Where Can Flies Be Coming From In My House is a common question, and understanding the answer is crucial for maintaining a healthy and comfortable home, and flyermedia.net is here to give you the answer. Flies can enter your home through various entry points, thrive on readily available food sources, and seek shelter from extreme weather. By identifying these sources and implementing preventive measures, you can effectively control fly populations.
1. Understanding the Common House Fly
1.1. The Lifecycle of a Housefly
Understanding the lifecycle of a housefly is crucial in tackling infestations effectively. The transformation from egg to adult is quick, especially in warm conditions, as stated by the University of Florida’s Entomology Department.
| Stage | Duration | Description |
|---|---|---|
| Egg | 8-20 hours | Flies lay their eggs in decaying organic matter such as garbage, feces, or rotting food. |
| Larva | 4-7 days | Also known as maggots, larvae feed voraciously on the organic material where they were laid. They molt twice during this stage. |
| Pupa | 4-10 days | The larva transforms into a pupa inside a hardened case. This stage is similar to a cocoon in butterflies. |
| Adult | 15-30 days (avg.) | The adult fly emerges from the pupal case. It is capable of flying and reproducing almost immediately. Adult flies feed on a variety of substances and can lay hundreds of eggs in their short lifetime. |
1.2. Identifying Common Houseflies
The typical housefly is dark gray, between 1/8” to 1/4” long, has six legs and antennae, and has a small, oval body, and two wings that overlap on their back. Houseflies are found throughout the U.S. The larvae are maggots—those creamy white-gray rice-like critters that you see wiggling around on an old banana peel in the garbage.
1.3. What Attracts Flies to Your Home?
Flies are attracted to homes by the promise of food, water, and shelter. According to the Environmental Protection Agency (EPA), these pests thrive on decaying organic matter, making garbage cans, compost piles, and pet waste prime attractants.
2. Common Entry Points for Flies
2.1. Open Doors and Windows
Do flies come in through open windows? Flies can easily enter through open doors and windows, especially if there are no screens or if the screens are damaged.
2.2. Damaged Screens
How do flies get in if windows are closed? Damaged screens are an open invitation for flies. Even small holes or tears can provide easy access.
2.3. Cracks and Gaps
Flies can squeeze through tiny cracks and gaps around doors, windows, vents, utilities, or sealed pipes. Sealing these entry points is crucial, as noted in a study by the National Pest Management Association (NPMA).
2.4. Plumbing Systems
Drain flies breed in the moist organic matter that accumulates in drains. These flies are small and can quickly become a nuisance if not addressed.
2.5. Following Scents
How are flies getting in my house all of a sudden? Flies have a strong sense of smell and can follow scents of pet food, garbage, or outdoor cooking areas into your home.
3. Inside the House: Fly Hotspots
3.1. Kitchen Areas
Kitchens are prime locations for flies due to the availability of food scraps, spills, and open garbage containers.
3.2. Bathrooms
Bathrooms can attract flies due to moisture and organic matter in drains and toilets. Drain flies, in particular, thrive in these conditions.
3.3. Basements
Basements, especially those with moisture issues, can provide breeding grounds for flies. Standing water and damp organic materials are ideal for fly larvae.
3.4. Indoor Plants
Overwatered indoor plants can attract fungus gnats, a type of small fly that breeds in moist soil.
4. Outside the House: External Sources
4.1. Garbage and Recycling Bins
Uncovered or poorly maintained garbage and recycling bins are breeding grounds for flies. Flies lay their eggs in the decaying matter, leading to rapid population growth.
4.2. Compost Piles
Compost piles, while beneficial for gardening, can also attract flies if not managed properly. Covering the compost and ensuring proper decomposition can help reduce fly attraction.
4.3. Pet Waste
Pet waste left in the yard is a significant attractant for flies. Regular cleanup is essential for controlling fly populations.
4.4. Gardens and Yards
Overripe fruits and vegetables in gardens, as well as poorly maintained yards, can provide food and breeding sites for flies.
5. Types of Flies Commonly Found Indoors
5.1. House Flies
House flies are the most common type of fly found in homes. They are attracted to garbage, food waste, and other decaying organic matter.
5.2. Fruit Flies
Fruit flies are small flies that are attracted to ripe or fermenting fruits and vegetables. They are often found near fruit bowls, kitchen counters, and garbage disposals.
5.3. Drain Flies
Drain flies, also known as moth flies, are small, fuzzy flies that breed in drains and sewers. They are often seen in bathrooms and kitchens.
5.4. Cluster Flies
Cluster flies are larger than house flies and are often found in attics and other dark, secluded areas. They enter homes in the fall to overwinter.
6. Health Risks Associated with Flies
6.1. Disease Transmission
Do house flies spread disease? Yes, house flies can transmit over 100 pathogens, including bacteria, viruses, and parasites. They pick up these pathogens from garbage, feces, and other contaminated sources.
6.2. Contamination of Food
Flies can contaminate food by landing on it and depositing pathogens. This can lead to food poisoning and other illnesses.
6.3. Allergic Reactions
Some people may experience allergic reactions to flies, particularly to their saliva or feces. These reactions can manifest as skin rashes, itching, or respiratory problems.
7. Preventative Measures to Keep Flies Away
7.1. Maintaining Cleanliness
Keeping a clean house is the first line of defense against flies. Regularly cleaning kitchens, bathrooms, and other areas can eliminate potential food sources and breeding sites.
7.2. Proper Waste Management
Proper waste management is crucial for preventing fly infestations. This includes using trash cans with tight-fitting lids, regularly emptying trash, and cleaning garbage and recycling bins.
7.3. Sealing Entry Points
Sealing cracks and gaps around doors, windows, and utilities can prevent flies from entering your home. Use caulk or weather stripping to seal these entry points.
7.4. Using Window Screens
Installing and maintaining window screens can keep flies out while allowing fresh air to circulate. Ensure that screens are free of holes and tears.
7.5. Managing Outdoor Areas
Managing outdoor areas, such as gardens and yards, can reduce fly populations. Remove overripe fruits and vegetables, clean up pet waste, and maintain compost piles properly.
8. Natural Fly Control Methods
8.1. Using Essential Oils
Essential oils, such as peppermint, eucalyptus, and lavender, can repel flies. Dilute essential oils with water and spray around your home.
8.2. Homemade Fly Traps
Homemade fly traps can be an effective way to catch and kill flies. A simple trap can be made using a jar, apple cider vinegar, and dish soap.
8.3. Fly-Repelling Plants
Certain plants, such as basil, mint, and lavender, can repel flies. Place these plants near doors and windows to deter flies from entering.
8.4. Biological Controls
Spiders and wasps are natural predators of flies. Encouraging these beneficial insects in your yard can help control fly populations.
9. Chemical Fly Control Methods
9.1. Fly Sprays
Fly sprays can quickly kill flies but should be used with caution. Follow the manufacturer’s instructions and avoid spraying near food preparation areas.
9.2. Fly Baits
