Fill your spray bottle with water, add about a tablespoon, maybe a little more of joy. Get in close when you spray & spray them good. Most bug hate lemon, but the soap disoves any waxy coating on insects & makes it easier to drown them, plus the lemon helps repel others around the plants, & they don't like the taste of soap either. This works with aphids too. Shake the excess off, & do this daily untill you don't see any more. You'll only need to break out the big guns (insecticide) if you have a heavy infestation. Safer products make an insecticidal soap I'd try before going to the hard stuff if you're infested.
