Ants

I've been getting ants in my bathroom for the last week or so. I've cleaned it thoroughly a few times since they made their first appearance but they've returned each time. I think I finally nailed down what it is they are attracted to, the residue of my mouthwash. I discovered this when I found a bunch of ants in my mouthwash and going to and from the bottle. YUCK!!!!!!!! Sadly, I felt compelled to dispose of my mouthwash, now I need to get some more, but I think I'll have to go for the non-mint kind. If that still attracts them I'll be a very sad person...one with lower quality breath.
