Are they found near an outside door, or near something that has been brought in from outside? Do you have any potted plants in the house (perhaps not in that particular room) or anything that has soil? It is rare to find cutworms inside the home, although it does sometimes occur. They are not a house pest. Perhaps a moth may have gotten inside and laid eggs in the soil of a potted plant? The larvae may then have hatched and are roaming to look for food. Or, some may come inside if the door is open (or they may hitch a ride on the door edge), seeking warmth to pupate.
