Why oh why oh why oh why is it so hard to get rid of aphids on Chilli plants? Time and time again I take them out the windowsill, clean the windowsill, hoover and give them a good washing down with soapy water mixed with a bit of neem oil and peppermint oil. I then water the plant with a little neem oil in water as well as Rhubarb leaf tea (a god insecticide) AND still a couple of days later they are as rampant with their sticky residue on the window glass (how it gets there is a mystery)
I repeat the process over and over to no avail. I just give up as technically they should have died off against the odds.
