No summer picnic would be complete without hamburgers, hot dogs and …. blow flies. They are regular (unwanted) guests at warm weather cookouts, especially when meat is on the menu.
Blow flies are a diverse group of flies ranging in size from 1/4 – 1/2 inch in length, and generally have a metallic sheen to their bodies. They may be black, blue, coppery green, olive green, or bronze in color. All adult blow flies have blunt mouthparts and do not bite.
Blow fly larva, called maggots, feed on dead and decaying organic matter and help to break it down. In addition to meats and flesh, they often infest wounds of sheep, deer, cattle, and other animals. But, they can also be attracted to nectar, carrion, garbage, and other refuse. Blow flies deposit eggs in wounds or on dead carcasses. The fly larvae which soon hatch feed on decaying flesh or matted hair. As a rule, blow fly larvae never attack healthy tissues.
As disgusting as all of this may sound, blow flies actually serve several useful purposes. In nature, they help to facilitate decomposition, and are often the first to arrive at a crime scene. If you’ve watched a primetime police drama in the last 10 years, you probably already know that blow flies have been successfully used by law enforcement to solve crimes. By using the fly’s development along with climatologic data, police can determine the timeline of a crime. Blow fly maggots have also been used successfully in medicine to clean out necrotic tissues of patients.
However useful, most people do not want to see blow flies in their homes! If you see blow flies in your home, it usually means that there is an animal carcass nearby. Most likely, a mouse, rat, squirrel, bird or some other type of urban wildlife has died within your structure. Perhaps, underneath your home in a crawl space, behind a wall void or in an attic space, blow flies are traveling to the carcass to break it down.
