Frequently Asked Questions (FAQs) about Flies in Houses

1. What Attracts Flies to Houses?

Flies are attracted to houses primarily by the availability of food sources, warmth, and potential breeding sites. According to research from the University of California, Davis, in July 2023, P: Flies are drawn to organic matter, such as food spills, garbage, pet waste, and even decaying plant material. Flies possess a keen sense of smell, allowing them to detect these attractants from a considerable distance.

1.1. Food Sources

Flies are opportunistic feeders and are attracted to a wide variety of food sources. Flies consume almost anything edible, from sugary substances to decaying organic matter.

Uncovered Food: Leaving food scraps on counters or tables is an open invitation for flies.
Garbage: Overflowing or uncovered garbage cans are a major attractant.
Pet Food: Pet food left out in bowls can also attract flies.
Spills: Even small spills of sugary drinks or sauces can be enough to draw them in.

1.2. Warmth and Shelter

Houses offer a stable and warm environment, which is particularly attractive to flies during colder months. The structure of a house provides protection from the elements, making it an ideal refuge.

Stable Temperatures: Consistent indoor temperatures are more appealing than fluctuating outdoor conditions.
Protection from Weather: Houses provide shelter from rain, wind, and extreme temperatures.
Breeding Sites: Certain areas within a home, like damp basements or leaky pipes, can serve as breeding grounds.

1.3. Breeding Sites

Flies need suitable places to lay their eggs and for their larvae to develop. Houses can inadvertently provide these breeding sites.

Drains: Kitchen and bathroom drains can accumulate organic matter, providing a food source for larvae.
Garbage Disposals: Food particles trapped in garbage disposals can also attract flies.
Moist Areas: Damp areas under sinks or in basements can be breeding havens.

2. What Kind of Flies Are Commonly Found in Homes?

Several types of flies commonly invade homes, each with its own preferences and habits. Identifying the specific type of fly can help in targeting control measures.

2.1. House Flies (Musca domestica)

House flies are one of the most common types of flies found in homes. They are medium-sized, typically gray, with four dark stripes on their thorax.

Appearance: Small, brown or tan.
Habits: They are attracted to fermenting fruits, spilled juices, and other sugary substances.
Breeding: Fruit flies can reproduce quickly, making infestations challenging to control.

2.3. Drain Flies (Psychodidae)

Drain flies, also known as moth flies or sewer flies, are small, fuzzy flies that are often found near drains and sewers.

Appearance: Small, fuzzy, with rounded wings.
Habits: They breed in standing water and organic sludge in drains, sewers, and septic tanks.
Identification: Their presence often indicates a plumbing or drainage issue.

2.4. Blow Flies (Calliphoridae)

Blow flies are larger than house flies and are often metallic blue or green in color.

Appearance: Large, metallic blue or green.
Habits: They are attracted to decaying meat, carcasses, and garbage.
Significance: Their presence often indicates a dead animal nearby, either inside or outside the house.

2.5. Phorid Flies (Phoridae)

Phorid flies, also known as humpbacked flies, are small, dark flies that have a distinctive humpbacked appearance.

Appearance: Small, dark, with a humpbacked shape.
Habits: They are attracted to decaying organic matter, including sewage, garbage, and carrion.
Location: They can breed in unusual places, such as under leaky pipes or in damp crawl spaces.

3. Are Flies in the House a Sign of a Bigger Problem?

The presence of flies in your home can indeed indicate underlying issues that need to be addressed. According to a study by the National Pest Management Association, in June 2024, many pest infestations start with seemingly minor fly problems, which then escalate if ignored.

3.1. Sanitation Issues

A fly infestation often points to inadequate sanitation practices, such as infrequent garbage disposal or unclean surfaces.

Poor Waste Management: Improper disposal of food waste and garbage can create breeding grounds for flies.
Unclean Surfaces: Dirty countertops and floors provide food sources and attract flies.
Lack of Hygiene: Insufficient cleaning practices can exacerbate fly problems.

3.2. Hidden Decay

Blow flies, in particular, are attracted to decaying organic matter, which might indicate a dead animal in or around your home.

Dead Animals: A dead rodent, bird, or other animal in the walls or attic can attract blow flies.
Unattended Meat: Spoiled meat left in the trash can also be a source of attraction.

3.3. Plumbing Problems

Drain flies thrive in moist environments with organic buildup, suggesting potential issues with your plumbing system.

Leaky Pipes: Leaking pipes create damp conditions that favor drain fly breeding.
Clogged Drains: Accumulation of food particles in drains provides a food source for drain flies.
Septic System Issues: Problems with the septic system can also lead to drain fly infestations.

3.4. Entry Points

Persistent fly problems may indicate that there are undiscovered entry points in your home, such as cracks or holes in screens or around windows and doors.

Damaged Screens: Torn or poorly fitted window and door screens allow flies to enter easily.
Cracks and Gaps: Cracks in the foundation or gaps around pipes and vents provide access points.
Open Doors and Windows: Leaving doors and windows open without screens can invite flies inside.

4. How Do Flies Find Their Way Into Homes?

Flies are adept at finding their way into homes through various entry points, using their strong senses and small size to their advantage.

4.1. Openings and Entry Points

Flies can enter through even the smallest openings in your home’s structure.

Doors and Windows: Open doors and windows are the most obvious entry points, especially if they lack screens.
Cracks and Gaps: Cracks in the foundation, walls, and around pipes provide easy access.
Vents: Unscreened vents, such as those for dryers or bathrooms, can be pathways for flies.

4.2. Attraction to Light and Odor

Flies are attracted to both light and odors emanating from your home.

Light: Flies are often drawn to indoor lights, especially at night, leading them to openings.
Odors: The smell of food, garbage, or decaying matter can attract flies from a distance.

4.3. Hitchhiking

Flies can also enter your home by hitchhiking on objects or materials brought inside.

Groceries: Flies can be transported inside on fruits, vegetables, or other grocery items.
Plants: Potted plants can harbor fly eggs or larvae in the soil.
Pets: Flies can be carried inside on pets, especially if they spend time outdoors.

5. Why Do Flies Keep Coming Back Even After Being Shipped Away?

Flies are persistent pests, and their return even after being removed is due to a combination of factors.

5.1. Remaining Attractants

If the underlying attractants are not eliminated, flies will continue to be drawn back to your home.

Unresolved Food Sources: Lingering food spills or uncovered garbage will continue to attract flies.
Breeding Sites: Untreated breeding sites, such as drains or moist areas, will produce new flies.
Persistent Odors: Unaddressed odors from decaying matter will continue to lure flies in.

5.2. Breeding Cycle

Flies have a rapid breeding cycle, meaning that even if adult flies are eliminated, eggs and larvae may still be present.

Short Life Cycle: Flies can complete their life cycle in as little as a week, leading to rapid population growth.
Hidden Eggs and Larvae: Eggs and larvae can be hidden in drains, garbage cans, and other hard-to-reach places.

5.3. External Sources

Flies can also come from external sources outside your home, such as neighboring properties or nearby garbage dumps.

Proximity to Breeding Sites: Living near a farm, landfill, or other breeding site increases the likelihood of fly infestations.
Migration: Flies can migrate from nearby areas in search of food and shelter.
