I had an ant problem. Briefly.
Ants seemed to like one of my windows. Just one. There is a bush near that window, and likely that had something to do with it.
I am an organic-solutions sort of person so I decided to try that first. So… I cut back the bush so it doesn’t touch the house. I washed the sill and stool cap of the window to get rid of any scent markings left by ants. Then, I sprinkled cayenne pepper on the sill and the bottom of the sash. No more ants!
Just thought I would pass that along in case anyone else wants to get rid of ants without resorting to poisons. I have no idea if it will be consistently effective or if it works with all types of ants. But it could be worth a shot.
Have a great day!
