I was looking for a homemade remedy to keep the bad insects away from my vegetable plants. I noticed some aphids on my tomatoes, and the ladybugs can't seem to eat them fast enough.
I saw something on TV once made with hot peppers blended with other stuff, but I can't remember. I'd like to stay organic and food-safe without having to buy a pesticide (don't want to harm the ladybugs-just repel the "bad guys").
Hmm, I've heard about the pepper recipe, but I have no idea if it works!
A website that I use A LOT is from the University of California, Davis. They have a wonderful website with ideas on how to non or least-toxically get rid of, or better yet, prevent, pests.

First things first though! Basic Integrated Pest Management (IPM) says that you need to know what you are trying to get rid of first. As far as aphids, the website has a bunch of wonderful ideas. I find that insecticidal soap works very well, which you can make yourself using soap and water (recipe: http://azaz.essortment.com/homemadeinsec_rvhp.htm ). You can also blast them off with the hose.
http://ipm.ucdavis.edu/PMG/PESTNOTES/pn7404.html is the specific stuff about aphids and you have many options to choose from. Sometimes, if the aphids aren't doing a lot of damage too, who cares if they eat a bit!
Anywho, good luck!
