Frequently Asked Questions about Black Fly Dangers. Q: Can Black Flies carry diseases? A: Yes, they have been known to transmit diseases to humans and animals. In Africa, Central America and South America, Black Flies can transmit two diseases to humans: onchocerciasis, known as âriver blindness,â and mansonellosis.
Insects that carry diseases are called vectors and are more common in less developed countries. Controlling insect population around humans and animals helps to reduce the transmission of disease. Use building materials that are pest-proof, eliminate pest food sources and use physical traps or poison.nsects that carry diseases are called vectors and are more common in less developed countries.
