We're all guilty of it: at least once in all of our lives, we've confused fruit flies with gnats, or vice versa.
How can you not be?
They're both teeny-tiny pests that you wish would just leave your home once they manage to creep inside.
However, there are a number of striking differences between the two, and it will be beneficial for you to understand which is which.
Keep reading to be able to recognize the differences between the two.
Gnats or Fruit Flies in the Kitchen?
Are you sure you've got the right insect in mind?
Check out the sections below for more in-depth characteristics.
Fruit Flies Everywhere, or is it Gnats?
Both fruit flies and gnats seem to invade suddenly, but through different channels.
Fruit flies usually ride into your home as eggs embedded on the surfaces of fruit and vegetables, whereas gnats generally enter the home in the soils of potted plants.
Gnats like to hover in groups, whereas fruit flies only congregate together when lots of food sources are present (for example: a bowl of fruit sitting on the kitchen counter).
Are There Fruit Flies in Your Drains (or Something Else)?
Oftentimes, you'll spot a few fruit flies hovering around your kitchen, stopping every once in a while to take a slurp of a fruit's juices.
While this is gross, hear us when we say this: that may not be the only type of fly in your kitchen.
It's easy to assume that fruit flies will fly right into the drain of your sink, maybe to take a sip of water after they've fed. And yet, this isn't necessarily the case.
There's another type of fly that lives primarily in wet drains called the drain fly, and to the casual observer, these two species of insects can look very similar.
How to tell drains flies apart from fruit flies...
Fruit flies have very sleek bodies while drain flies, on the other hand, have wings that spread out like a moth's and a huge tuft of fur on their heads.
Drain flies tend to feed on stuff that is fermenting in your drain.
Here's a quick video on a mechanic actually fixing a drain fly issue...
Fruit Fly Infestation or Gnat Infestation Throughout Your House?
Kitchens aren't the only place that fruit flies can live, but it's the most likely spot.
If you're seeing swarms of small flies in a room other than the kitchen, it's probably a hoard of gnats.
Well, fruit flies love fermented food like decaying fruits, beer, wine, and vinegar.
They're usually not going to venture too far from the source of all of that, which is primarily found in the kitchen.
Gnats on the other hand...
...have a much more varied diet.
While they do love the taste of fruits and vegetables, they're also attracted to mold, plant leaves, and even blood. These items are not limited to the kitchen, so if you're seeing a swarm elsewhere, look out, you've probably got gnats.

Is it Their Fruit Fly Eggs?
This is the primary way that fruit flies get into your home in the first place.
Female fruit flies lay eggs in fruit that's just on the cusp of turning, when ripeness is at its peak. This happens all the time in grocery stores and especially in outdoor markets, where pest control is nearly impossible.
What Causes Gnats in Your Home?
All right, we've had a crash course on fruit flies, and little ways you can tell them apart from gnats.
But what about gnat characteristics on their own?
Where Do Gnats Come From?
Usually, they'll roll into the walls of your home in the soils of a potted plant you pick up from a gardening store.
However, this isn't the only way.
Because some types of gnats are drawn to mold and slime, they can reach your home via drain pipes and eventually, make their way inside through the drains in your sinks and bathtubs.
Also, never underestimate the small cracks in the structure of your home. It may not even be apparent that you have tiny openings, but little bugs and pests will always use that as an entry point to the warmth of your home if it's available to them.

What Attracts Gnats?
A warm home is always an attractive place for gnats to take up residence. However, these insects are also in favor of damp plant soil, moisture-soaked crevices, stagnant pools of water, and sometimes, blood.
Because there are several different types of gnats, it can be difficult to generalize what exactly each species finds alluring.
However, it's a solid bet that if you have moisture or standing water of any kind present over time in your home, the gnats will make a move.
Gnat Infestation: Should I Be Worried?
If you spot a swarm of gnats in your home, there are simple ways of eliminating them. It actually might be beneficial to you, in a way; without the side effect of a gnat infestation, many homeowners wouldn't realize that they have a moisture or mold problem in their walls.
How to Take Each of Them Out
If you know how to identify a fruit fly vs. a gnat, you can take the appropriate steps toward evicting them from your home.
Let's get into some methods for elimination...
How to Kill Fruit Flies: Home Remedies
There are a few different products on the market to get the fruit flies out of your way, but more often than not, it can be more cost-effective to go DIY and use some stuff you already have lying around.
One trick to catch fruit flies is to simply leave a bottle of red wine out, uncorked, with a bit of wine in the bottom. The fruit flies will dive right down into the nose of the bottle to get to the wine and be trapped.
Another quick way to grab the fruit flies is to chop up some banana slices and place them in a jar or a glass. Cover the opening with a piece of plastic wrap, and puncture a few holes in the top of it. The fruit flies will be lured in by the scent of the banana, and not be able to find the top holes to fly out of the trap.
While it can be daunting to try and eliminate every last egg, larva, pupa, and adult fruit fly that's moved into your home, there are things that you can do to make your kitchen less hospitable to these pests.
- thoroughly wash your produce before eating
- seal fruits and vegetables in plastic, or keep in the fridge
- place some fruit fly traps around the kitchen to catch them in action

How to Kill Gnats: Home Remedies
In much the same fashion as getting rid of fruit flies, taking the gnats out of your home will probably involve a quick homemade remedy out of staples you more than likely already have.
Gnats are generally attracted to animal waste, sewage, mold, and moisture. Needless to say, these aren't the kinds of things you're going to want to put in a jar on your countertop. To catch gnats, you can use fruit or vegetables, just like you would for fruit flies. While gnats don't go for these types of baits naturally, they'll fly right toward them if they're offered out in the open.
