A count of 100 or more fecal or vomit spots per card per week indicates a high level of fly activity and a need for control. According to a study conducted in Texas, USA, breeding site suitability (in descending order), was horse manure, human excrement, cow manure, fermenting vegetable matter, and kitchen waste. However, another study found that structures containing swine, horse, sheep, cattle, and poultry varied in fly abundance, with swine facilities containing the most and poultry the least.
How to Get Rid of House Flies: Your Guide to Banishing These Pests Forever
Houseflies, while seemingly innocuous, are notorious carriers of a multitude of diseases due to their feeding and breeding habits. They’re often found in close proximity to waste, decaying matter, and food intended for human consumption. This combination puts them in a prime position to pick up harmful bacteria and pathogens, which they can then transmit to humans. Upon emerging as adults, houseflies face new dietary challenges due to their altered physiology.

At this temperature range, eggs hatch faster, often within a day or two. However, if temperatures drop below 10°C (50°F) or rise above 40°C (104°F), it can lead to increased mortality rates. In extreme cold or hot conditions, houseflies may not survive at all. Manure can also be treated with an insecticide, though this method is highly discouraged as it interferes with biological control of flies, often resulting in a rebound of the fly population.
Life Cycle of House Flies
These work by attracting the flies to light in the back of the trap and trapping them or using an electric zap to kill them. Some common insecticides for killing flies include pyrethroids, which are synthetic versions of natural insecticides found in chrysanthemum flowers, Johnson says. These chemicals inhibit flies’ nerves when they touch them, causing paralysis and death. Killing adult flies may reduce the infestation, but elimination of breeding areas is necessary for good management.

Body size ranges from about 5 to 7 mm (0.2 to 0.3 inch), and the conspicuous compound eyes have approximately 4,000 facets. Because it has sponging or lapping mouthparts, the housefly cannot bite; a near relative, the horse fly, however, does bite. The female deposits more than 100 slender whitish eggs (0.8 to 1 mm long) at a time, producing between about 600 and 1,000 eggs in her life. After several molts the dirty-whitish maggots (larvae), about 12 mm long, transform into pupae. The adults, when developed, expand a pouch (ptilinum) on the head and break off the end of the puparium to emerge. However, it’s also important to note that houseflies can have detrimental effects on their environment.
This preference for decomposing matter not only provides them with ample nutrition but also ensures their survival by hiding them from predators. The duration of the egg stage is heavily influenced by environmental conditions. In optimal circumstances—namely warm temperatures around 80°F (27°C)—the eggs hatch into larvae within a mere 8 to 20 hours post-deposition.
This means that the fly buzzing around your lunch could have been feasting on garbage or animal waste just moments ago. In terms of heredity, it’s worth noting that houseflies follow Mendelian principles – rules about how characteristics are transmitted from parent organisms to their children. The male housefly has XY sex chromosomes, while the female has XX sex chromosomes. Thus, the gender of a newborn fly is determined by whether it inherits an X or Y chromosome from its father.

Adults usually live 15 to 25 days, but may live up to two months. Longevity is enhanced by availability of suitable food, especially sugar. Access to animal manure does not lengthen adult life and they live longer at cooler temperatures. They require food before they will copulate, and copulation is completed in as few as two minutes or as long as 15 minutes.
Finally, examining their role in disease transmission reveals further disparities. Houseflies are known vectors for more than 100 pathogens, including salmonella and E.coli that can cause serious illnesses in humans. Fruit flies pose less of a health risk to humans but can be destructive pests to agriculture by damaging fruit crops. Blowflies aren’t typically direct disease vectors like houseflies but play an essential role in forensic entomology due to their attraction to dead bodies. These predators’ impacts extend beyond simply reducing housefly populations; they also help control the spread of diseases carried by flies. By consuming flies that have been in contact with harmful bacteria or parasites, these predators indirectly protect other creatures – including humans – from potential infections.
Maggots are known for their ability to consume a wide range of organic materials. They thrive on decaying matter such as rotting food, feces, and carrion. The nutrients within these substances provide the necessary energy for growth and development during this critical stage. Since house flies enter from outside, internal breeding sites are not common. However, interior garbage rooms and compactors provide a suitable environment for house fly breeding sites and should be checked. If the breeding site is not thoroughly cleaned or removed, these pests will continue to be a problem.
The selection of the egg-laying site is crucial for the survival of her offspring. Female houseflies are attracted to damp, decaying organic material such as compost heaps, garbage bins, or animal feces. Such places provide not only a safe haven for the eggs but also an abundant food source for the larvae once they hatch. A female housefly can lay up to 500 eggs in her lifetime, typically in batches of 75 to 150 at a time. These eggs are white and are usually laid on decaying organic matter, which serves as food for the larvae once they hatch. It’s only when they hatch into larvae or maggots that feeding begins.
The availability of suitable breeding sites profoundly affects the lifecycle of houseflies as well. They prefer moist organic material for laying eggs, such as rotting food waste or animal dung, where larvae can find ample nourishment after hatching. In the first section labeled ‘Egg’, picture tiny white oval shapes clustered together. Houseflies lay their eggs in decaying organic matter which provides food for the soon-to-be larvae. Each cluster typically contains 75 to 150 eggs which hatch within 24 hours due to the warm conditions provided by decomposing material. Adult houseflies are sexually mature within 36 hours after emerging from the pupa stage.
Unlike other insects, their second pair of wings has evolved into tiny structures known as halteres which act as gyroscopes, helping them maintain balance during flight. The intricate compound eyes, made up of thousands of individual lenses, offer a wide field of vision that aids in avoiding predators and finding food sources. The fascinating life cycle of a housefly begins with the egg stage. Each female housefly, having mated only once, can lay batches of about 75 to 150 eggs at a time.
Additionally, houseflies have been implicated in the transmission of parasitic worms such as roundworms and whipworms. These parasites live in the intestines of infected individuals, and their eggs are passed out through feces. Flies landing on these materials may ingest the eggs, which they later regurgitate or excrete onto human food sources leading to new infections.
The female housefly is an oviparous creature, meaning she lays eggs instead of giving birth to live offspring. She begins the egg-laying process soon after mating, typically within a day or two. The house fly, Musca domestica Linnaeus, is a well-known cosmopolitan pest of both farm and home. This species is always found in association with humans or the activities of humans. It is the most common species found on hog and poultry farms, horse stables and ranches.
Be sure to mount light traps away from entrances and windows, so they can’t be seen from the outside. Light traps are boxes with a light in the back that attracts flies. When the flies try to get to the light, they’ll either be killed with an electric zap or trapped, depending on what kind of light trap you choose.
