I'm assuming that the chemical type sprays you can buy would be too harsh? They are on some indoor chilli plants, the flowering part of a Venus fly trap and even some bought cut flowers . How did the critters get there, just through an open window or whatever?!
How weird I was just about to post pretty much the self same thing, so will be watching for tips too
We have peppers growing in DDs window & they were doing well, but they are now covered in the damned things - aphids that look like greenfly, though as there are a few blackfly around the window too I think they might actually be blackfly
I have been looking out for ladybirds in the hope that putting some of those on the plants, they will eat them all, but not seen a ladybird sinceAlso very puzzled as to how they got there, DDs window is kept closed due to noise, so even more of a mystery
I have this problem too - I think they just fly in through the open windows - it only takes 1 greenfly to give birth to 1000s of babies. I take my houseplants outside and spray them with the fat based organic spray which isn't harsh at all and makes their leaves nice and shiny - would work on a pepper but I'd avoid getting any on the fruit if poss. Mind you squishing them by hand is very satisfying and quite effective if only 1 or 2 plants..?
