10 days into flower and preventing caterpillars with BT/Neem Oil [PICS]

What's up people! I am about 10 days into flowering with a Barney Farm LSD. My previous plant that was right next to it was an auto. This auto during the drying phase ended up having a TON of caterpillars. I ended up tossing the batch. I took no preventive measures and didn't see ANY signs of caterpillars through out the budding staging. Even through trimming I didn't notice anything.

However, I am hoping I can prevent this from happening on my 2nd baby. It is about 10 days in and has small buds forming. I've sprayed BT 2 nights in a row. I have not seen, or noticed any bugs or insects, but I don't trust my insight. I only found 1 leaf with a couple holes that's it.

I just want to be extra cautious so I just prepared some neem oil mix and want to also spray the plant down with some neem oil.

I have BT, and I have Neem Oil. I just need some real insight into how often should I use these formulas. When is too late to use it. I've read so much back and forth, but I am trying to find some real insight. What other steps can I take here?

Whatever layed the eggs that turned into caterpillars is probably gone.

If your plant has started flowering, i would be careful with spraying.

I say watch it closely and only use spray if it is 100% sure you need them - And if you do, avoid spraying generally and target only fan leaves as closely as possible.

If it is just a preventive measure, i would say do not spray the plant with flowers already on.

As you can see the buds were nice with hair in the beginning and after all this time i've seen them bulk, but the hairs are dead or non existent. Check it out
