That's what partners are for, help us out :) And you seem to have found a very nice one!
Same happened to me last year, I literally tried every trick in the book. And all of a sudden, they were gone.
I had a similar experience with ants in my house and I am pretty sure that they left on their own and will be back at some point! They may have a pattern or something triggers a change in their route, can't tell for sure. I wouldn't know what else to tell you except good luck!
Thanks 👍
