I live in Tacoma WA. It has been so cold this spring, If you have been seeing ants inside, they are coming from inside your home. The median temperature outside needs to be 50F for them to be active outdoors.
Since they don't eat wood, but rather insects, it is common to see them inside in the early spring, then have them disappear as the weather gets better and they are able to forage outside.
You probably have a brood nest. That is a satellite nest where the larvae and reproductive (winged) ants are kept.
In the Puget Sound that nest is usually on the South side of the house where it is dry and warm. Finding moisture is not a problem for our ants, The main nest is normally outside deep in a tree or log.
Carpenter ants come in different sizes. The best thing to do is take some prisoners, so they can be properly identified. Dead is OK but they should not be smashed.
And John is right, don't panic. The weather will need to be a little warmer before any treatment will be effective anyway. Carpenter ants can do serious damage, but often do little or no damage. They are not as serious as termites, which actually consume wood.
In the past we would drill and treat the voids in your home.
Now a treatment with a non repellent product like Termidor can be done without drilling any holes.
