What Causes Gnats to be in Your House?

Causes

Typically, they will enter your house from the outdoors through walls, windows, doors, or even little cracks or holes in your foundation. Since gnats feel most at home in a warm, moist environment,  they often search out to infest trash cans, rotting fruit, sugar, overwatered soil, drains and more. Make sure to keep an eye out for anything you may have left out in the open that could attract them. All it takes for them to come back is one overripe banana, and they’ll be making themselves at home again!

Prevention

The best thing to do is keep your kitchen clean, as well as the whole home. This will make it less likely for you to attract gnats. Make sure to store your food in sealed containers and throw out any overly ripe fruit. It’s also best if you have a tightly covered trash can and clean out your drains and garbage disposal regularly. If you see them flying around most frequently around your plants, try letting your plants dry out in between watering. This will prevent the critters from laying eggs.

Neem Oil

Neem oil is an organic insecticide that is made from the seeds of neem trees. You can find such oil at most places that sell plants. However, when buying make sure to see if you are getting a concentrate, which you will need to dilute yourself or if it’s already in a pre-diluted spray bottle. If you have fungus gnats soak the top 5 to 10 cm of the plant’s soil with the oil about once a week for a month or two.

Wine

This trick is similar to the apple cider vinegar one. You can just use wine instead of the vinegar, or you can leave a nearly empty wine bottle open on its own. Gnats will crawl inside as they are attracted to the smell but won’t be able to get back out.

Fruit Trap

On the same principle as the wine and vinegar, you can also use fruit. Leave rotting fruit in a jar or bowl, cover it with some plastic wrap and secure it. Poke some hole in the wrap and the gnats will rush to it and get trapped in the process.
