I am also having a major ant problem. I have read all of the great information on the site. I tried the cinnamon, bay leaves, cloves, cayenne and black pepper but these ants are troopers and they just filed over the mounds one by one. However the vinegar did stop them in their tracks, well at least for now.
The problem I am having is that I live in a craftsman house with a crawl space. I am temporarly able to stop the ants at one entrance but they just find another way in, then another, then another. I just can’t keep up with them, they are inside the walls and under the house which I have no access to.
Please help. I am off for vacation in 48 hours so any advice would be greatly appreciated.
