Although they can’t really harm you, gnats are certainly annoying. The mere presence in your house of these pesky insects can leave you feeling twitchy and wondering what brought them inside in the first place. Rotting fruit is a common culprit, but it isn’t the only one. Dirty dishes, trash bags with spoiled food, and even damp potting soil can cause gnats to congregate and drive you crazy. The good news: There are a handful of clever tactics for removing them from your house that require nothing more than ingredients that you probably have in your kitchen cabinets, pantry, and fridge. Here is a room-by-room breakdown of gnat-removal strategies that will help you fix the problem before it gets worse.
Have a few gnats hanging around your fruit basket? Here’s a tried-and-true way to get rid of them. To pull it off, you’ll need apple cider vinegar, sugar, dish soap, water, and a container. Simply mix approximately two tablespoons of vinegar with one liter of water. Add a tablespoon of sugar and a few drops of dish soap, stir it all together, and set the container near the fruit. The insects will be attracted to the scent, then when they make contact with the solution they’ll get stuck in the soap and drown.
The next time you’re sipping a glass of red wine at the dinner table and notice the occasional gnat hovering around, get ready to set out an extra glass. Gnats are attracted to the sugary, fermented beverage, so use it to lure them to their death. Simply pour a small amount of wine into a glass, and add a dash of liquid soap—just be sure you don’t get confused and drink out of the wrong glass! The gnats will fly right in, get stuck, and collect in the alcohol.
Gnats that swarm around the sink or above tub drains are particularly aggravating. Unfortunately, in these instances, apple cider vinegar or wine isn’t always enough to handle the problem. If the gnats are hovering near the surface of the drain, try this trick: Dilute some bleach with water, and then pour it down the drain. One-half cup of bleach to one gallon of water should be enough. (Be sure to wear protective gloves and a mask so you don’t inhale the fumes.) Repeat as needed until you don’t see any gnats.
Sure, rotten fruit attracts gnats, but it’s also something you can use to beat them at their own game. The next time you have a rotten or overripe banana, mash it into a container, such as a small mason jar. Next, put plastic wrap over the top of the jar before puncturing the plastic with a scattering of holes. Gnats will wiggle through the openings to get to the fruit, but the transparent cover will prevent them from flying back out.
If you notice just a gnat or two circling the room, this method is for you: Fill a spray bottle with a mixture of one cup of water, one tablespoon of vinegar, and a few drops of dish soap. The next time you see a gnat flying around, zap it in the air with a spritz. And don’t worry—this solution won’t harm your indoor plants.
