I don't know what kind of ants you have in your photos. They are hard to see. Even if they are carpenter ants, they do not eat wood like termites but they do chew to make tunnels. There are many types of ants and male ants are winged. Ants are very common and are difficult to eliminate. If they are not in the house or are not in an area that you or children use then they really don't have to be controlled. Here is a link to info about ants that should be helpful for you. http://www.extension.umn.edu/garden/insects/find/what-to-do-about-household-ants/
