How to Get Rid of Flies in the House
When we’re battling flies in our homes, we’re essentially racing against their incredible reproduction rate. House flies are certainly one of the most common pests we encounter, often appearing in swarms during late summer to early fall. These pesky insects can enter through the tiniest gaps in windows and doors, making our lives miserable.
However, effective solutions exist to deal with this problem. From homemade traps using apple cider vinegar and dish soap to natural repellents like citronella, we have numerous options to combat these unwanted guests. Additionally, Venus flytraps can be used as a natural control method since they consume insects, including flies.
In this article, we’ll explore what attracts flies to our homes, natural remedies for immediate relief, commercial options for severe infestations, and prevention strategies to keep them from returning. Let’s discover the best way to get rid of flies in house environments and reclaim our pest-free spaces!
What Attracts Flies to Your Home
Understanding what attracts flies to your home is the first step toward effective control. Flies don’t appear randomly—they’re drawn to specific conditions that provide food, moisture, and breeding sites.
Common indoor attractants
Flies enter our homes primarily in search of food and suitable breeding grounds. Decaying organic matter is particularly appealing to house flies, while fruit flies are attracted to sugary substances and overripe produce. The kitchen often becomes a hotspot for fly activity because of:
• Uncovered garbage cans with food residue • Overripe fruits and vegetables left on countertops • Spilled sugary liquids like soda or alcohol • Food remnants in garbage disposals • Dirty drains with organic buildup
Furthermore, different fly species prefer specific indoor environments. Drain flies thrive in moist areas with organic buildup, particularly in bathroom and kitchen drains. Meanwhile, fruit flies seek fermenting material, making them common around kitchen waste and recycling bins containing unrinsed bottles.
Outdoor sources that lead flies inside
Your yard and surrounding areas can become launching points for flies to enter your home. Numerous outdoor attractants can bring flies closer to entry points:
Animal carcasses serve as powerful magnets for certain fly species, with a single dead animal potentially causing a quick escalation in fly numbers. Likewise, pet waste becomes an ideal breeding site, especially for house flies that prefer to lay eggs in feces.
Unsealed garbage containers and compost piles emit odors that attract flies from considerable distances. Once flies gather around these outdoor sources, they often find their way indoors through open doors and windows or other structural gaps.
Why flies multiply so quickly
The reproduction rate of flies is truly remarkable. A single female house fly can lay up to 500 eggs in her lifetime, depositing them in several batches of 75 to 150 eggs over a three to four day period. Under optimal conditions, scientists have calculated that a pair of flies beginning reproduction in April could theoretically produce 191,010,000,000,000,000,000 flies by August.
Temperature plays a crucial role in fly reproduction. At 60°F, house flies complete their life cycle in about 45 days, but at 95°F, this period shrinks dramatically to just 7 days. Consequently, warm summer conditions accelerate breeding cycles, explaining why fly populations seem to explode overnight.
The entire life cycle—from egg to adult—can be completed in as little as 7-10 days under ideal conditions. As a result, what begins as just one or two flies can quickly transform into a full-blown infestation if conditions remain favorable.
Natural Remedies to Get Rid of Flies
When pesky flies invade your home, natural remedies offer effective and immediate solutions without harsh chemicals. These approaches harness materials you likely already have on hand.
Using herbs and flowers as repellents
Flies actively avoid certain fragrant plants, making them excellent natural deterrents. Fresh basil tops the list as flies strongly dislike its aroma. Beyond basil, several other plants effectively repel these insects:
• Lavender – Its floral scent deters flies while adding a pleasant aroma • Rosemary – The strong herbal odor discourages flies and other pests • Mint – Repels flies, ants, and even mice • Marigolds – Their distinctive fragrance keeps flies at bay
Placing potted herbs near doorways, windows, or kitchen counters creates natural barriers against fly invasions. Moreover, these plants provide the added benefit of fresh herbs for cooking.
Apple cider vinegar and dish soap trap
This simple yet remarkably effective trap uses two basic ingredients. Pour approximately 1/4 cup of apple cider vinegar into a container, then add a few drops of liquid dish soap. The vinegar’s fermented scent attracts flies, while the soap breaks the liquid’s surface tension, causing flies to sink and drown instead of landing safely.
DIY soda bottle and cone traps
Transform an empty plastic bottle into a powerful fly trap. Cut the bottle in half, remove the cap, then place the top portion upside down inside the bottom half, creating a funnel. Fill the bottom with your bait (vinegar, fruit, or sweetened liquid), add a few drops of dish soap, then secure with tape. Alternatively, create a paper cone with a small opening at the bottom and place it in a jar containing bait. Both designs allow flies to enter but make escape nearly impossible.
Essential oils like eucalyptus and citronella
Essential oils provide another powerful weapon against flies. Citronella, eucalyptus, lavender, and peppermint oils all effectively repel these insects. Create a spray by adding a few drops of oil to water, or use an oil diffuser to distribute the scent throughout your home. Tea tree oil mixed with apple cider vinegar creates a particularly effective fly trap.
Chemical and Commercial Fly Control Options
For persistent fly infestations that resist natural remedies, commercial products offer powerful solutions. These options provide quick results for severe problems while giving you multiple approaches to tackle unwanted flies.
When to use pyrethrin-based sprays
Pyrethrin-based insecticides derive from chrysanthemum flowers, making them a bridge between natural and commercial solutions. These products effectively target the central nervous system of flies, providing rapid knockdown and kill. I recommend using these sprays when dealing with large fly populations that require immediate control.
Although pyrethrins have a low toxicity to humans and mammals, they should be used according to label instructions. The beauty of pyrethrin products lies in their dual action – they kill on contact and also repel flies, often causing survivors to exit through windows and doors. Pyrethrin sprays work especially well for controlling house flies, mites, thrips, and whiteflies in indoor environments.
How light traps and UV zappers work
Flies possess UV-sensitive photoreceptors that draw them toward ultraviolet light sources. Commercial UV traps exploit this attraction through two primary mechanisms:
• High-voltage zappers – Electrocute flies on contact but can scatter insect fragments up to 1.5 meters away, making them unsuitable for food preparation areas • Glue board light traps – Trap flies intact on adhesive surfaces, ideal for kitchens and dining spaces
Most effective traps are placed 3-5 feet above floor level where flies typically travel. For nighttime protection, ceiling-mounted traps positioned 8 feet above the floor capture nocturnal flying pests effectively.
Sticky traps and fly paper effectiveness
Despite their simplicity, sticky traps remain remarkably effective. Modern versions contain sugars and pheromone-based attractants that lure flies to adhesive surfaces. Fly papers work best in areas where flies congregate frequently – near windows, trash cans, and entrances.
The primary drawback of sticky traps is esthetic – hanging strips of flypaper might not suit all environments. Alternatively, discreet commercial options blend with décor while maintaining effectiveness.
How to Prevent Flies from Coming Back
Prevention remains the most effective strategy for long-term fly control. After addressing an active infestation, take these proactive steps to ensure flies don’t make a comeback in your home.
Seal entry points like windows and doors
First and foremost, create a physical barrier between your home and unwanted insects. Flies typically enter through tiny gaps around structural openings. Install fine mesh screens on windows and doors, ensuring they’re free from holes or tears. Apply weatherstripping to seal gaps around doors and windows, plus add door sweeps at the bottoms of exterior doors. For cracks in walls or foundations, use caulk—particularly around pipes, vents, and utility lines.
Proper food and garbage storage
Garbage management plays a crucial role in fly prevention. Use trash cans with tight-fitting lids and position them as far from building entrances as possible. Empty garbage containers at least once weekly in cooler months and twice weekly during summer. Store food in airtight containers, as unsealed items provide strong attractants. For pet food, use sealed containers and never leave wet pet food sitting out.
Cleaning routines that deter flies
Regular cleaning eliminates the conditions flies need to thrive. Promptly clean up spills, especially sugary substances. Wash dishes immediately rather than letting them accumulate in sinks. For drains—a common breeding site—create a cleaning solution using vinegar and baking soda to remove organic buildup. Additionally, clean outdoor garbage areas thoroughly, removing residue that might attract flies.
Outdoor lighting and pet waste management
Outdoor lighting significantly impacts fly presence. Most flying insects are attracted to blue and ultraviolet light, yet barely perceive yellow, amber, or red wavelengths. Replace outdoor bulbs with yellow “bug lights” or warm-colored LED options (2000K-3000K). For pet waste management, remove droppings daily, as a single deposit can attract numerous flies and provide ideal breeding conditions. Consider installing a pet waste disposal system that works like a mini septic tank for dog waste.
Conclusion
Dealing with flies requires a multi-faceted approach for lasting results. Throughout this guide, we’ve explored why these pests invade our homes, from food residue to outdoor attractants, and their remarkable ability to reproduce at alarming rates. Additionally, we’ve covered numerous effective solutions ranging from simple DIY traps with apple cider vinegar to commercial options like UV zappers.
Natural remedies certainly provide immediate relief without harsh chemicals. Flies absolutely detest herbs like basil and mint, making these plants excellent first-line defenses. For stubborn infestations, however, pyrethrin-based products offer quick knockdown power while sticky traps work tirelessly to reduce populations over time.
Prevention ultimately stands as the most effective strategy against these persistent pests. Properly sealed entry points, diligent cleaning routines, and strategic food storage all work together to create an unwelcoming environment for flies. Most importantly, addressing both indoor attractants and outdoor sources simultaneously yields the best results.
Remember, consistency proves key when battling flies. Their rapid reproduction means even small lapses in prevention can quickly lead to resurgence. Armed with these strategies, you can now reclaim your home from these unwanted visitors and enjoy a fly-free environment year-round!
