Aphids on seedlings

I am raising some Geums from seed - they are currently about 3" tall and are in 3" pots on a windowsill.  Somehow they have got greenfly.  I pick the greenfly off every day and squash them, but they come back very fast.  Is there anything else I can do?  It's very hard getting at the tiny insects without crushing the fragile stems.
