Fly bites can be painful and uncomfortable, and there are many reasons to avoid them. One of the most common reasons is that they can be a source of illness, and they can cause cholera, which can cause dehydration, vomiting, and muscle cramps. In severe cases, cholera can lead to low blood sugar and altered states of consciousness. Some cases of cholera even cause seizures and coma. Flies can also carry parasite eggs and bacteria.
Scientists believe that climate change is causing a decline in many types of flies. The global warming effect is likely to impact a variety of flies, including houseflies and dragonflies. One species that will be especially affected by global warming is the bone skipper fly, which feeds on carcasses picked over during the winter months. The species was thought extinct until researchers recently rediscovered it.
Houseflies are also a significant health risk, as their presence in our homes can affect our food. Their odor can tarnish it, and they carry harmful bacteria that can lead to serious diseases. Their feces are also dangerous, and their droppings can contaminate food.
While some types of flies can be harmful, others are beneficial. Many species of flies are helpful in the environment. Some clean up human waste, such as sewer gnats. These bugs can be dangerous to our health if their populations grow too large. Aside from cleaning up the environment, flies also clean up human waste. There are more than 1,000 species of flies, and many of them are beneficial.
