Flies, Pests & Insects

98 percent or more of the flies caught in houses are house flies. Because they can transmit typhoid fever, cholera, dysentery, pinworm, hookworms, and some tapeworms, house flies are regarded as a grater threat to human health than most other insects. Pathogenic organisms are picked up by flies from garbage, sewage and other sources of filth, and then transferred on their mouthparts and other body parts, through their vomitus or through their feces to human and animal food.
