are this little one Leaf lice?

Looks like black aphids and some sort of predator fly. maybe a lacewing as they eat aphids. Most aphids can be blasted off with a jet of water from the hose they don't latch on to hard. Do this in an area where they fall off they can't easily walk back to the plant, Then apply a soapy water mixture, let it sit on for a few min and rinse off, dry plant in the shade and the bugs will be gone. They can come back but hopefully not in any crazy numbers. Pesticide is also an option but I don't like that when its starting to enter flower. predatory bugs are also good, but when the plants get super sticky they can also get stuck in them. Good Luck!
