@FLkeys1 - I don't think BT kills right away. You will start seeing worms hanging from strings looking lethargic and then you will find them everywhere during trim drying out. If you see one, then you have a hundred. Spray the whole garden. I hung my spring solar dried trees outside under the carport and they just kept dropping down on strings for a week as they abandoned the drying ship. Made the mistake of doing this inside the first time and ended up with strings and worms everywhere in the room!

Yep, it is still alive and I sprayed it around 7 this morn. but he is not moving and no longer eating. says here it can take a couple days. but it looks like the Caterpillar stops eating not to long after eating the BT
Bt has to be eaten to cause mortality. The
Bt toxin dissolve in the high pH insect gut and become active. The toxins then attack the gut cells of the insect, punching holes in the lining. The
Bt spores spills out of the gut and germinate in the insect causing death within a couple days.
sounds like a really bad way to die..
thanks for the info.
