Never allow a speck of food to remain uncovered in dining room or pantry any length of time after meals. Never leave remnants of food exposed that you intend for cat or hens. Feed at once or cover their food up a distance from the house. Let nothing decay near the house. Keep your dining room and pantry windows open a few inches most of the time. Darken your room and pantry when not in use. If there should be any flies they will go to the window when the room is darkened, where they are easily caught, killed, or brushed out.
