| Blackfly look a bit like black versions of greenfly! http://www.gardenaction.co.uk/techni...sts/aphids.htm Bit of info there for you! Greenfly on the window sill? Yep I get that on my basil plants in the kitchen from time to time. I run the plants under the tap and smudge them off. I'm reluctant to use soapy water on stuff I'm going to eat, although that would be my 2nd method of choice! |

| Are your greenfly on plants or seedlings?? If it's on seedlings then it is more of a problem as they are so much more delicate. I wonder if it's worth buying those yellow sticky strips and chop them into smaller pieces to prevent them spreading to other plants? Cotton bud and soapy water for seedlings I think! Have a good holiday, I'm sure they'll be fine!!!  |

| You'll kinow blackfly when you get it!! Same as greenfly but different colour. They love new shoots and reproduce so fast that the shoots in question are totally covered in black (or green) aphids. You can either squash them (effective but messy), spray them with soapy water (sort of effective) or spray them with insecticide (effective but not to everyone's principles) |

| I had blackfly on my broad beans last year (btw it's recommended to nip the succulent tops out as its these they go for) anyway............. My blackfly was cured organically by ants!!! They were in a convoy running up the plants, grabbing a blackfly and running down again with said blackfly in mandibles! They ate the lot!!!! Consequently when I have been doing the winter digging I have been very careful not to damage any ants nests!
