Hi Verdun, I did and do exactly the same as you! If I do miss one first time and it does it's trick of falling to the ground and lying on it's back I give the ground around the plant a quick spray of insecticide.
Green Magpie, I wondered the same as you when I first planted lilies. Now I have a bit more gardening experience I've learnt that whatever you plant it will attract whatever feeds on it. I planted roses, they got greenfly, I planted Philadelphus, that got blackfly, I planted primulas/primroses and caterpillars decimated some of them, etc, etc.
Now I plant nasturtiums to attract the blackfly away from other plants, spray some plants with insecticide and spend a lot of time checking for caterpillars.
