WHY ARE THERE ANTS IN MY ROOM?

look out your window at all your neighbors homes...within 50 foot radius of the houses there will be thousands of ants, as many as a dozen different species...the same as your house. Unless you try to create some sort of barrier (usually chemical) you will have ants getting inside hunting either moisture, food or a place to nest....not sure how your maid is supposed to of tracked in the ants...
