Put some flour down where the ants go. They will bring it back and then they will die.

Also if any trees or things are touching the house you should cut them down.
Put some mothballs around the corners of your kitchen. And you could spray bugspray on the corners as well for more protection :)
Ant baits. Most drugstores sell them. Also try Home Depot. I had enormous black carpenter ants in my kitchen and first floor bathrooms. The ant baits worked. They are sometimes also called ant traps.
Use ceyenne pepper.....ants will not cross over.
Buy ant killer granuals and spread them on the outside of your house next to the foundation. Depending on where you live you might have to repeat. It keeps them out for several months.
u have to get special stuff to get rid of those. I had them at work for a while untill our new exterminator put some type of gel out especially for them and now they're gone
Put some flour down on their way, window panes etc.
Place a piece of melon (cantelope/watermelon) in your yard a little ways from the house. The ants will go for the melon instead of the house!!
