Ugh, I have seen 2 this week and I don't know what they could be. I don't even know what to look up to see what they are. About the size of an ant. They both were so fast, I can't even be sure they were the same type, but I think they were too quick to be ants. One I smashed and one just got away. Any ideas what very fast small insects could be? We could be bringing them from outside in the evening. I hate bugs!
