Large and small webbing clothes moth larvae, Tineola bisselliella (Hum.), are attracted to wool stained with human urine, human sweat, tomato juice, milk, beer, black coffee, and beef gravy. Small larvae of the furniture carpet beetle, Anthrenus flavipes Lec., also feed on such stains. Small larvae of the black carpet beetle, Attagenus piceus (Oliv.), are less attracted. Large larve of the black carpet beetle show no preference for the stained areas. The large larvae of the furniture carpet beetle are attracted to beer and tomato juice stains, and show an occasional preference for other stains. Wool stained with butter, tea, cola soft drink, and a 5per thousand sugar solution does not attract any of the larvae. Tests under starvation conditions showed that the larvae of the furniture carpet beelte fed on stained nylon and Dacron. The larvae of the black carpet beetle fed on nylon stained with human sweat. Stained Orlon and Dynel were not fed upon by any of the larvae of the three species.
