Just before lights out would be best and you can douche it daily. Once you knock em back a bit then get on the weekly regimen: spray with peroxide, wait 48 hours, spray with Captain Jack’s, wait 5 days, repeat.
Sorry have been away this week for work - ripening buds being the main issue I would probably try lady bugs from amazon. Pretty reasonable and with the amount you get per order you should see instant results and as long as they stay alive they’ll keep the white flies at bay.
Hydrogen peroxide and a peppermint/chrysanthemum spray have greatly reduced the infestation.
However, seems there are still a few around.
I will continue the spray treatment until next week when I harvest.
Then…everything gets sterilized and sanitized.
All the helpful suggestions have been a great help…thanks to all.
I just killed a bunch of them on my plants. Not just the ladies, I grow a lot of tomatoes which got attacked by white flies every year for 3 decades. On all veggies too, so I found way to kill them organically that I don’t have to worry eating them.
No, don’t use been oil on it! Here’re faith of white flies that fed on my tomatoes. (I didn’t have them as much on my weed because I babied them with spray more often). I neglected them too much because I spent most of my time on my weeds, some had snapped. So I quickly pounded up 5 garlic cloves + 2 hanenero peppers, and added 1/2 tsp of Dawn liquid dishwasher. Strained into spray bottle. Dead on contact!
