Black ant is the common name for field ants. They are harmless and do not cause any specific damage to property, livestock or humans. When they infest homes, they can become a nuisance as they travel across feeding areas foraging for food.

Pest Control Tips for dealing with Black ants -

As with other types of ants, it's important to avoid direct spraying or other forms of direct application of pesticide. The best method of dealing with an infestation of black ants is using slow-action bait.

You should bait the ant trails and allow the foraging workers time to bring the bait inside the nests. It could take several weeks for this pest control technique to reach full effect.
