Analysis of field data collected over several years in three poultry housing systems (narrow caged-layer houses, high-rise caged-layer houses, and broiler-breeder layer houses) indicated that the baited jug-trap was a reliable method of sampling house flies, Musca domestica L.; sticky ribbons provided additional information on two other fly species. Relative frequency of house fly capture indic...
