What concoction can I make to get rid of trap gnats? Nobody wants to live with pests, especially incredibly disgusting tiny gnats. Therefore, many are looking for various therapies—whether natural, at-home remedies, or the most effective types of spray or foggers (for outdoor infestations)—that will permanently rid their home of gnats.

But, before we get into the eradication methods, it’s critical that you correctly identify the tiny bugger that’s wreaking havoc in your kitchen.

Because there are numerous methods for getting rid of gnats, drain flies, fruit flies, and other pests with wings, you need to be specific. That way, you’ll be able to get rid of the bugs for good.

What concoction can I make to get rid of trap gnats?

If you’ve successfully recognized the pest as a gnat and know where the gnats are coming from, you can try a few natural, at-home cures before resorting to the more complex methods.

Fruit flies, midges, and no-see-ums are common names for gnats found in and around our houses. Whatever you call them, getting rid of gnats might be challenging but not impossible. Here are some old-school approaches to try: 

  1. Wine Trap (DIY)
  2. Cider Vinegar Trap
  3. Fruit Trap With Rotten Fruit
  4. Candle Trap
  5. Bleach Solution, Diluted
  6. Gnat Repellent Spray (Home-made)
  7. Sticky Traps
  8. Flypaper

All you need to know:

Wine can also be used to trap gnats. After all, it’s delicious, aromatic, and sweet—exactly what a flying pest craves. Use a previously expired wine, as outdated wines contain more vinegar than wine. You’ll only need a small amount of wine from the bottle’s bottom.

A few drops of liquid dish soap should be added. This trap works the same way as the apple cider vinegar trap, but it may work better because gnats have a hard time flying back up and out the wine bottle stem.

In contrast to the long-held belief that honey draws more flies than vinegar, this tried-and-true technique has been proven to work.

Dish soap and sugar in a mixing basin with 1/2 cup of warm water and 2 tablespoons of apple cider vinegar. Mix well. Combine all of the ingredients with a fork until the sugar has dissolved.

Wherever gnats are present, place the bowl. While the smell of sugar and vinegar will entice the gnats, soap will snare them after they drink.


Small moscerni feed on fruit (persimmon) rotting.

Yes, the very item that started the gnat infestation could be your best option for getting rid of it. Cover a large bowl with plastic wrap and fasten with a rubber band after adding a few pieces of overripe fruit.

Make a few holes inside the top using a toothpick. Gnats and fruit flies will soon rush to the fruit, infiltrating through the tiny holes—but they won’t know how to get out.

This trap is particularly heinous—death by an open flame and all—but it works. Place a candle in a candlestick, then balance the candlestick in a small pan of water. Try this approach at night to reduce the light streaming in through the windows. Turn off the lights and only light the candle.

The flame will attract the gnats, and one of two horrible things will happen: they will either perish in the fire or fall and drown in the water below.

If you’ve spotted gnats congregating near your sink drains, they could be drain flies (in which case, the other traps we’ve covered here might not be effective).

Bleach is the most effective insecticide for drain flies. Protect your lungs, then dilute one-half cup bleach with one gallon of water and pour it down the afflicted drain.

Fill a spray bottle with dish soap, water, baking soda, and vinegar. For each cup of water, add a few drops of dish soap, a tablespoon of vinegar, and a pinch of baking soda.

This mixture works well as a gnat repellant. They can be sprayed in places where gnats are common, such as near plants, lavatories, and so on.

The sticky traps are available for purchase at retail nurseries and garden centers. Yellow adhesive traps can be cut into smaller squares and adhered to the wooden skewers and flowerpots. Gnats are suffocating on top of them.

The 2-step-trap

Gnats are drawn to wet soil. Thus, they are attracted to houseplants. Spread some honey on some bright yellow index cards to get rid of them. Stick the card into the ground of the gnat’s favorite houseplants after gluing it to a straw or chopstick.

Gnats are drawn to yellow because it is the color of stressed plants, whose defenses against predators are compromised. When the gnats arrive to examine, they will become entangled in the honey.

For generations, the old-fashioned sticky flypaper has been a tried-and-true method of catching and killing flying insects, especially gnats. Hang the sticky paper where gnats are present and wait for them to become trapped in the exposed glue.

In most cases, traditional ribbon flypaper will suffice. If you have gnats swarming your windows, try using window fly traps. Adhere these rectangular transparent plastic sheets to the windowpane and peel away the protective facing to reveal the bug-trapping adhesive.


Gnats can’t truly hurt you, although they can be annoying. Rotting fruit is a regular offender, but it is far from the only one. Dirty dishes, rotting food in garbage bags, and even damp potting soil can attract gnats and drive you insane.

The most excellent news is that there are a few ingenious ways to get rid of gnats in your house that take nothing more than things that you most likely already have in your kitchen cupboards, pantry, and fridge.

The following is a room-by-room explanation of gnat-removal tactics that will assist you in resolving the problem before it worsens.
