Flies are one of the most annoying pests in the world. One well-known fly, the house fly, is connected with over 100 disease-causing pathogens. These pathogens can cause disease in humans, including: typhoid fever, cholera, dysentery, hepatitis, polio, tuberculosis, anthrax, and many types of parasitic worms.

For every fly seen, it is estimated that there are 19 more hidden from view. That means humans don’t even see 95% of flies present at an infestation. The U.S. Department of Agriculture estimates that flies contaminate or destroy $10 billion of agricultural products each year.
