Types of Gnats 

1. Fungus Gnats 

Fungus gnats are small black insects with long legs. They favor damp, overwatered houseplant soil, especially one with rotting plant matter. They then lay eggs, whose larvae feast on plant roots. This often turns leaves yellow, causes wilting, and could even kill the plant. 

2. Fruit Flies 

Round and brown, fruit flies love ripe or rotting fruits and veggies. They deposit their eggs on these food sources, making them spoil faster. They can also contaminate any area they land on. 

3. Drain Flies 

Also known as sewer flies, these fuzzy, moth-like bugs prefer humid spots like drains, garbage disposals, and sink pipes. Their larvae thrive in the decaying organic matter and moisture in these environments. 

The table below gives a snapshot of each type’s description. 

Studies have shown that there is no permanent remedy for gnats but taking some measures for the long term eradication of gnats such as removing areas where breeding occurs, such as wet spots or stagnant water, might help in getting rid of gnats.

How to Identify Gnats 

Each gnat type has distinct looks and behaviors. Recognizing the kind of gnat in your home will help pick effective gnat-busting methods. 

The table below helps pin down their appearance specifics. 

Where are Gnats Usually Found 

Depending on the type, gnats favor different parts of homes and gardens: 

• Fungus gnats: Around over-watered houseplants and damp soil 
• Fruit flies: Close to fruit bowls, trash bins, and spoiled fruits and veggies 
• Drain flies: In and around drains, garbage disposals, and sink pipes 

Signs of Gnat Infestation 

Infested by gnats? One clear sign is many flying bugs in the affected areas. While they don’t hurt wood or leave feces trails, it’s important to manage infestations quickly. This prevents plant harm and possible human health risks. 

Here’s a summary of the infestation indicators to watch out for: 

If you do not know, then let me shed some light upon ‘gnats’. Gnats are small, non-biting flies or insects that usually grow in polluted water, wet soil, or seepage. There is no permanent solution to get rid of them but pressurised aerosols containing pyrethrin may help to a great extent.

Different Methods to Get Rid of Gnats 

There are several solutions to get rid of gnat problems, from DIY activities to professional services. 

Indoor Solutions 

1. Making a Gnat Trap 

Homemade gnat traps can help control these pests indoors. Try the two popular ones below: 

2. Vinegar and Sugar 

Mix apple cider vinegar, sugar, and dish soap in a bowl. Place this bowl in the affected area. The smell attracts gnats, the soap catches them, and the vinegar kills them. 

3. Rotten Fruit Trap 

Put a rotting fruit piece in a big bowl. Cover the bowl with plastic wrap and secure it with a rubber band. Poke some holes in the wrap with a toothpick. Gnats will fly towards the fruit, but the trap will stop them from escaping. 

4. Flypaper 

Hang sticky ribbons in places with a lot of gnat activity. These can help catch and kill them. Change the flypaper when it’s full of trapped bugs. 

5. Bug Zappers 

Try an indoor-safe bug zapper for a quick and effective gnat solution. These devices use electric shocks to kill gnats on contact. 

6. Chemical Sprays 

If the infestation is severe, you may need to use chemical sprays. Remember to follow the instructions carefully. Also, make sure to keep these products away from kids and pets. 

7. Boiling Water for drains 

Pouring boiling water down your kitchen sink drain can aid in killing gnat eggs and larvae. This will also clear food and bacteria buildup that draws these insects. 

8. Wine Trap 

Near-expired or turned wine can also help trap gnats. Pour some stale wine into a small container, add a bit of dish soap, and place it in gnat-heavy areas. Gnats will flock to the wine and get trapped. 

9. Candle Trap 

Set a tall candle in a candlestick in a small water-filled pan. Light the candle and switch off other lights. Gnats will either fly into the flame and burn or fall into the water and drown. 

10. Setting up a Candle Trap 

Follow these steps to set up a candle trap: 

1. Fill a small pan with water and a bit of dish soap. 

2. Place a candlestick in the water. 

3. Put a tall candle in the candlestick. 

4. Light the candle and turn off all other lights. 

5. Wait for gnats to be drawn to the flame and meet their end. 

Remember to stay in the room while the candle is burning and put it out when you’re done. 

11. Cleaning Drains with Diluted Bleach 

Clean the drains with a diluted bleach solution, that is,  one part bleach to two parts water. Wearing safety gear and ventilating the room is a must when working with bleach. 

12. Houseplant Solutions 

Gnats love houseplants. But don’t worry, the following remedies can help: 

13. Sticky Cards 

Place sticky cards (bright cards covered with glue) near the affected plants. These will trap and kill gnats. 

14. Food-grade Diatomaceous Earth 

Dust the dry, infected plant soil with food-grade diatomaceous earth. The armed powder will catch gnats and dehydrate them to death. 

15. Soil Drenching 

Try a Bacillus thuringiensis israelensis (Bti) drench on the infested plant soil. It’s a safe bacterium that kills gnat larvae without causing plant harm. 

16. Allowing Plants to Dry Out 

Give plants a break between waterings to cut off a moist breeding ground for gnats. 

17. Repotting Plants 

If gnats keep coming back, you can move infested plants to clean pots filled with fresh potting soil. 

Outdoor Solutions 

1. Yellow Sticky Traps 

Place yellow sticky traps around outdoor plants. The bright color will catch fungus gnats’ attention and trap them. 

2. Food-grade Diatomaceous Earth for Gardens 

Use food-grade diatomaceous earth around garden plants. It will trap and kill gnats. 

3. Fungus Gnat Control in the Garden 

Use a Bacillus thuringiensis israelensis (Bti) drench in your garden. It will kill gnat larvae without affecting garden plants or animals. 

This precise table sums up the above-mentioned gnat control measures. 

Lowering the Occurrence of Gnat Infestations 

To lower the risk of a gnat infestation at your home, follow these quick tips: 

Indoors  

1. Maintain Low Humidity in Your Home 

Use room vents and dehumidifiers to cut down moisture levels at home. Remember, gnats love moist places. 

2. Proper Trash Management 

Close trash bins with secure lids. And dispose of indoor waste often to keep gnats away from their food source. 

3. Avoid Overwatering Houseplants 

Allow plants to dry in between watering to reduce moisture that gnats are drawn to. 

4. Keeping Drains Clean and Dry 

Always clean drains and garbage disposals. Use a drain cover overnight to keep moist areas gnat-free. 

Outdoors  

1. Proper Garden Maintenance 

Keep gardens clean and free of rotten plants to deprive gnats of breeding spots. 

2. Regular Cleaning of Outdoor Spaces 

Clean outdoor trash bins and minimize water collection spots. This will cut down gnat breeding near your home. 

Here’s a quick guide to what to do to prevent gnats:
