Ants and vinca

One of my Titan vinca seedlings–still planter box squatting–bloomed this morning: a pale pink with rosy center. But where are all these blasted black ants coming from? They seem to favor the vinca and are chewing tiny holes into them–all of them! I’m readying the spreader to drop the insect-killer on them!
