Flies are of the insect order Diptera, which means “two-winged.” Diptera includes flies, mosquitoes, gnats and midges. There are an estimated 120,000 species of flies that have been described by science, although the actual number of species in the world is much larger. Adult flies live in a wide range of habitats and display enormous variation in appearance and lifestyle. Males and females are hard to distinguish, females are usually larger and sometimes males have enlarged eyes which meet on the top of the head.
Flies are not just a nuisance; they carry diseases such as tuberculosis, typhoid, dysentery, diarrhea and other foodborne illnesses which can pose a serious health hazard to people and animals. The mechanics of how flies spread disease is dirty; they frequent areas where they can find rotting garbage and human or animal waste, then carry germs from those areas to the food we eat. Ensuring that your home or business is clean is the first and most important step in fly control.
Very important in nature in the decay process of carcasses, blow flies are often the first insects to arrive after an animal dies.
Blow flies and bottle flies are medium sized, robust flies approximately 1/5 of an inch in length and are easily identified by their metallic appearance. Coloration varies mostly from blue, green and gold to shiny black.
Biology and Behavior:
- Blow/bottle flies will lay their eggs on animal carcasses and manure as well as decaying vegetables, grass clippings and leaves.
- Their eggs are laid on a suitable decaying organic material and the larvae hatch out and burrow beneath the surface where they feed.
- After a few days feeding, larvae emerge and crawl a short distance away from the breeding source and burrow into the soil to pupate. Adults emerge several days later.
- The entire blow/bottle fly life cycle can take from 10 days to three weeks depending on the environmental conditions.
- Forensic entomologists track these environmental conditions and compare larval development from maggot specimens collected from bodies to help determine time of death.
- A single mouse carcass can produce over 100 adult flies.
Fly Prevention Tips:
- The presence of blow/bottle fly adults and larvae inside of structures is usually related to the presence of a carcass, such as a rodent or bird that died inside a wall void, attic or crawlspace.
- Pet feces, piles of moist grass clippings and leaves and poorly maintained garbage cans are all good sources of blow/bottle flies in a residential setting.
- Removing the breeding source is the best long term control. However, some carcasses are difficult or unfeasible to locate. In such cases, relief may be attained by vacuum removal and crack and crevice dust applications to reduce numbers of emerging larvae.
- Baits, insect light traps and residual applications to resting sites help eliminate adult populations.
