iD request Oregon

I'm not sure this is the right subreddit, everyone here seems to like ants, but I'm trying to ID these guys so I can get rid of them. Oregon, they are roughly the size of a grain of rice. The loved, and I mean loved when I had tero out for them. After about a week of hundreds of them enjoying the tero they started to diminish in numbers. I cleaned up but I'm still seeing a few every now and then. So I'm sure there's plenty more somewhere. Now I'm using Maxforce Quantum 0.03% Imidacloprid Ant Control Liquid Bait and they just don't seem interested in it.
