Ants can be very difficult to get rid of depending on species because their colonies are underground. Generally speaking, most ants you see around the home can be eliminated by putting out a small amount of a sticky, sweet liquid called "Fatsco" on a small piece of paper around your home.They carry this back to the colony and it kills off the other ants in the colony. There are natural remedies as well if you have pets that I highly recommend you do instead of poisons!
Some species of ants such as pissants, fire ants etc. are much more difficult to eradicate without a professional because their colonies are much larger and go for long distances underground making it next to impossible to kill all of them, so they just keep up the life cycle and keep coming back!!, also they are harmful and dangerous to humans and pets as well!
I would suggest you contact a professional to tell them the type of ants you see and ask them what the best thing to do is to get rid of them for good.
