Recently I've had an increasing problem with stinkbugs, especially on my okra. I pick them and squish but there are more and more and I can't be out pickin' and squishin' all day.
I was over on the tomato forum and found this suggestion in a Stinkbug Remedies Thread.
If you seriously want to do something organic to minimize stinkbugs, you could do several of the following (all approved by usda as organic):
1. Floating row covers
2. Pyrethrin spray or dust
3. Pick the ones you can catch and drop into a can or bucket with a little rubbing alcohol (especially the wintergreen kind)
4. Watch for the red egg clusters and pick those
5. Spray the ones you see with Organic Gardening's recipe: Two cups water, one cup rubbing alcohol, one tablespoon neem oil (or veg oil), one tablespoon liquid soap (like Dr Bronners, not dish detergent), 25-30 drops of mint oil or cinnamon oil (or both). Shake well and spray on bugs with a hand sprayer (not a hose). This will kill all bugs and caterpillars upon contact, even Japanese beetles and grasshoppers.
6. I know Bigdaddy doesn't want a bait crop, but for the rest of you readers, I have found them to be very effective. My favorite is to plant Crowder Peas (Field Peas) across the garden from my tomatoes. Not only do the stinkbugs love them but they are also extremely heat hardy and drought hardy, and will produce a crop of peas for you, stinkbugs notwithstanding. I use the peas as a magnet, then spray them with the mint spray every few days. Works like a charm!
I thought I would run this past our friends here on the Oklahoma Forum, as I'm not sure how reliable info from the Tomato Forum is (after all some of those folks over there are 'Yankees')
I was especially interested in the Organic Gardening's Recipe mentioned. Does any of y'all have any experience with this mix and if so does it only kill on contact or will it repel them from returning?
