Marching Ants

This is a common sight in my home, I wouldn't mind so much if they also helped me pay the rent!
I accidentally discovered recently that the ants on my kitchen bench took a strong dislike to fresh garlic, so, noticing where their entrance hole was, I smeared fresh garlic around it, and to my utter astonishment it worked!
However, these are new ants on my dining table, and I've yet to follow the trail back to the source of entry, I will though, one day soon, and mark my words, oh vampires of the bug world, I will garlic your hole too!!
