The bacterium Bacillus thuringiensis proved to be a good candidate in controlling Musca
domestica, associated with poultry houses, as a carrier of a wide range of pathogens infecting man
and animals. Chicken feces are good media attracting flies for breeding. The bacterium was used in
commercial form and a laboratory preparation form to contaminate feces or administered orally to
chicken. Reduction in the percentages of pupal and adult emergence was recorded for six days after
chicken feeding by two doses of B. thuringiensis (1.00 and 5.00 mg/ kg).
