We have a few products approved for organic gardening that you can use on vegetables. Our two big sellers is the MULTIPURPOSE INSECT KILLER and the 3 IN1 CONCENTRATE. If you have nothing but insects to kill, go with the Multipurpose because it will handle anything. You can treat as often as is needed but most people find once a week is enough and less often as the season grows late in the summer and fall.

The 3 In 1 has more actives including a fungicide and spreader sticker so it's a more complete spray. Use this concentrate if you're dealing with a wide range of pests but also plant fungus.

Both products are approved for organic gardening and will dissipate within a day or two of being applied so they pose little to no hazard when used on plants that will generate some kind of fruit or vegetable.

The CYPERMETHRIN listed in our CICADA KILLER CONTROL would not be the best option for this application need. Though I don't think the concentrate would be absorbed by the plant enough to pose a hazard, in general this active is not for use on plants that produce fruit or vegetables. Due to the close proximity of the treatment, I suggest opting for something else. Alternatively there are some organic or less toxic products we have which will work fine and still be safe to use around and even on the plants if needed.

The most direct approach would to wait till dark and then dust their open holes with CONCERN DE DUST. Apply it with a HAND DUSTER and you'll get instant control of any wasps in the nest when you dust. In theory you should be able to treat all the nests you have heavily enough to shut them down within minutes of the treatment.

Alternatively you could opt to spray some MULTI PURPOSE INSECT KILLER directly down their nests. If done in the evening when you know they'll be back for the night, the treatment will kill them all on contact as it's poured or sprayed down their nest. In general, if you're thorough enough the first time you treat and carefully get each burrow, you can knock them all out with one application. But if you have 5 or more nests, it will probably take a couple of treatments since they can sometimes hide well or some peripheral nests can be missed.

There are several organic options that are made for garden plants. The two most common include the GARDEN DEFENSE WITH NEEM and the 3 IN ONE CONCENTRATE. Both of these have a short one day to harvest wait period which means you can spray either right up to the day before you intend on picking your fruit or vegetable since their residual is so safe and short lived.

As for the difference between the two; the Neem is highly active on most insects and tends to repel them for up to a week. It's really just for insect control where as the 3 in 1 has both a Miticide and a Fungicide included so it covers more problems common to the garden. Use it if you find either to be an issue during the garden growing season.
