How do you get the underside of the leaves where most bugs and
catipillars like to hide?


Well, with that kind of product, I couldn't. That shouldn't matter
with a BT product. Since it doesn't kill by contact, you don't have
to get it on the hiding caterpillars. You just have to put it where
they will eat it. I was trying to kill cabbage worms and they eat a
hole right through the leaf. Coverage of the upper surface would do it.
As I said, it didn't work. Perhaps it was old, perhaps it had too
low a concentration from the beginning. Maybe enough didn't stick to
the leaves to do the job. Dipel mixed with water and sprayed on
works every time.
