Flies would have to rank as the number one most annoying
insect in the world. They not only get in your face but they
love to do nasty things to your food.
The most common fly is the House Fly and it can be found
nearly everywhere in the world. Flies, along with mosquitoes,
are the biggest disease spreaders in the Diptera group. Flies
differ from any other by having a single pair of wings.
