Ok, so here are some pictures of the ants that are invading my home and I have no idea or the slightest clue what kind of ants they are. These were the best pictures I could get. I know three things for sure:

1.) They don't sting
2.) They have different sizes
3.) They have two nodes(the thing before the abdomen)







At first I thought it was the crazy ant, but it's supposed to have a spine thing and I don't see one, so any help is greatly appreciated. Just for informational purposes I'm from Louisiana.
