Well the title gives it all away. The ladybugs have been eating the aphids, and the odd white fly which came home with a few mint plants I got from Richter's Herbs last week. There's still a few aphids on the tomato plants, the ladybugs don't seem to like being on the tomato plants very much but most of them are gone and the slightly damaged plants seem to be making a come back. So far it took 3 releases of ladybugs, roughly a couple hundred each time, they tend to fly away when the door and windows are opened for ventilation (except for the dead ones). Do they fly back to the place I bough them? Probably!
