1. Understanding Why Flies Invade Your Home

Flies enter your house primarily in search of food, shelter, and warmth; according to research from the University of Florida, house flies are attracted to decaying organic matter, making garbage and compost prime targets. Anything sweet or easily accessible will definitely attract flies.

1.1. Why Are Flies Attracted to Homes?

Flies are attracted to homes for several reasons, including the availability of food sources, shelter from the elements, and suitable breeding grounds.

Food Sources: Open food containers, spills, and crumbs provide easy meals for flies.
Shelter: Homes offer protection from predators and harsh weather conditions.
Breeding Grounds: Moist areas like drains and garbage cans can become breeding sites.

1.2. What Smells Attract Flies?

Flies have a keen sense of smell, guiding them to potential food sources.

Garbage: The odor of decaying food in garbage cans is a strong attractant.
Pet Waste: Animal feces are irresistible to many fly species.
Sweet Substances: Spilled soda, fruit juices, and other sweet liquids lure flies inside.

1.3. Seasonal Fly Activity

Fly activity often spikes during specific seasons due to temperature and breeding cycles.

Spring: As temperatures rise, flies become more active and begin to reproduce.
Summer: Warm weather provides ideal conditions for fly breeding and foraging.
Fall: Flies may seek shelter indoors as temperatures drop.

2. Common Entry Points for Flies

Flies exploit various openings to gain access to your home. Identifying and sealing these entry points is essential for prevention.

2.1. Open Doors and Windows

Unscreened or improperly sealed doors and windows are primary entry points.

Gaps: Even small gaps around doors and windows can allow flies to enter.
Screens: Damaged or missing screens offer no barrier to flying insects.
Pet Doors: Pet doors can also serve as entry points if not properly maintained.

2.2. Damaged or Missing Screens

Screens with holes or tears provide easy access for flies.

Inspection: Regularly inspect screens for damage and repair them promptly.
Material: Choose durable screen materials that can withstand wear and tear.
Installation: Ensure screens are properly installed and fit snugly in the frame.

2.3. Cracks and Gaps in the Structure

Flies can squeeze through tiny cracks and gaps in your home’s structure.

Foundation: Check the foundation for cracks and seal them with caulk.
Siding: Inspect siding for gaps and repair any damage.
Utilities: Seal openings around pipes and wires entering the house.

2.4. Plumbing Systems and Drains

Drains and plumbing systems can serve as breeding grounds and entry points for certain types of flies.

Drain Flies: These small flies breed in the moist organic matter that accumulates in drains.
Sewer Gases: Cracks in drain pipes can allow sewer gases and flies to enter your home.
Maintenance: Regularly clean drains and ensure proper ventilation to prevent infestations.

3. Types of Flies Commonly Found in Homes
