Yea I've always heard bt is safe to use right up to harvest. I only spray it every 2.5 weeks though. I've been under the impression its a bacteria that colonizes the leaf surface and any caterpillar that eats the bacteria becomes victim to it eating them from the inside out, and then respreading the BT.
I believe spinosad is similar as well, although I am a lot more guarded with spino, and only spray at night as its linked to bee colony collapse.
