There are multiple ways to get rid of your gnat problem, from traps to professional help. If you have a severe gnat infestation, it may take more than one of these methods to eradicate the pests.
1. Make a DIY Gnat Trap
Trying to figure out how to catch gnats? The most popular option is a vinegar trap, which is simple and cost-effective to create. Simply place a few tablespoons of apple cider vinegar or white vinegar, a few drops of dish soap, and a tablespoon of sugar in a bowl and stir. Set your bowl in an area where gnats are prevalent, such as your kitchen or bathroom. The sugar and vinegar combination will attract gnats, and the dish soap traps the gnats and eventually causes them to drown.
If you don’t have vinegar on hand, a combination of red wine and dish soap can create a similar gnat trap. If your gnat infestation is particularly intense, you may want to set out a few bowls of this wine trap mixture around the house.
Finally, a fruit trap can prove effective. Homeowners can cover a jar of overripe fruit with plastic wrap and poke small holes into the wrap’s surface. The gnats will smell a food source and enter the jar, becoming trapped.
2. Use a Spray
If you have a smaller pest problem, a simple spray bottle of one tablespoon of vinegar and a small amount of dish soap may be enough to treat your issue. If gnats are hovering around houseplants or crawling in your potting soil, the issue is likely due to overwatering. To treat this type of gnats, spray a gentle insecticide, such as neem oil or dish soap diluted in warm water, onto the plant. If you use dish soap, you’ll need to carefully wash the solution off after two hours.
3. Bleach Your Drains
If you notice gnats around your kitchen sink or bathtub, pour a cup of diluted bleach down the drain to kill the gnats. Be sure to pour the cup of bleach down each drain or garbage disposal very slowly until there are no more gnats in your line of sight.
4. Make a Candle Trap
Place a candle in a candlestick and fill the holder partially with water. Light the candle and turn off the lights. The gnats will flock to the flame and be burned or will fall into the water and drown. Obviously, this trap is less convenient than a wine or vinegar trap, and you’ll need to remember to blow out the candle before falling asleep.
5. Buy a Glue Trap
Glue traps, or sticky traps, are strips of paper or tape with an adhesive coating that traps gnats. You can set these traps anywhere in your home that sees gnat activity. The traps will need to be replaced often and may have limited effectiveness for large infestations.
6. Install an Electric Insect Killer
You can purchase an electric insect killer, or bug zapper, to install on your porch or patio. These products kill gnats with an electric charge when they fly into the device. Bug zappers are an excellent way to deter biting gnats in your yard but will not fully eliminate their population.
7. Hire a Professional Pest Control Company for Gnat Extermination
If you have a lingering gnat infestation, a professional pest control company can help address it. The best companies have expertise in treating gnat larvae and adult gnats and will create a customized treatment plan for your home at a reasonable cost for pest control.
