Do Flies Cause Harm to Humans?
Flies are beneficial to the environment. They help the decomposition of organic matter. This means that the food is less likely to become a food source for animals higher in the food chain. They also help transport pathogens from decaying organic matter. Despite their reputation as pests, flies are incredibly important to the natural ecosystem and human society. Their ability to survive in the environment and their complex evolutionary history is why they are so important.
While flies may not be harmful to humans, they are important disease vectors. Some species, including house flies, can transmit diseases, such as typhoid and cholera. In addition, they are known to carry parasites that can infect humans. To make matters worse, some species of flies can also transmit deadly diseases.
One study found that houseflies carry several pathogens. Some are resistant to antibiotics, including those from human and animal farms. These microbes can be passed on to people via the food and water they eat. However, experts agree that the risk of flies transmitting these harmful organisms is small.
If you are concerned about flies, you should take the precautions necessary to protect your property. Many flies are resistant to pesticides. Most of them are capable of dispersing to a large area.
