Flies why

Ensuring tightly sealed windows and keeping doors closed when not in use is valuable to help prevent fly entry inside the home. This is very important if prevention of overwintering flies such as cluster flies is needed. Residents may need pest professionals to figure out what attracts flies in your home and how to get rid of them. Contact the team at Orkin for removal. Call Residential Commercial. Fly Eating.

Flies are one of the largest groups of insects. Unlike most other winged insects, which have four wings, flies have only two. This difference distinguishes them from nearly all other insect orders. All flies go through complete metamorphosis—egg, larva, pupa and adult. These stages of development allow flies to take advantage of different breeding and living sites.

Fly eggs and larvae, for example, are not highly mobile and are generally found in moist or watery environments. Adults, on the other hand, are highly mobile—they can fly and locate food in wet or dry environments.

Because they can fly, adult flies can find even temporary food sources quickly, before they disappear. Immature flies larvae are legless and may live in drains, standing water, rotting foods, potting soil, or garbage. Smaller house-infesting flies include drain flies, fruit flies, phorid flies, and fungus gnats.

Larger flies, such as blow flies and flesh flies, occasionally invade homes to lay eggs on a decaying carcass. These flies rarely infest homes for long. House flies and mosquitoes rarely breed inside structures; however, they readily take advantage of open doors or unscreened windows to get indoors for food or shelter. Insecticides alone are rarely successful in eliminating indoor fly infestations.

Fly control is most effective when breeding sites in the structure are identified and eliminated. Because each type of indoor fly prefers slightly different breeding sites, identifying the fly should be the first step in any control effort. The following are descriptions of the most common indoor flies along with explanations of how to locate and eliminate their breeding sites.

All of the following flies are capable of breeding and living entirely indoors. These flies, however, are also found outdoors and may enter through open windows or doors.

Fruit flies Family Drosophilidae are common indoors and out. Infestations are most frequent during the summer when fruit flies are active outdoors— though indoor infestations are possible any time of year. They usually have reddish eyes. They are small enough to pass through window screens and can easily enter through open doors or windows. They can be distinguished from other small indoor flies by the feathery bristle arista on the tip of their third antennal segment.

Drosophila fruit flies are used widely in genetics research because of their ability to reproduce quickly. Under optimum conditions, the life cycle of a fruit fly can complete in as few as 8 days. Fruit flies are sometimes referred to as vinegar or pomace flies because they are attracted to vinegar and almost any decaying fruit. There are more than species of fruit flies in the U. Their food preferences can vary, but these flies will breed in almost any fermenting fruit or vegetable.

They are also commonly found in spilled syrups, wine, or beer—especially in moist places, such as under commercial kitchen equipment, bars, soft drink dispensers, and in cracked tile or flooring. In homes, breeding is more common in overripe or damaged fruits especially bananas and spoiling vegetables such as rotting onions or potatoes. The larvae feed on yeasts associated with the decay of these materials. Fruit flies with black eyes, known as dark-eyed fruit flies, breed more frequently in drains, around bathrooms and urinals, and even in rotting cacti.

Fruit flies do not bite, but most people consider them annoying. In hospitals, they are considered a public health risk because of their potential for contaminating sterile surfaces. In addition to bacterial contamination, ingestion of fruit fly-infested food has been reported to cause intestinal upset, diarrhea, or intestinal myiasis.

Health departments consider fruit flies in restaurants or other food service businesses to be unsanitary. Fruit flies can be controlled by taking out the trash or removing unrefrigerated, overripe fruit, or rotting vegetables. Locating and eliminating other breeding sites can sometimes be more challenging. Using traps or sprays may provide temporary relief from fruit flies, but eliminating the breeding site is essential for complete control. Phorid flies Family Phoridae are another fly found in homes and, even more commonly, in commercial buildings.

They are tan to dark-brown or black. Phorid flies have dark veins along the front edge of their wings. The veins in the central part of the wings are almost parallel and lack the linking cross veins seen in most other fly wings. Phorid flies have enlarged femurs on the third pair of legs, which make them good runners. Eggs are laid on or beside moist decaying materials.

Phorid fly larvae feed on a variety of decaying plant and animal matter. They are found in any type of moist, decaying material including: decomposing animal carcasses, garbage, drain pipes, flowers in vases, wet potted plant soil, garbage cans, broken garbage disposals, dung, feces, and fungi. Because phorid flies come from such unsanitary breeding sites, their presence around kitchens and in sterile areas is highly undesirable. Having a few phorid flies indoors is not unusual, but large numbers of them usually indicate unsanitary conditions.

Phorid flies have an amazing ability to penetrate soil to locate breeding sites. Another underground source of phorid flies is soil that has been contaminated by leaks around sewer lines. When such leaks occur under buildings, they can lead to severe indoor fly infestations and sometimes require expensive excavation to remove the contaminated soil. These highly mobile, hungry, sex-obsessed young adults are the ones that interact with us over summer.

Check out this blog post for more info on why summer is the hot month for insects. Both biodiversity and food security depend on pollination of native plants and crops. Most of the ingredients in that summer BBQ you were about to tuck into were probably grown thanks to insects. When you think of pollinating insects you probably think of bees or maybe even butterflies.

But flies are actually the unsung heroes of pollination, pollinating plants at least as well as any honeybee might. Honeybees actually pack the pollen away in special baskets on their legs which mean the pollen grains are not available for pollinating the next flower. Flies also help to pollinate hops in beer, apples in cider and grapes in wine. Could this be the livestock feedstock of the future?

While you might find flies maddening, lots of animals you love rely on flies for their food. Birds, lizards and frogs all enjoy chowing down on tasty flies as does my dog. So we know insects already play an essential role in the web of life, but new research shows they could be doing even more. While you might not want them spewing on your snag, they could be the food that fed the pig to make the snag.

We might not be quite ready yet in Australia to be eating insects ourselves, but we could instead feed insects to our farmed animals to feed to our growing population instead. Researchers have demonstrated that black soldier fly feed could partially or completely replace conventional agricultural feed.

Studies have shown that this feed is suitable for the diet of chickens, pigs, alligators and farmed seafood such as blue tilapia, Atlantic salmon and prawns with no adverse effects on the health of these animals.
