Why Homemade Fly Traps Are Your New Best Friend
Why bother with a homemade fly catcher for indoors when there are so many products on the market? Well, for starters, you likely have most of the ingredients already in your kitchen! It’s a fantastic way to repurpose common items and avoid buying single-use plastic traps. Plus, you control exactly what goes into your trap, making it a safer option for homes with children or pets. And let’s be honest, there’s a real satisfaction in solving a problem with something you made yourself! It’s kind to your wallet and kind to the planet.
Understanding Your Uninvited Guests: Common Indoor Flies
Before we start building traps, it’s helpful to know who you’re dealing with. Different flies are attracted to different things, and understanding their preferences can make your homemade traps even more effective.
| Type of Fly | Common Attractants | Where They Originate |
|---|---|---|
| Fruit Flies | Fermenting fruits, vegetables, sugary drinks, alcohol, drains | Overripe produce, garbage disposals, damp areas |
| House Flies | Garbage, decaying organic matter, pet waste, sugary substances | Outdoor garbage cans, compost piles, animal droppings; they find their way in |
| Drain Flies (Filter Flies) | Organic slime in drains, damp areas, sewage | Clogged drains in bathrooms and kitchens, leaky pipes |
| Fungus Gnats | Moist soil, decaying plant matter | Houseplants, especially those kept too wet |
Knowing these common attractants is the first step to creating a targeted and effective homemade fly catcher for indoors.
DIY Homemade Fly Catcher Method 1: The Classic Cone Trap
This is probably the most common and effective DIY fly trap, especially for fruit flies and house flies. It’s simple, uses readily available materials, and works on the principle that flies can get in, but they can’t easily get out.
What You’ll Need:
A jar or a plastic bottle (a soda bottle works great)
A piece of paper or thin cardboard
Tape
Scissors
A bait:
For fruit flies: a small amount of apple cider vinegar with a drop of dish soap. A piece of overripe fruit also works wonders!
For house flies: a small amount of honey, sugar water, or a tiny bit of meat or fish.
For fungus gnats: a small amount of apple cider vinegar or just plain water.
Step-by-Step Instructions:
1. Prepare Your Container: If you’re using a plastic bottle, cut off the top third of the bottle. If you’re using a jar, you’ll just need the opening.
2. Add Your Bait: Place your chosen bait in the bottom of the jar or the main part of the plastic bottle.
For vinegar-based baits, add the vinegar first, then a drop or two of liquid dish soap. The soap breaks the surface tension, so flies sink and drown.
For fruit or meat baits, place them directly in the container.
3. Create the Funnel: Take your piece of paper or cardboard and roll it into a cone shape. Make sure the opening at the point of the cone is quite small – just big enough for a fly to enter.
4. Assemble the Trap: Place the paper cone into the opening of your jar or bottle. The tip of the cone should be pointing downwards but shouldn’t touch the bait. You want to leave a small gap for flies to enter.
5. Secure It: Use tape to secure the paper cone to the sides of the jar or bottle. This prevents flies from escaping around the edges. If you used a plastic bottle, you might want to tape the cut-off top section (inverted) to create the funnel.
6. Place Your Trap: Position your homemade fly catcher where you see the most fly activity. Near fruit bowls, windows, trash cans, or kitchen sinks are good spots.
This simple design effectively lures flies in with the scent of the bait, they then get confused by the narrow opening of the cone and struggle to find their way out, eventually getting trapped.
DIY Homemade Fly Catcher Method 2: The Sticky Ribbon Trap
While not strictly “homemade” in the sense of building a device, you can create your own version of sticky fly paper using common household ingredients. This is effective for catching house flies and other flying insects that land on surfaces.
What You’ll Need:
A strip of parchment paper or sturdy brown paper bag
A bowl or shallow dish
Sugar
Corn syrup or honey
A wooden skewer or string for hanging
Step-by-Step Instructions:
1. Prepare the Sticky Mixture: In a bowl, mix roughly equal parts sugar and corn syrup (or honey). You want a thick, sticky paste. If it’s too runny, add more sugar. If it’s too stiff, add a little more syrup or honey.
2. Coat the Paper: Lay out your strip of parchment paper or cut a strip from a brown paper bag. Spread the sticky mixture evenly over one side of the paper, leaving a small border around the edges.
3. Add a Hanger: If you plan to hang your trap, attach a string or wooden skewer to one end of the paper strip before it gets too sticky. You can poke a hole and tie a string, or tape a skewer securely along one edge.
4. Position Strategically: Hang the sticky strip in areas where flies are a problem but out of reach of children and pets. Areas near windows or sunny spots can be good, as warmth can make the mixture slightly tackier.
5. Dispose and Replace: Once the sticky paper is covered in flies or no longer sticky, carefully roll it up and discard it. Then, make a new one!
This method relies on the flies landing on the sticky surface and getting stuck. It’s a visual and effective way to reduce fly populations.
DIY Homemade Fly Catcher Method 3: The Vinegar & Dish Soap Lure
This is a super simple trap, perfect for fruit flies and drain flies, and requires no construction at all! It focuses on luring flies to their doom in a liquid trap.
What You’ll Need:
A small bowl, glass, or even a repurposed jar lid
Apple cider vinegar (experiment with other vinegars or fruit juices if you don’t have ACV; flies love fermented smells!)
Liquid dish soap
Optional: a piece of overripe fruit as an extra attractant
Step-by-Step Instructions:
1. Pour the Attractant: Pour about an inch of apple cider vinegar into your chosen container.
2. Add the Soap: Add a drop or two of liquid dish soap. This is crucial! It breaks the surface tension of the vinegar. Flies will land, thinking they can drink, but they’ll sink and drown because the soap prevents them from staying afloat.
3. Boost the Scent (Optional): If you have a bit of overripe fruit (like a slice of banana or apple), you can add it to the vinegar to make the scent even more enticing.
4. Place It: Put these small traps in areas where you notice fruit flies or drain flies congregating – near the fruit bowl, by the sink, or in the bathroom.
5. Refresh Regularly: Empty and refill the traps every few days, or as needed, once they start catching flies.
This trap is incredibly effective for tackling those tiny, persistent fruit flies that seem to appear from nowhere.
What About That Lingering Smell? Dealing with Fungus Gnats
Fungus gnats are tiny, dark flies that often hang around houseplants. They’re not harmful to humans, but they can be annoying and are a sign your plant’s soil might be too wet. While the vinegar traps can work for them, there are even simpler methods.
Yellow Sticky Traps: These are commercially available, but you can make a DIY version by sticking yellow cardstock (flies are attracted to yellow) into the soil of your plants, coated with a thin layer of petroleum jelly. Ensure it’s placed so pets can’t reach it.
The Ice Trick: For persistent fungus gnats, water your plants thoroughly, then place a layer of ice cubes on top of the soil. As the ice melts, it lowers the soil temperature, which kills the gnat larvae. Let the soil dry out almost completely before watering again. This can help break the life cycle.
Diatomaceous Earth: Food-grade diatomaceous earth (DE) is a natural powder made from fossilized aquatic organisms. It has sharp edges that dehydrate insects. lightly dust the top layer of your plant’s soil with DE to kill gnats. Always use food-grade DE and avoid inhaling the dust. For more information on safe and effective pest control, the Environmental Protection Agency (EPA) offers great resources on integrated pest management.
Troubleshooting Your Homemade Fly Catcher
Even the best homemade fly catcher for indoors might need a little tweaking. Here are some common issues and solutions:
Not Catching Enough Flies:
Bait: Is your bait appealing? Try a different scent. For fruit flies, overripe fruit is often better than just vinegar. For house flies, something a bit richer like a touch of meat or fish in a separate, sealed trap might be necessary.
Placement: Are you putting the trap where the flies are actually congregating? Try moving it closer to their known hangouts.
Seal: Is your trap well-sealed? Flies are attracted to entry points and can sometimes squeeze through tiny gaps. Ensure the cone or lid is secured tightly.
Flies Escaping:
Cone Opening: Make sure the tip of your paper cone is small enough. Flies can sometimes exit if the opening is too wide.
Sticky Surface: For sticky traps, ensure the surface is consistently sticky. Reapply the mixture if it dries out or becomes ineffective.
Attracting More Flies (Not Trapping Them):
Hygiene: Make sure your trash is taken out regularly, dishes are washed promptly, and any spills are cleaned up. Your traps work best when there are fewer alternative food sources available.
Placement: Sometimes, a trap placed too close to a window or door might just be attracting more flies from outside. Try moving it deeper into the room.
Prevention is Key: Beyond the Homemade Fly Catcher
While homemade fly catchers are excellent for eliminating existing pests, preventing them from entering your home in the first place is always the best strategy for a fly-free environment.
Tips for Prevention:
Seal Entry Points: Check windows and doors for gaps or tears in screens. Use weatherstripping or caulk to seal any openings where insects can enter.
Manage Moisture: Flies, especially drain flies, are attracted to damp areas. Fix leaky pipes, ensure good ventilation in bathrooms, and don’t let water stand in sinks or on counters.
Garbage Management: Keep kitchen trash cans sealed tightly and empty them regularly. Clean out trash cans periodically to remove any residue that might attract flies.
Food Storage: Store fruits and vegetables in sealed containers or the refrigerator. Don’t leave food sitting out, especially sugary items or leftovers.
* Cleanliness: Regularly clean surfaces, especially in the kitchen. Wipe up spills immediately, and wash dishes promptly. Pay attention to areas like garbage disposals where food particles can accumulate. Resources from university extension offices, like those found at Michigan State University Extension, often provide excellent, science-backed pest prevention tips.
