Do Fruit Fly Traps Work On Gnats? Yes, fruit fly traps can work on gnats, but their effectiveness depends on the type of gnat and the specific attractant used in the trap. This comprehensive guide will help you understand the differences between fruit flies and gnats, the effectiveness of various traps, and how to get rid of these pests for good, all while highlighting how flyermedia.net can assist you with your pest control needs.
1. Understanding the Difference: Fruit Flies vs. Gnats
It’s crucial to identify your tiny flying invaders correctly. Fruit flies and gnats are often mistaken for each other, but understanding their differences is the first step to effective pest control.
1.1. Fruit Flies: The Overripe Fruit Fanatics
Fruit flies (Drosophila melanogaster) are small flies, typically about 1/8 inch long, with red eyes and a tan or brownish body. They are strongly attracted to ripe, rotting, or fermenting fruits and vegetables. You’ll often find them hovering around fruit bowls, garbage cans, and spilled drinks.
1.2. Gnats: A More Diverse and Annoying Bunch
Gnats are a broader category encompassing several species of small, two-winged flies. Here are some common types:
- Fungus Gnats: These dark-colored gnats are about 1/8 inch long and thrive in moist soil, feeding on fungi and decaying organic matter. They are often found near houseplants.
- Drain Flies (also known as Moth Flies): These small, fuzzy, dark-colored flies are about 1/5 inch long and breed in drains, sewers, and septic tanks.
- Biting Gnats (No-See-Ums): These tiny gnats are notorious for their painful bites. They breed in marshes, swamps, and other wet areas.

1.3. Key Differences Summarized
| Feature | Fruit Flies | Gnats (Fungus Gnats) | Gnats (Drain Flies) | Gnats (Biting Gnats) |
|---|---|---|---|---|
| Attraction | Overripe fruit, fermenting substances | Moist soil, fungi, decaying matter | Drains, sewers, septic tanks | Blood |
| Appearance | Red eyes, tan/brownish body | Dark-colored | Small, fuzzy, dark-colored | Tiny |
| Size | 1/8 inch | 1/8 inch | 1/5 inch | Varies |
| Habitat | Kitchens, fruit bowls, garbage areas | Houseplants, gardens, damp areas | Bathrooms, kitchens, plumbing systems | Marshes, swamps |
| Primary Issue | Annoyance, potential food contamination | Annoyance, plant damage (larvae) | Annoyance, potential contamination | Painful bites |
2. How Fruit Fly Traps Work
Fruit fly traps typically use a sweet, fermenting attractant to lure the flies into a container from which they cannot escape.
2.1. Common Trap Designs
- Jar with Funnel: A jar filled with apple cider vinegar and a drop of dish soap, covered with a funnel that allows flies in but makes it difficult to exit.
- Plastic Wrap Trap: A container with sweet liquid covered tightly with plastic wrap. Small holes are poked in the wrap for flies to enter.
- Commercial Traps: Many commercial traps are available, often using a pre-made liquid attractant.
2.2. The Science Behind the Attraction
Fruit flies are highly attracted to the smell of fermentation, which signals the presence of ripe or rotting fruit. Apple cider vinegar is a common attractant because it mimics this scent. The addition of dish soap breaks the surface tension of the liquid, causing the flies to drown once they land.
3. Effectiveness of Fruit Fly Traps on Gnats
Whether fruit fly traps work on gnats depends largely on the type of gnat. Here’s a breakdown:
3.1. Fungus Gnats
Fruit fly traps are generally not very effective for fungus gnats. Fungus gnats are primarily attracted to moist soil and fungi, not the sweet, fermenting scents that attract fruit flies.
3.2. Drain Flies
Fruit fly traps are unlikely to be effective for drain flies. Drain flies are attracted to the organic matter and bacteria found in drains, not fruit or vinegar.
3.3. Other Types of Gnats
For biting gnats, fruit fly traps are completely ineffective. Biting gnats are attracted to carbon dioxide and body odors, as well as the blood of mammals, which is their food source.
4. Best Solutions for Getting Rid of Gnats
Since fruit fly traps aren’t always the answer, here are some proven strategies for tackling gnat infestations.
4.1. Fungus Gnat Control
Fungus gnats require a multi-pronged approach targeting both adults and larvae:
- Reduce Moisture: Allow the top inch or two of soil in houseplants to dry out between waterings. Fungus gnat larvae thrive in moist conditions.
- Use Yellow Sticky Traps: Place yellow sticky traps near houseplants to catch adult fungus gnats.
- Apply Bacillus thuringiensis israelensis (Bti): This biological insecticide is safe for plants and pets but deadly to fungus gnat larvae. It’s available in mosquito dunk form. Simply soak the dunk in water and use the water to irrigate your plants.
- Repot Plants: If the infestation is severe, repot plants with fresh, sterile potting mix to eliminate larvae and eggs.
- Diatomaceous Earth: Sprinkle diatomaceous earth on the soil surface. It dehydrates and kills the larvae.
According to research from Cornell University, reducing moisture in the soil is the most effective way to control fungus gnats.
4.2. Drain Fly Control
Eliminating drain flies involves cleaning and disinfecting their breeding grounds:
- Clean Drains: Use a stiff brush or drain snake to scrub the inside of drains, removing organic matter and buildup.
- Use Enzyme Cleaners: Apply enzyme-based drain cleaners to break down organic matter. Avoid harsh chemical drain cleaners, as they can be harmful to the environment and ineffective against drain flies.
- Pour Boiling Water: Periodically flush drains with boiling water to kill larvae and eggs.
- Monitor Drain Activity: Cover drains with clear tape overnight. If drain flies are present, they will get stuck on the tape.
4.3. Biting Gnat Control
Controlling biting gnats requires protecting yourself and reducing breeding sites:
- Use Insect Repellent: Apply insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
- Wear Protective Clothing: Wear long sleeves, long pants, and a hat when outdoors, especially during peak biting times (dawn and dusk).
- Eliminate Standing Water: Remove standing water from your property, as it provides breeding sites for biting gnats.
- Use Fans: Biting gnats are weak fliers. Using fans can help keep them away.
- Consider Professional Pest Control: For severe infestations, professional pest control services may be necessary.

5. DIY Gnat Traps That Actually Work
If you’re looking for alternatives to fruit fly traps, here are some effective DIY gnat traps:
5.1. The Wine Trap
Gnats, particularly fruit flies, are attracted to the sweet and fermenting scent of wine. Leave a small amount of wine in a bottle with a narrow neck. The gnats will fly in but struggle to get out.
5.2. The Bleach Trap
Warning: Bleach is hazardous. Use carefully and keep out of reach of children and pets.
Pour a small amount of diluted bleach into the drain where you suspect drain flies are breeding. This can kill larvae and adults.
5.3. The Apple Cider Vinegar and Dish Soap Trap (Modified)
While plain apple cider vinegar might not attract fungus gnats, adding a few drops of liquid dish soap to a mixture of apple cider vinegar and water can help trap them. The soap breaks the surface tension, causing the gnats to sink and drown.
5.4. The Potato Trap
For fungus gnats, a potato trap can be effective. Place a slice of raw potato just below the surface of the soil in your houseplants. The larvae will be attracted to the potato as a food source. After a few days, remove the potato and dispose of it, along with the larvae.
6. Preventing Future Infestations
Prevention is key to keeping gnats away for good.
6.1. Indoor Prevention
- Maintain Cleanliness: Regularly clean kitchen counters, sinks, and floors to eliminate food debris and spills.
