Help. Late Season Bud Worm Infestation

Hello,

I own an outdoor rec grow in Colorado and have a little over 1000 plants. Everything was going great until about 10 days ago I noticed a rotten looking bud. After searching more, I found a caterpillar had eaten the middle of the bud.

Now they are showing up everywhere. I sprayed BT, and used an organic pest repellent with garlic and neem oil. The BT killed some but I'm still finding 5-6 bud worms on every plant. I've hand killed thousands already.

Is there any other trick to stop these things? I know these moths lay the eggs and then they hatch into caterpillars/Bud Worms.

Being outdoor, I think we could go another month before harvest. just hit 12/12 sunlight 3 days ago. If I harvest now, I will cut self short and if I harvest later the worms could kill my product. Its like a lose lose.

Bump...

Anyone else ever had this issue?

try monteray spinnosad or bt

2 of my plants had bud worms and the green catapillars, didn't notice them until a week and a half before my harvest. I kept picking them off by hand every other day until it was time. I still have one more plant growing that's about 5 to 6 weeks into flower and I sprayed it with Monterey bt. Next day found a bud worm hanging from a branch. I will continue to spray every 5 days until 2 weeks before harvest. But with your size operation I would use some kind of fogger
