Walls should be swept down once a week, giving attention to corners, under and behind nests, perches, etc. For this purpose a splint broom, such as is used around stables, is most useful.
For thorough cleansing after all loose dirt has been swept away nothing is superior to whitewashing. It makes the room lighter, sweetens the air, and is a "cold shoulder" to all vermin. A sprinkling of dilute carbolic acid is a safeguard against disease. Perches are best cleaned by washing with some liquid insecticide, and then allowing them to dry in the sun. A good wash is made by dissolving half a cake of any laundry soap in ten quarts of water and adding five tablespoonfuls of kerosene oil.
