Default Biological control of caterpillars

The message
from "Cerumen" contains these words:

I wouldn't dream of applying any chemicals to potential food. You may
as well spoon it in and see what happens!


The biological control I use is not a "chemical" but a natural bacillus
(thuringiensis?) that is fatal to the caterpillars of cabbage butterflies
and is approved by various organic bodies for use as such.

This is the control I meant so thanks for your and Gary's input.

It seems from what Gary says that you have to spray quite carefully,
directing the spray at the caterpillars or potential caterpillars rather
than just vaguely at the plant. I'm thinking this will be just about as
time-consuming as squishing, with perhaps almost as many missed!
