I think Regina and I are on the same wavelength. I noticed these three recipes from the June/July 2008 Organic Gardening issue and wanted to pass them along to readers. Great for a small patio or backyard garden - and hot peppers are a big part of them.
Yes, the recipes are stinky - and you will have to put aside some time to prepare and make them. But a little time investment now and you could make a spray that can be used all season, keeps the bugs/pests away and is not harmful to your health...

How-to: mash/chop leaves and let leaves steep overnight in 2 cups water. Strain leaves and add another 2 cups water.

The author advises to test the spray first on a leaf to make sure it is not too strong for the plant. If the leaf looks fine after a day then it's safe to spray away. I used a version of the first one last year and it worked like a charm to keep bugs off the plants, just had to make sure to keep it off my own hands.
