Because people correctly associate flies with filth, these pests disgust and annoy residents in homes. The insects can also transfer disease organisms when they touch food and kitchen surfaces. In addition, certain fly species can inflict painful bites on humans and animals.
Disease
Millions of microorganisms may flourish in a single fly’s gut, while a half-billion more swarm over its body and legs. Flies spread diseases readily because they move quickly from rotting, disease-laden garbage to exposed human foods and utensils. Every time a fly lands, it sloughs off thousands of microbes which can cause serious illnesses like:
Bloodstream infections
Diarrhea
Food poisoning
Meningitis
More than 100 pathogens are associated with the house fly, including Salmonella, Staphylococcus, E. coli, and Shigella. These pathogens can cause disease in humans and animals. Some of the diseases include:
Cholera
Bacillary dysentery
Hepatitis
Typhoid fever
