The constant presence of these pesky insects can be not only annoying but also a source of concern. In this article, we will explore the reasons behind the prevalence of flies in your backyard and provide some helpful tips to manage their population effectively. So, if you’re tired of constantly swatting away these buzzing nuisances, keep reading to discover the secrets behind their seemingly overabundance in your outdoor space.
Factors that attract flies
Presence of garbage or decaying organic matter
One of the main factors that attract flies to your backyard is the presence of garbage or decaying organic matter. Flies are attracted to the smell of rotting food, so if you have open trash bags or bins in your backyard, it’s likely to become a breeding ground for flies. To prevent this, it’s important to properly dispose of your garbage and ensure that it is tightly sealed to prevent flies from accessing it.
Standing water
Flies are also drawn to standing water, as it provides a breeding ground for them. If you have any stagnant water sources in your backyard, such as bird baths, puddles, or even unused containers filled with water, it’s important to eliminate them or use measures to prevent flies from accessing them. Regularly emptying and cleaning bird baths, fixing leaky outdoor faucets, and ensuring that water doesn’t accumulate in any containers can help reduce the presence of flies.
Overripe fruit or vegetables
Another factor that attracts flies to your backyard is the presence of overripe fruit or vegetables. Flies are attracted to the sweet scent emitted by these decaying fruits and vegetables. If you have a garden or fruit trees in your backyard, make sure to regularly harvest ripe produce and dispose of any overripe ones before they become a magnet for flies. Properly storing and covering fruits and vegetables can also help prevent flies from being attracted to them.
Animal feces
Flies are notorious for being attracted to animal feces due to the abundance of organic matter they contain. If you have pets or live in an area with wildlife, it’s essential to regularly clean up after them to prevent flies from being drawn to your backyard. Properly disposing of pet waste in sealed bags and cleaning up any animal feces in your yard will help reduce the presence of flies.
Open compost piles
While composting is an eco-friendly way to dispose of organic waste, open compost piles can easily attract flies. Flies are attracted to the decaying matter in compost piles, so it’s important to properly manage and cover your compost to prevent them from infesting your backyard. Regularly turning the compost to ensure proper aeration and covering it with a layer of leaves or straw can help deter flies from being attracted to it.
Uncovered outdoor trash bins
If you have uncovered outdoor trash bins in your backyard, flies will be inevitably attracted to them. The smell of rotting food and garbage is irresistible to flies, making uncovered trash bins a haven for them. To prevent this, make sure to use tightly sealed trash bins with lids that cannot be easily accessed by flies. Additionally, regularly emptying and cleaning the bins will help discourage flies from breeding and congregating in your backyard.
Flies as pollinators
Flies’ role in pollination
While bees and butterflies are often regarded as the primary pollinators, flies also play a significant role in pollination. Flies are attracted to flowers that have a distinct smell and often have a dull or dark color. As they visit these flowers to feed on nectar, they unintentionally transfer pollen from one flower to another, thereby aiding in the pollination process. This contributes to the reproduction and diversity of plant species.
Plants that attract flies for pollination
Certain plants have evolved to attract flies specifically for pollination. These plants usually have flowers that emit a foul or rotten odor, which is appealing to flies. Carrion flowers, for example, mimic the scent of decaying flesh to attract flies for pollination. Other plants with fly-pollinated flowers include skunk cabbage, corpse flower, and sneezeweed. By planting these types of flowers in your backyard, you can help attract flies and promote their role as pollinators.
Life cycle of flies
Egg stage
The life cycle of flies consists of four stages: egg, larval, pupal, and adult. The first stage is the egg stage, during which adult female flies deposit their eggs. Flies typically lay their eggs on decaying organic matter or in moist areas conducive to larval development. These eggs are often very small and difficult to see with the naked eye.
Larval stage
After the eggs hatch, the larval stage begins. The larvae, commonly known as maggots, emerge and feed on the organic matter present in their surroundings. They undergo several molts as they grow and develop. The larval stage is crucial for the growth and development of flies, as it is during this stage that they accumulate the necessary nutrients and energy to transition into the next stage.
Pupal stage
Once the larvae have fully developed, they enter the pupal stage. During this stage, the larvae transform into pupae and undergo significant changes internally. The pupae are enclosed in a protective casing called a puparium. Inside the puparium, the larvae undergo metamorphosis, gradually transforming into adult flies. This transformation process can take anywhere from a few days to several weeks, depending on the species of fly and environmental conditions.
Adult stage
The final stage in the life cycle of flies is the adult stage. Once the metamorphosis is complete, the adult flies emerge from the puparium. At this stage, flies are capable of flight and reproduction. They seek out suitable food sources, mate, and continue the life cycle by laying eggs. The lifespan of adult flies can vary depending on the species, but generally ranges from a few days to a few weeks.
Common fly species in backyards
House flies
House flies (Musca domestica) are one of the most common fly species found in backyards. They are attracted to decaying organic matter, garbage, and food leftovers. House flies can carry disease-causing bacteria and can contaminate food surfaces, posing a health risk to humans and animals.
Fruit flies
Fruit flies (Drosophila spp.) are tiny flies commonly found near ripe or decaying fruits and vegetables. They are attracted to the sweet smell emitted by fermenting fruits and can quickly infest kitchens and outdoor eating areas. Fruit flies can be a nuisance, but they do not pose significant health risks.
Blow flies
Blow flies (Calliphoridae family) are often attracted to animal carcasses, rotting meat, and decaying matter. They play an important role in decomposition by aiding in the breakdown of organic material. However, they can also be a nuisance and carry bacteria that can cause infections if they come into contact with food.
Cluster flies
Cluster flies (Pollenia spp.) are known for their habit of clustering in large numbers, especially in the fall and winter months. These flies are not attracted to decaying organic matter like other species; instead, they seek shelter in homes and other buildings to hibernate during colder months. While cluster flies do not pose any significant health risks, their presence in large numbers can be a nuisance.
Stable flies
Stable flies (Stomoxys calcitrans) resemble house flies but have a distinct feature – their piercing mouthparts. They are attracted to areas with livestock and can be a significant annoyance to animals and humans alike. Stable flies bite and feed on the blood of their hosts, causing discomfort and potential health issues.
Dangers and annoyance caused by flies
Health risks associated with flies
Flies are not only a nuisance but also pose health risks. They can transmit disease-causing bacteria and pathogens to humans and animals. When flies come into contact with sources of contamination, such as garbage, feces, or decaying organic matter, they pick up bacteria on their legs and bodies. These bacteria can be transferred to food, surfaces, or even directly onto open wounds, potentially causing illnesses such as diarrhea, food poisoning, or skin infections.
Food contamination
One of the main concerns associated with flies is their ability to contaminate food. As flies land on various sources of bacteria and pathogens, they can easily transfer these harmful microorganisms to exposed food or food preparation surfaces. This contamination can lead to the spread of foodborne illnesses and pose a significant risk to human health. It is essential to prevent flies from accessing food or food storage areas to reduce the risk of contamination.
Annoyance and disruption of outdoor activities
Apart from the health risks, flies can also be a major annoyance and disrupt outdoor activities. Whether you’re trying to relax in your backyard or enjoy a picnic at a park, the constant presence of flies buzzing around can be frustrating and intrusive.
