Gnats in the Kitchen and Dining Area

You are most likely dealing with fruit flies. The kitchen and dining area is usually the #1 spot where gnats and fruit flies appear inside the house due to the presence of rotten fruits and kitchen waste. Here are the elimination methods we suggest:

1. Keep the Kitchen Bin Tightly-Sealed

The kitchen bin is usually the #1 breeding ground for gnats and fruit flies, especially when the warmth of summer kicks in. If you don’t already have one, we suggest investing in a kitchen bin that comes with a tightly-sealed lid. One recommendation is the iTouchless stainless steel bin. Not even something as tiny as a gnat will be able to make its way into the kitchen waste.

In addition to investing in a solid bin, we would also suggest taking out the trash more regularly, at least when the weather is warm and humid.

2. Create Apple Cider or White Vinegar Traps

This is a super-easy DIY method for getting rid of gnats. Add a few spoons of apple cider vinegar, few drops of dish soap, and a tablespoon of sugar in an old bowl and mix the contents. White vinegar works as well but some of our readers have found it to be not as effective as apple cider vinegar.

To create the gnat vinegar trap, place one or two bowls near the part of the kitchen or dining area where the gnats swarm. Terro offers ready-made vinegar traps if you prefer to buy them.

Gnats in the Bathroom or Toilet

You are most likely dealing with sewer gnats or drain flies if they mostly appear from the bathroom or any part of the house that has drainage pipe openings. Here are the removal methods we suggest for these types of gnats.

3. Clean the Bathroom Drains

The dirty debris that accumulates in the bathroom drains is the perfect breeding ground for sewer flies and drain gnats. We suggest using drain treatment cleaners such as the Green Gobbler Gel to keep the pipes clean.

4. Dehumidify the Bathroom

This isn’t as easy for houses or apartments that have windowless bathrooms but it’s important to get rid of the excess moisture in the bathroom. This also applies to other parts of the house that has access to water. Moisture is one of few things that gnats are attracted to.

Get yourself a strong dehumidifier and turn it on during days of high humidity or just after you took a shower. Don’t forget to open the windows as well if the bathroom has them.

Gnats Near Houseplants or Garden

You are most likely dealing with fungus gnats. To kill fungus gnats, you need to locate the houseplants that are infested with the larvae and eggs.

5. Set Up Yellow Sticky Traps

Go buy some yellow sticky traps (they are inexpensive) and place them in the vicinity of the infested houseplant. Yellow sticky traps will also help with removing part of the infestation. It will get rid of the adult flies but it won’t get rid of the gnat larvae and eggs.

6. Apply Mosquito Bits to the Soil

To get rid of the gnat larvae and eggs in the soil, we would suggest using a product like Mosquito bits. You don’t have to worry about pesticide concerns as mosquito bits leverage a natural bacteria called BTi to kill the larvae.

How to Prevent a Gnat Infestation

Ultimately, there is nothing more effective to getting rid of gnats than to prevent them from appearing in the first place. We already offered a few hints on how that can be done.

Keep the Kitchen Meticulously Clean

In addition to taking out the trash regularly, make sure there is no food waste left in the open. Pay special attention to fruits and vegetables. Make sure to discard any that are showing signs of rotting.

Sanitize the Drains and Pipes

Aside from using gel-based drain treatment products, you can also keep the pipes clean by pouring down hot, boiling water once a day.

Don’t Overwater Your Plants

Overwatering is one of the biggest reasons why gnats start to appear from houseplant soil. Your plants will also thank you if you keep the watering at the minimum frequency.

    I tried the apple cider vinegar trap. It got some but not all of the gnats. I ended finding the source (the drain) and placed a stopper to prevent more flies from coming out of the pipes.

  • Joanna:

    I am house sitting for a friend. He is a relatively clean eprson but gnats have dominated the space for the past few days. We have already taken a bunch of precautionary measures like pouring bleach down the bathroom pipes and putting out a few apple cider vinegar traps. There does seem to be a decrease in the number of flies we spot now but they are still around here and there. We take out the garbage regularly and have no idea where the gnats are coming from.

  • Wine is your best friend:

    I live in Southern California where we get tons of gnats during the summer. I searched tiredlessly to find a solution and ended up finding a winner. The apple cider vinegar trap works but what worked even better for me was using wine, specifically some leftover white zinfandel wine. With the same method as the vinegar trap, the wine trap was able to capture three times as many gnats!!

  • MeganK:

    People. You are doing it all wrong. You are trying to only get rid of the adult flies. To truly get rid of gnats, you need to also get rid of their eggs and larvae. If, for exmaple, all the tiny flies are coming from your plants then you are dealing with fungus gnats. You need to use methods like mosquito bits to get rid of the larvae in the soil. Vinegar traps alone won’t help you.

  • Mjordan:

    How on F do I get rid of these stupid gnats? They are flying around my face and I’ve tried a lot of the methods suggested here.

  • Losing My Mind:

    I tried everything I could think of and the gnats won’t go away. I am pretty sure I am not dealing with fruit flies. I first cleaned up the gutters thinking they were breeding there. Nope. I then dumped a lot of food-grade diatomaceous earth over the garden bed thinking I might be dealing with fungus gnats. Nope again. I now tried using the hanging liquid fly traps. The gnats don’t seem to take a interest in them. What do I do now?

  • Sue:

    I make sure I have something down at the door entryway front door and back..and then I use the solution with apple cider vinegar and so on…AND THEN I TOP IT OFF WITH RAID OF BLACK FLAG FOGGER

  • Rosie:

    Every night put bleach down the drain and clog the drain

  • Robin:

    Tiny, swarm around face, hair & sting

  • Ksowder:

    We have thay exact trash can and we find gnats in it constantly. We bought it to hopefully keep them out. Does not keep them out at all. Just thought I’d put that out there for anyone wanting to purchase it for that purpose. You’re better off with an old school metal trash can you can close tightly.
