You're probably tired of hearing about ant salvation, but I just got linked to you and the suffering. Have you happened to try Sevin Dust? It sounds like you have an infestation of crazy ants, which are a co-operative colony ant that don't build nests, love to cluster around electric sources, and get absolutely everywhere. Where I'm at, they beat hornets and -fire ants- by sheer numbers.
We tried literally everything that you can buy yourselves over the counter and nadda. The only thing that works is getting the house/surrounding areas bombed regularly by professionals with stuff that makes it very hard for me to breathe, but then we are ant free inside the house for a couple of months.
It’s expensive as all hell but it’s worth it not to have ants crawling out of my keyboard cause haha, my sanity cannot deal with that anymore. Nope nope nope.
