I was called in for carpenter ants in this scenario. There was chewing noises going on in the ceiling.
When we arrived we noticed a Yellow Jacket activity on the front of the house but the customer insisted it was carpenter ants. We looked for trailing Carpenter Ants on the exterior of the structure but found none.
We had a Thermal Camera with us so we put it to use. Here is what we found

It was a Yellow Jacket nest over the bed and in the center of the room. You can see the path they used from the exterior of the structure to the nest. There is another room above this one.
These are some other images of the same room different angle an different colour palette.
