The common house fly (Musca domestica) occurs worldwide. Adult flies are about 1/4 inch long, and gray colored overall with four black stripes on the thorax. House flies prefer to breed in animal waste, garbage, compost piles, etc., and can produce a new generation in 4 to 7 days under the best conditions. The habits of the adult flies potentially put them in contact with disease causing organisms and indeed they’re proven contaminaters of food.
