Alright, in the end I used a chemical to kill the whiteflies None of the 'natural remedies' on the internet worked at all. Not the potassium soap, nor the colored traps, nor the garlic with fermented cigars — nothing, nothing, nothing. Does anyone actually test these tricks, or do they just do them for the clicks? I think both. Now my lemon tree is free of those little flies, all thanks to science. Say no to garden homeopathy. Long live dimethoate!
“War Pigs” by Black Sabbath, a true marvel. Enjoy it!
