I had this Issue for a little while, there was a huge ant colony living under our and neighbors yards, and they were able to get into my room through the garage. 

They found some old Soda cans I had forgotten in my room and eating/collecting the small amount of syrup remaining in them. I cleaned my room and set up some traps, but they for a while kept following the chemical trail that was telling them "Food this way" even though there wasn't anymore. As long as that chemical trail exists they  will follow it not knowing whats at the other end. Its why you get Ant mills where they walk in circles to their death.

Eventually we had a leak in city pipe that connects the Water Main under the road to junction that had our and our neighbors external Shutoff valves. That leak was small, but gradually oversaturated the soil to the point water was running up out of the ground and down the sidewalk/road. Ever since then no more Ants, likely due to their colony being flooded.

That all being said I only ever got 1 Ant in my monitor, and it ended up dying at the bottom of the screen in the center above the brand logo, Its annoying but generally out of the way.

Damn the only thing that fixed your ant problem was a water main problem... that's shit luck.
