Check around your garden. there is probably a host colony on something else. get rid of that and you will most likely will get rid of your problem. that said, scout around for ladybugs or order some. they are the BEST way to control aphids. I get them ladybugs every year for my greenhouse because there seems to never be a great way to keep them out. one tiny colony on a weed or other plant will make for a huge issue within a week or two.

I'd just spray them with water anyway, unless you have high humidity and are worried about disease. Make sure you use a shower nozzle rather than just spraying with your finger on the hose or something. I don't think being sprayed off is the reason showering plants gets rid of the aphids, personally. I'm not really sure what the reason is, but whether the aphids get sprayed off or not, it still has helped when I've done it and repeated the process every two or three days for a while.
Alternatively, I know it's not supposed to be a pesticide (but rather a fertilizer), but doing a foliar spray with calcium nitrate (one time) got rid of a heavy aphid infestation on my peppers in 2015. They didn't like it and they disappeared. They were a fast-breeding and fast-moving kind that looked pretty tough. Ladybugs didn't seem to mind the fertilizer.

What dilution of the calcium nitrate do you use Zebi? I have a bunch of Ca(NO3)2 to use in SIPs, to give the plants the so called snacks. Helps tomatoes get the Ca, to avoid, or reduce the amount of BER. I just did that to the SIPs today, with a little epsom salts added, as well.

pepperhead212 , I don't remember, but it was probably the recommended amount, and it seemed a normal amount (it didn't burn the peppers). I got it from greenwaybiotech.com. It's a prilled kind. The website says this: "Foliar Application: Mix 2-4 tablespoons per 1 gallon of water and spray the leaves with it." 4 tablespoons sounds like a lot. I probably did less. Here's the direct link to it (I got 10lbs and have been very conservative with it): www.greenwaybiotech.com/products/calcium-nitrate

Zebi,Yeah, I got 10 lbs of it on ebay way back, and only use a small amount at a time. I figured about 1 tb to a gal, since I remember that being recommended for a foliar spray for tomatoes, as a Ca supplement, though I never did that. If I see any more aphids on the tomatoes, okra, or peppers, I'll try it. Thanks.
