You just need to take precautions if your colony is in a setup that the Argentines can slip into, like a pencil case. My colony lived for a year safely in my closet, but once I moved them onto my shelf five feet away the Argentines that lived there killed them off within a day. If your colony is away from their trails and food sources, and if you keep your ant area clean of any food, they have a much lower chance of being attacked. I've seen examples of fluon or moats being used to keep out the Argentines but if I had an issue with them that big, I would just pay more for a secure nest.
