Has anyone had to deal with yellow jackets in such high numbers that they actually become an economic problem? I have three vineyards, one of which is organic, which are getting hammered by yellow jackets. Usually they seem to come in after birds, but in these cases they are cutting into the berries themselves, and causing a lot of damage. The pickers are going to have a heck of a problem as well. I'm thinking that we're going to need to make some sort of homemade meat bait concoction, and I'd love to hear any experiences or ideas on that or some other strategy.
Any input appreciated.

I haven't had any direct experience with Vespula in grapes but certainly they'll go after sugary materials almost to the same extent as ant do, carbohydrates = energy. It will be a real challenge to find an organic material registered. Once upon a time structural PCOs could get Knox-Out, a microencapsulated diazinon from Atochem that could be mixed with tuna fish. I think it worked pretty well but don't know if it's still available. You'd have to use it in the surrounding non-crop area and then I don't know how far the yellowjackets would be attracted to it. And you'd have to check with your organic certifier as to whether they'd allow this use, even outside the vineyard. Other than that you'll have to track down the nest(s) in the ground or trees and destroy it (them). Good luck!

You could try mixing Solubor into the meat bait as a toxicant. Perhaps dissolve it with some sugar water first. Solubor is an organic fertilizer. It acts slowly enough that the wasps could bring it back to their nest.

You have to find the nests! Then a couple of hours after dusk...blast the hole with natural pyrethrum such as Pyganic ..and wear protective gear, (like an armoured suit)........no actually your going to get stung ...face that fact if you don't wear the right protective gear, talk to a bee man.... protect yourself. There are dusts such as silica dusts and natural pyrethriums such as Pyganic or Pyrenone to spray on the workers that are hovering as you smoke the nest and then seal it......They can dig to get out from the hive so saturate the nest hole with Pyretherium..........that the organic method.
There is a service in many counties.....you can to remove hives called "Hive Removal".....they can help you more with the right gear..However, your yellow jacket colony will be usually in something like a rodent burrow or tree holes, etc. This time of the year.......they will still a whole sandwich if you look the other way. They really want protein, but the sugar will sustain them as a second choice. Your problem is finding the source once you do that......kill him.
A Non-organic.......get some ether in the form of carberator cleaner (or "Wasp Freeze"......more expensive but the same thing.......
So
1.) Find the nests
2.) After dark.....kill the nest and do your best to avoid pain of free flying workers
3.) Drench the nest with pyrethrium and seal with oil or blaster of paris, dirt is not enough.
Have fun.

Steve,
In urban pest control we vacuum them out of their nests. There is a good
article in the August 2004 issue of Pest Control Technology on this. Also
Phil Boise does it, and probably Michael Baskfsky.
Knox Out is diazinon and is not available. I would think it would be much
too late in the year for these baits anyway. By the way, I have read that the
yellow traps are just for show.
Lance has good suggestions, and Drione is an excellent dust to use--you
might check to see if it is organic. I would add that on a day with clear blue
sky you can watch them flying home against the sky. For your sake I hope
there is only one massive nest.
