OMG............yes I went into the kitchen at night I didn't know they were nocturnal and the counter and wall were covered with them. I never had big black ants before. I was like a crazy person killing them. I realized they were coming in from the deck door. I wiped everything down with peppermint oil and set up little cup with borax and sugar/honey. I also sprayed outside by the door. Within a day they were gone. However 2 weeks later they decided to send there cousins to visit. The same thing happened walk in the kitchen at night they were all over the counter and wall. They were the smallest ants I have even seen. I did the same this with the peppermint oil. So far so good.
