Sounds more like aphids - use neem oil, insecticidal soap or pyrethrum. Try to hit the bugs directly with whatever you spray (top and bottom of leaves). Check them each day and do follow-up spraying if needed. Should take less than a week to eradicate them.
Of course, you can use what you want and may not have access/funds to get something else, but I wouldn't spray that on my plants, unless I tried everything else it wasn't working. If you can, go to your local garden store and buy some insecticidal soap - should cost less than $10. In my opinion, neem oil is the best, but can be hard to find (unless you go to a nursery) and most likely will be concentrated, which means you'll need an spay bottle as well. You can get those at your local drug store (Rite Aid).
