The most commonly used strain of Bt (kurstaki strain) will kill only leaf- and needle-feeding caterpillars.

I am really rooting for you @
CannaCrone , and everyone else for that matter!
What is interesting to me, is like you CannaCrone, I also have more than one spot. And many strains, a few from others. And I only had them on a few certain girls...
Folks like to say what they heard or read, so you know, according to what everyone thinks they know we got these from not being clean, or taking cuts from a club or a well meaning friend.
I call bullshit on that, sure maybe sometimes that is the case. But it is NOT how I got them, I don't know what brought them in but it isnt that.
I have scoped many gardens and all of my stuff, and mine was localized to a few plants in particular with little to no probability that I got the bugs from a club, or a friend, or the soil, etc...
those few girls I had that did get them, were right next to where the god damned deer was crawling under the fence and brushing up against them pretty heavily....Do I have to catch one of those damned deer and sample their fur?? I just may do that!
