Flies can be extremely tenacious, irritating and dangerous foes. Flies thrive on filth and lay their eggs in garbage or compost which is then an abundant food source when the larvae emerge. Adult flies fly back and forth between food and filth and because flies cannot eat solid food, when an adult fly rests on your food it vomits on it to dissolve it and then sucks it up. This process spreads diseases that affect you and your family. The serious diseases flies foster include typhoid, diarrhea, cholera, anthrax, tuberculosis and conjunctivitis, etc. Luckily there are some simple home remedies to repel or eliminate these flies altogether. Here are some of the most effective for you to try today.
