Blow flies do not bite, they make loud buzzing sounds. These flies carry hundreds of different species of bacteria, many of which are harmful to humans. The life cycle of blow flies is short, lasting about 3-4 weeks. Blow fly larvae are known as maggots, and look like tiny, pale-white worms. These pests invade home for food sources like rotting produce or decaying meat. If you are seeing blow fly activity indoors, chances are there is something rotting nearby.
