Dealing (Organically) with Caterpillars on Brussells Sprouts

[al]

I've just dusted with DERRIS powder some brussells sprouts plants suffering a caterpillar infestation.

Are there any alternative organic methods for dealing with caterpillars ?

The ultimate organic method for dealing with caterpillers is to remove them by hand one by one!!!!!

Even better is to get some kids from the neighborhood to do it for you!!!! Tell them they are better than worms for fishing!!!!

Bt-K in particular.

caterpillar infestation.

Floating row covers to prevent egg deposition. Hand picking. BT which is a bacterial control for the larvae of Moths and Butterflies and sold as Dipel or Thuricide in many places. It works best when applied early.
