|Scales don't usually bother snapdragons and they don't show up in hordes overnight so I am fairly certain you are dealing with aphids. Zillions of black bugs could be black bean aphids. These can be controlled with insecticidal soap sprays or hosed off with a strong stream of water from the hose. Good luck with your plants!
