P.W.
When I saw ants I wiped them away with vinegar.....in the kitchen, and then learned that was WRONG. That just messes up their trail and they spread out. I called a evironmentally friendly company. They came out and put down some stuff that attracted the ants. The ants took it back to the nest......gone forever!
Just google "non-toxic pest control" + Saint Charles, IL and see what you get, then price check.
