Help!! Outdoor grow ants under plants in soil

Hello
Started an outdoor grow about 7 days old leave are huge already and looks really healthy, Its planted in the ground in Volcanic Soil.
I have an issue thought that im really worried about, There are black ants all up in the soil now and i went to water today and they had a whole dug
right underneath the plant, Are they harming it or do they just want the water??
Also if i need to transplant it and put it into a pot, How would i do this and not have the ants in the soil???

use an ant repellent. there are several different ones and easily found. u can use the granules and even keep it well away from the plant. GL

hot peppers for pizza will help tell you get the right stuff. borox and sugar and becon grease.http://tipnut.com/ant-killer/

Are they cruising up the stems? If they are then I could check for aphids if so. either way it should be an easy fix
