I'd rather take on all the deer on the block than mess with aphids. Hate the critters. All the natural sprays only work so long then bingo they are back. Corn have them again. Don't have much luck with ladybugs either.
Jeez, don't mention ladybugs, it reminds me that the fall ladybeetle season is coming. We get thousands of the invasive nasties swarming into the house and barns in October. I use a shop vac to suck them up. They stink, bite, stain the walls and furniture with their secretions and make the cats sick when they eat them. Another failed experiment with a foreign biological "solution" to a perceived local problem. Sorry, one of my peeves!
