Winter is here – your heater is on full blast, holiday lights are twinkling, and cookies are baking in the oven. Everything feels cozy and festive.
But then, like a scene out of a Hallmark drama gone wrong, a few tiny bugs are suddenly circling your fresh hot cocoa.
Gnats. Somehow these pesky insects don’t care about freezing temperatures outdoors – they’re crashing your holiday vibe like unwanted guests at a family party. They’re just happy to be here.
But where do gnats come from, especially in the winter, when most other pests seem to have disappeared? Believe it or not, gnats can remain active indoors during the winter when given the right conditions.
Let’s take a closer look at what gnats are, what attracts them indoors, and most importantly, how you can get rid of them ASAP. Don’t worry – you don’t have to wait until spring.
What Exactly Are Gnats?

First off, what are gnats? Don’t mistake their small stature for innocence.
Gnats are tiny, flying insects that can vary by type, but the most common ones around homes fall under fungus gnats, fruit flies, and drain flies. These tiny nuisances are often misidentified – while they’re small and buzzing, they’re NOT baby flies or mosquitoes. Gnats are their own type of pest entirely.
These winged pests thrive in warm, moist environments and are often drawn to organic material. While their appearance might be similar, each type of gnat has its own hotspot and preferences. Any standing water, overwatered plants, or leftover food debris in your house could be fueling their numbers.
Why Are Gnats More Common in Winter?

Aren’t bugs supposed to disappear or hibernate during the colder months? Not so fast.
The thing about winter is that while it forces some pests to go dormant, others find refuge indoors where it’s nice and warm. Unfortunately, your cozy house is just as inviting to them as it is to you.
The reasons why are plenty, but a few of the most common include:
- Heating Up Indoors: The warm air indoors can simulate the summer conditions gnats love.
- Humid Air: Humidity from indoor cooking, bathing, or even overwatered houseplants creates the perfect micro-climate for gnats.
- Spoiling Food: Forgot to throw out that fruit salad or left veggies on the counter? Gnats can feast and multiply quickly.
That’s why even in December or January, you may notice gnats thriving – especially around specific problem areas in your home.
If you’ve spotted a crowd of gnats zipping around your home, it usually means they’ve found something to snack on (or lay eggs in).
Gnats need moisture to thrive, which is why damp, organic materials tend to lure them indoors. From overwatered plants (that fiddle-leaf fig of yours might be secretly hosting a gnat family if its soil stays soggy) to standing water (like that around sinks, drains, or pet bowls), they’re great at finding moisture.
Again, rotting food is also a prime target. Overripe bananas on the counter or dirty dishes can become a gnat buffet, as can kitchen drains that are clogged with food residue. Both can easily become a breeding ground for gnats.
How to Get Rid of Gnats

The good news is that clearing out gnats for good doesn’t call for anything drastic – just some strategic moves.
Step 1: Track Down the Source
Gnats don’t just show up for fun – they’re there because they’ve stumbled upon food, water, or shelter. Inspect your plants, trash bins, drains, and any areas where moisture builds up.
Step 2: Eliminate Moisture
Dry out your home wherever possible. Avoid overwatering plants, empty pet water bowls when not in use, and watch out for leaky faucets.
Step 3: Clean Everything
Scrub your drains with a mixture of baking soda and vinegar. Take out the trash often. And yes, hide that fruit until the gnats are gone!
Step 4: Set Traps
Homemade traps can be effective when created and placed strategically. For example, you can fill a jar with apple cider vinegar and add a few drops of dish soap. Then, cover the jar with plastic wrap and poke small holes in the top.
The theory here is that gnats will be attracted to the sweet smell, but won’t be able to escape.
