Hi I was wondering if anyone knows of a homemade pest repellent to put on my veggie garden? I saw one a while back that used dish detergent,has anyone tried this or have any recipes for a good one.
I have heard of people culturing BT, but have not tried it. The principle would be the same as sourdough bread starter, you know, remove some of the starter to use, then add more food(caterpillars) to the batch. Repeat indefinately.
Ivey! You sure brought back memories! I used to gather infected caterpillars, put them in a blender and culture them in milk! It was right juicy looking! Then they started making Bt and selling it at the stores! whew!
tyedyedtc...what bugs are you dealing with in particular? there are many good recipes, some aimed at a definite bug and leaving others alone. Care to elaborate? (PS...I'm near the Raleigh-Durham area...to me we're practically neighbors!)

I mostly use a red pepper spray or diatamaceous earth, depending on the bug. Look through the Dirt Doctor site...he has been doing this for a long time and I have used a lot of his ideas that worked. However, grasshoppers are uncontrollable as far as I can tell.
Byron: Nicotine is an excellent insect killer. Better to use nicotine sulfate powder, sold at farm stores. Tobacco dust(or tea) kills 'em but can carry mosaic virus to tomatoes, eggplants, peppers, datura, petunia, etc. any Solanum. Even if you smoke in the garden, it's better not to touch tomato plants.

If you're planning to spray indoor foliage, reconsider using organic sprays that contain garlic and onion. I had a beautiful China Doll plant that was taken over by aphids. I used a tea of garlic, onions, chili and soap that was *very* diluted with water. The spray worked--killed those darn aphids but I had the plant in my bedroom and the smell was so overwhelming I had to put the little guy outside to air off. Well, the weather got to be about 100 degrees that day and the poor thing just fried. He's probably thinking he was better off with the aphids but just wanted to warn you.
I have also used tobacco tea before but instead of spraying, I used a new paintbrush to paint the tea liberally on the infected areas (mostly young shoots) and it worked great without any smells and it puts the stuff right where you want it.
Byron~ I did say it can spread that way, not it would always. All gardening is a gambling game where we do what we think will give us the best chance of getting the desired result. Tweak this here, tweak that a little over there, and hope there's no tornado, etc. to wipe out all the work. I use Tobacco on other plants, just not the solanceous. :)
