Blow Fly Identification Guide

What Are Blow Flies?

Blow flies are a type of filth fly. Females lay their eggs on carrion, excrement, and other decaying matter. After the eggs hatch the larvae use the carrion as a food source. These flies look similar to house flies, but grow larger in size (1/8th and 5/8th of an inch in length) and have a very metallic appearance. Their coloration varies- blue, green, gold, or black.The blow fly’s worm-like larvae are pale yellow to white in color, are eyeless, and are legless. Their back end is larger and rounder than their tapered head and they have hook-like mouthparts.

Are Blow Flies Dangerous?

Blow flies are dangerous flies to have live in or near your home. These flies are constantly landing on excrement, decaying organic matter, decaying pieces of meat, and dead animals. There is a high number of bacteria and parasites that live on their bodies and legs. As they fly and move around your home they contaminate food and surfaces, spreading things that cause diarrhea, cholera, tularemia, and other serious diseases.
 

Why Do I Have A Blow Fly Problem?

Blow flies have the potential to be a problem at any time of the year. They choose yards and homes that offer them a place to lay their eggs and feed. These flies also move inside while foraging for food through spaces around windows and doors, and cracks in exterior walls or foundations.

Where Will I Find Blow Flies?

Blow flies live outside together in groups gathering around their feeding and breeding sites. Gardens with decaying vegetables and fruits, yards with animal feces, trash cans, and compost piles are all places blow flies gather. Inside of homes, they breed behind walls, in crawl spaces or under floors. The females lay their eggs in dead rodents or other animals that have found their way into your home and died.
