Aphid control?

I wanted to save this idea, so I'm sticking it here in case anyone else is interested:

"Aphids don't like hot peppers, so grow a few extra.  If you have aphids, put 2 whole 'Serrano' peppers and one peeled garlic clove into a blender with 2-4 cups of water.  Blend well, and spray infested plants with the mixture.  If you don't have fresh peppers, cayenne boiled with garlic will make an effective 'anti-aphid' tea."

(I was going to add a photo of aphids here, but they gross me out too much.  Hate those little suckers!)
