Caterpillars / BT spray

[Stickers]

Can I use BT caterpillar spray on flowers? I'm about 3-4 weeks from harvest.
I see that it's on California's list of approved pesticides. Any advice, precautions?

Newbie question but what is BT spray?

Don’t ever spray anything on flowers that’s just my advice.

Last year I used spinosad and plucked all I could find. This year the praying mantis have done the job.

I have/had a praying mantis on one of my outdoor girls. He's lived on her nearly all his life. He found her when he was tiny, now he's about 2.5-3" long.

Here's mine thats not camera shy, the others hide very well. I did move it (and another) the other day, once on my hand I tried to put it on a GG4, it said "no way dude"! So I took it to the GSC and it moved right off onto the plant.

I don't spray once my buds are into their final weeks. I walk through the garden and take long long looks at each plant now. I shake them alittle, i inspect every branch and i mean i look at it all. Unless you got " sterile grounds" you are in the bug zones growing outdoors. I'm a recreational/hobby grower only grow for ourselves. So with the legal limit of plants i can maintain decent outdoor plants and i don't grow " monsters or over 6ft " .

I wish we had mantis around, i've not seen one this year. I just have butterflies landing on my buds LOL oh and a occasional bee.

BT stands for bacillus thuringiensis but can be labeled as BT by stores. It is a bacteria that you spray on plants to get rid of caterpillars. The caterpillars eat leaves with the bacteria on it and it explodes their insides. I use it on my tomato plants but have never had to use on cannabis.

The 40 acre outdoor commercial grow next to me puts these out, and ladybugs, they come here and I am glad to have them!
Next year should be even better!
