Causes Of Fly Infestation: Understanding The Sudden Increase In Flies In Your Home

The sudden increase in flies within a home can be a perplexing and bothersome issue for homeowners. Understanding the causes behind this infestation is crucial in order to effectively combat the problem. Flies are attracted to decaying matter, as it provides both a food source and a suitable environment for them to reproduce. Even in a clean household, the presence of rotting substances, such as food scraps in garbage cans or disposals, can serve as breeding grounds for flies. Additionally, flies thrive in warm temperatures, with temperatures of 75 degrees Fahrenheit and higher being optimal for their eggs to survive and hatch. Bathrooms, laundry rooms, and areas surrounding appliances often offer the ideal conditions for fly proliferation. Furthermore, flies possess a relatively long lifespan of 15 to 30 days and reproduce rapidly, with a single fly capable of initiating an infestation. To effectively address this issue, it is important to maintain cleanliness in trash cans, reduce temperatures in potential fly breeding areas, and install screens on doors and windows. Seeking assistance from professional pest control services can also prove helpful in managing fly infestations.

Key Takeaways

  • Decaying matter is a common cause of fly infestation, as flies are attracted to and lay eggs in decaying matter.
  • Warmth and favorable temperatures contribute to fly growth, with temperatures of 75 degrees and higher being ideal for flies.
  • Flies have a long lifespan of 15 to 30 days and breed quickly, so a single fly can cause a fly infestation if not eliminated.
  • Proper sanitation and prevention measures, such as keeping trash cans clean and installing screens on doors and windows, can help combat fly infestations.

Causes of Fly Infestation

The sudden increase in flies in your home can be attributed to various causes, such as the presence of decaying matter, which serves as an attractive food source and breeding site for flies, as well as the warm temperatures that provide ideal conditions for fly growth and reproduction. Flies are scavengers that feed on dead and dying matter, and they lay their eggs in decaying organic material. Garbage cans and disposals are prime breeding sites for flies. Even a clean house can have hidden sources of rotting matter that attract flies.

Furthermore, flies require warmth for their eggs to survive and develop into adults. Temperatures of 75 degrees Fahrenheit and higher are ideal for fly growth, making bathrooms, laundry rooms, and areas around appliances common hotspots for infestations.

The effects of fly infestation on health can be significant, as flies can carry and transmit various pathogens that can cause diseases such as diarrhea, food poisoning, and eye infections.

To prevent fly infestations in homes, it is important to keep trash cans clean and take out the trash frequently. Reducing temperatures in areas where flies originate, such as by using air conditioning or fans, can also help deter their growth. Additionally, installing screens on doors and windows can prevent flies from entering the house. Proper sanitation practices and prompt elimination of flies are crucial for effective prevention and control.

Decaying Matter

Decaying matter serves as a common attractant for the presence of flies in indoor environments. Flies are scavengers that feed on dead and decaying matter, making it an ideal breeding ground for them. To prevent fly infestation, it is crucial to identify and eliminate common sources of decaying matter.

  1. Garbage cans and disposals: These are prime breeding sites for flies as they often contain rotting food waste. Regularly emptying and cleaning garbage cans, as well as ensuring that disposals are properly maintained, can help prevent fly infestation.
  2. Pet waste: Animal feces can attract flies and serve as a breeding ground. Promptly cleaning up after pets and disposing of waste in sealed bags can help reduce the presence of flies.
  3. Rotting organic materials: Even in a clean house, there may be hidden sources of decaying matter, such as spoiled fruits or vegetables, dead insects, or damp organic materials. Regularly inspecting and disposing of these items can help prevent fly infestation.

By identifying and addressing these common sources of decaying matter, individuals can effectively reduce the risk of fly infestation in their homes.


Warmth plays a significant role in creating favorable conditions for fly eggs to hatch and for successful fly growth. Flies require temperatures of 75 degrees Fahrenheit and higher for their eggs to survive and develop into adult flies. This makes areas such as bathrooms, laundry rooms, and spaces around appliances ideal for fly breeding due to the warmth they provide. Additionally, the effects of climate change can contribute to an increase in fly infestations. Warmer temperatures and changing weather patterns can create more favorable conditions for flies to thrive and reproduce. Furthermore, indoor heating systems, especially during the colder months, can inadvertently promote fly breeding by creating warm environments within the house. It is crucial to address these factors and implement proper sanitation and prevention measures to combat fly infestations effectively.

Long Lifespan and Fast Breeding

Longevity and rapid reproduction are key factors contributing to the proliferation of flies in residential environments. Flies have a lifespan of 15 to 30 days and are capable of breeding quickly. A single fly can cause a fly infestation as they lay multiple eggs, which hatch into adult flies and continue the breeding cycle. It is important to address fly infestations promptly as they can pose various health and hygiene risks. Flies are known to be carriers of disease-causing pathogens, including bacteria and viruses, which can contaminate food and surfaces in the home. To prevent fly infestations, proper sanitation and prevention measures should be implemented. This includes keeping trash cans clean, taking out trash frequently, reducing temperatures in areas where flies originate, and installing screens on doors and windows to prevent their entry into the house. By implementing these strategies, homeowners can effectively combat and prevent fly infestations, ensuring a healthier and more hygienic living environment.

Tips to Combat Flies

To effectively combat and prevent fly infestations, it is essential to implement proper sanitation and prevention measures. Here are four key strategies that can help in the battle against flies:

  1. Natural fly repellents: Using natural repellents can deter flies from entering your home. Essential oils such as lavender, eucalyptus, and citronella are known to repel flies. Simply mix a few drops of these oils with water and spray around windows, doors, and other entry points.
  2. DIY fly traps: Creating homemade fly traps can be an effective way to catch and eliminate flies. One popular method is to make a trap using a plastic bottle filled with a mixture of sugar water and vinegar. Flies are attracted to the scent and will enter the bottle, becoming trapped.
  3. Clean and remove potential breeding sites: Flies are attracted to decaying matter, so it's crucial to keep your house clean and free of any rotting food or waste. Regularly empty and clean garbage cans, dispose of food scraps properly, and clean up spills promptly.
  4. Install screens on doors and windows: Installing screens on doors and windows can act as a physical barrier, preventing flies from entering your home. Make sure the screens are in good condition, with no holes or tears that flies can squeeze through.

By implementing these natural fly repellents and DIY fly traps, along with maintaining cleanliness and using physical barriers, you can effectively combat and prevent fly infestations in your home.

Types of Flies

The different types of flies commonly encountered include the housefly, horse-fly, blow flies, common fruit fly, and cluster fly. Each of these fly species has unique characteristics and behaviors. Houseflies (Musca domestica) are the most common and are attracted to decaying organic matter. Horse-flies (Tabanidae) are known for their painful bites and are often found near bodies of water. Blow flies (Calliphoridae) are attracted to rotting meat and carcasses. Common fruit flies (Drosophila melanogaster) are small and are often found around ripe or decaying fruits and vegetables.
