A rolled newspaper, a flyswatter or even the palm of your hand can all be weapons in your battle for fly control. These tiny creatures are often a harmless nuisance, but there may come a time to consider a pest control service. Sometimes fly season just doesn’t seem to end.
When people think about flies, the first thing to come to mind is often the common house fly; however, there are many more species. Flies are classified as part of the order Diptera, which is estimated to have a million species, but only 125,000 have been described. The following are species you may encounter:
The Anatomy of a Fly
Flies are characterized by having a single pair of wings used for flight, while the hindwings have evolved into sensory organs. These sensory organs facilitate their ability to maneuver. If you’ve ever wondered why fly control can be so difficult, this added maneuverability is part of the reason. Flies have mobile heads and compound eyes that allow them to see information from a variety of angles. Depending on the species, flies can have a mouthpiece designed to pierce and suck in nutrients or to lap and suck in nutrients. These insects also have an ability to cling to smooth surfaces and walk up walls due to the claws and pads on their feet.
Because of the diversity of fly species, some have developed hardy adaptations to their environment. Shore fly larvae and a few Chironomidae can live in hot springs, crude oil, sulfur springs, glaciers, saline springs and septic tanks. The larvae of the Megaselia scalaris can incorporate shoe polish and paint into their diet.
A Bug’s Life Cycle
The life cycle of a fly consists of four stages: egg, larva, pupa and adult. The common house fly provides a typical example. House flies lay eggs that resemble grains of white rice. These eggs are often laid in dark, damp places. Compost, garbage and feces are popular sites for fly eggs. Up to 150 eggs can be laid in a single batch, with five or six batches laid over a period of a few days.
The eggs hatch within a day and become larva, also known as maggots, that feed on their environment for three to five days. When the maggots are ready to pupate, they find a dark place to form a protective shell, similar to a butterfly’s cocoon. The pupae grow wings and legs and emerge after three to six days as fully-grown house flies.
It only takes another two to three days for female flies to be ready for reproduction, thus starting the cycle anew. Moreover, adult house flies can live for two to four weeks, depending on conditions. This rapid life cycle can make fly control a difficult process.
The Ecological Importance of Flies
While flies can be both a nuisance and a danger, they also play an important role in the ecological community as predator, prey and parasite. Many animals rely on flies as a source of food, while at the same time, flies consume various organic matter. Some of these insects play an important role in helping to decompose matter in either their adult or larva stage.
In addition to aiding decomposition, flies play an integral role in the pollination of flowers. It’s estimated that 71 families in the order Diptera regularly visit flowers, and over 550 species of flower are routinely visited by flies. Depending on the local ecology, flies may be the only insect that facilitates a plant’s pollination, or they may share the role with another insect such as bees. Some flies go to flowers to feed on the nectar while others prefer pollen. A few types visit flowers to lay eggs or to seek shelter from the weather. Some flowering plants exercise fly control by tricking the insects into visiting their flowers by emitting scents that mimic decaying flesh.
The Risks Posed by Flies
Flies can pose serious dangers to the health and wellbeing of humans and livestock. Because many flies land on and feed on decomposing flesh, feces and other bacteria-laden garbage, they can quickly spread bacteria and disease. A common method of fly feeding involves vomiting and defecating on almost everything they land on, which further aides in the spread of disease.
One way to prevent the spread of sickness is to dispose of food that flies have landed on. A fly infestation could potentially facilitate the transfer of any of the following diseases:
Other flies such as the mosquito prefer a more direct approach by biting their victims. Mosquitoes are responsible for the deaths of 1 million people each year due to the diseases these insects can spread. The lack of fly control is a serious concern in all parts of the world though areas with large amounts of standing water can be more severely affected.
In the United States, one of the most serious diseases carried by mosquitoes is the West Nile virus. Since 1999, the United States has reported 44,000 cases. About half of those reported cases resulted in an infection of the spinal cord and brain, and 1,900 people died. West Nile can cause body aches, headache, rash, fatigue, weakness, diarrhea and joint pain. If you suspect you may have contracted an illness by a mosquito or other fly, contact your physician.
Prevention and Eradication Strategies
With so many different species of fly to contend with, fly control can be a difficult challenge. There are a few steps you can take to minimize your risk of infestations:
If these steps aren’t enough to address your fly problems, it may be time to call a Baton Rouge pest control service to professionally address the issue. Your hand or newspaper may end the annoyance of an individual fly, but professional services have the experience and equipment to deal with more comprehensive fly control issues.

I really enjoy researching and writing about pests. The more we know about bugs, the easier it becomes to control them.
