A constant battle for last month!

Hey guys here we have my outdoor stardawg plant she's now been indoors about a month and half under a 600whps but for the last month I keep finding these little fucking catterpilas I keep taking them off its been a month now and I still find the odd little one. I can't buy bt spray in the UK it's illegal for some unknown reason to me.. Can anyone tell me any spray I can buy local... I'd say she has 2 to 3weeks left? as some of the pistols are turning but as you can see by the pictures a month has gone by and I've never found them on any other branches apart from the bottom 3 it's really pissing me off stressing my girl out aswell.


I should of acted a month ago I know but I thought I'd just keep taking them off as i only found the odd ones fucking stupid I know.

Anyone?????

Diatomaceous earth might work for the pots and a bit of mulch maybe. I haven't a clue for up top. You might just have to be really vigilant.

I'm in the UK there is sprays available, I've got one for fruiting and flowing plant, speak to your grow shop.

For future reference i've used h202 17.5% 50ml per litre in the past but on vegging plants I don't think I'd used it on a flowering plant.
You could also use a smoke bomb to kill them, it's also needs a wetting agent so insects can't maintain a bubble around them!
