contact with including your lungs.
I think this is a pretty good option for me, thanks!
