What Causes Gnat In The House

Let's start with the basics, shall we? Gnats are those teeny-tiny drain flies or fruit flies, that can range from annoying to downright infuriating. They're like uninvited party crashers, but not the fun kind. Gnats come in various shapes and sizes, but they all have one thing in common: they're experts at getting on your nerves.

As mosquito control experts, at Critter Stop we have prepared an article that we hope be useful to all our readers who may be dealing with Gnat problems. Let's start this journey right away!

Overview of Gnats

Gnats, those pint-sized pests, are like the unwelcome guests at a party that just won't leave. They come in various shapes and sizes, but they all have one thing in common: they're experts at getting under your skin.

Gnats are a diverse bunch, each with its own quirky preferences. Some like to hang around your beloved houseplants, while others set up camp in your kitchen or bathroom. But enough with the introductions; let's uncover the mystery of why they've decided to invade your space in the first place.

Now, let's delve into the intriguing world of gnats and discover why they've chosen your home as their buzzing playground, what causes gnats in the house, where do gnats come from in the house, and how to get rid of gnats.

What Attracts Gnats In The House

So why are gnats in the house? When we have provided mosquito Control services, we have found that gnats can be attracted to various factors in your house. Here are the main culprits that draw gnats indoors:


Ah, moisture – gnats' best friend forever. If your home has any damp, cozy corners, gnats will find them and make themselves at home. These critters are moisture magnets, and they adore laying their eggs in moist soil. Once those eggs hatch, you've got a full-blown gnat party on your hands.

Accumulation of Food Waste

Ever left a few more rotten fruit or peels lying around or neglected the dirty dishes for a day or two? Well, fungus gnats in the house love that stuff! They're like mini garbage disposals, happily feasting on anything edible they can find.

Standing Water

Gnats can turn a drop of water into a hotspot. Puddles in your houseplants' saucers, a neglected sink, or even a forgotten wet cloth can become the perfect gnat breeding ground. So, if you've got stagnant water hanging around, consider it an open invitation for these tiny troublemakers.

Standing Water
Standing water is one of the breeding sites for Gnats.

Overwatered Houseplants

While you're showering your houseplants with love and water, gnats might be showering them with attention. Overwatering your green friends can create a paradise for gnats in the soil. They'll lay their eggs there, and before you know it, your peaceful plant corner becomes a buzzing gnat haven.

Ripe Fruits and Veggies

Gnats have a refined taste for the finer things in life, which includes ripe fruits and veggies. If you leave a fruit bowl for them out on the counter for too long, you're practically setting up a gnat buffet. These little pests can't resist the allure of a juicy and sugar-overripe piece of fruit.

Preventing Gnats in the Home

As mosquito control experts, preparing plans to prevent Gnats from getting into the home is part of our work. Think of this as your gnat moat, a protective barrier against these tiny invaders. Here's how to do it:

Well-Draining Pots: Ensure your houseplants are in pots with good drainage. This helps prevent water from accumulating in the soil, which gnats find irresistible for laying their eggs.

Empty Saucers: Always empty excess water from saucers under your potted plants. Gnats can't throw a pool party if there's no water to party in!

Soil Management: Keep the soil in your houseplants slightly drier. Gnats thrive in moist environments, so maintaining drier soil makes your plants less inviting for these pesky insects.

Properly Sealing Food Waste: No Gourmet Buffet

Inside the kitchen, gnats are always on the lookout for a feast. Here's how to deny them:

Airtight Containers: Seal your food waste properly in airtight containers. This prevents gnats from accessing your kitchen scraps and turning them into a gourmet buffet.

Prompt Disposal: Dispose of food waste promptly. Don't leave it sitting around in open bottles, bins, or on the counter where gnats can easily discover it.

Cleaning and Disinfecting: Party-Poopers Beware

Gnats love a dirty, cluttered environment. Keep them at bay with these cleaning tips:

Regular Cleaning: Make regular cleaning and disinfecting a habit. Pay special attention to areas where gnats are more likely to congregate, like your kitchen and bathroom.

Declutter: Reduce clutter in your living spaces. Gnats love hiding in piles of stuff, so by keeping things organized, you'll discourage them from settling in.

Repair Leaks and Fix Moisture Issues

Gnats are moisture magnets. Here's how to dry up their favorite hangouts:

Fix Leaks: Promptly repair any leaking pipes sink drains or faucets in your home. This eliminates a source of standing water that gnats adore.

Improve Ventilation: Ensure your home is well-ventilated to reduce humidity levels. Proper airflow helps deter gnats from making themselves at home.

Cover Ripening Fruits and Veggies

Gnats have a keen sense of smell when it comes to ripe produce. Foil their plans by covering your fruits and veggies:

Use Covers: Cover ripening fruits and vegetables on your kitchen counter with mesh, plastic wrap or food nets. This prevents gnats from detecting the tempting scents.

Use Screens and Seal Gaps: Prevent gnats from sneaking in through open windows and doors:

Window Screens: Install window screens to keep gnats and other pests out while allowing fresh air in.

Seal Gaps: Check for gaps or cracks around doors and windows. Seal them to deny gnats an easy entry point.

Natural Gnat Repellents

Add some charm to your home while repelling gnats with these natural methods:

Citronella Candles: Place citronella candles strategically around your living spaces. Gnats find the scent unpleasant and will steer clear.

Citronella Candles
This type of candles are a natural repellent.

Vinegar Traps: Set up vinegar traps by placing dishes with apple cider vinegar and a few drops of dish soap near gnat hotspots. The vinegar attracts them, while the soap traps them.

Basil Plants: Keep basil plants indoors. Gnats find the scent of basil unappealing, and it adds a touch of greenery to your decor.

With these preventive measures, you'll create an environment that's far less welcoming to
gnats in the house infestation, ensuring your home remains a gnat-free zone.

Controlling Gnats in the Home

When gnats refuse to take the hint, you can bring out the big guns - chemical control. Here's what you need to know:

Gnat Sprays:

There are insect sprays specifically designed to target and kill gnats only. These sprays often contain chemicals that are effective at killing gnats on contact. Be sure to read and follow the instructions carefully to ensure both safety and effectiveness.

Gnat Traps:

Gnat traps are a less invasive option. They typically use sweet or fruity baits to attract gnats, trapping them on sticky surfaces. These traps are available in various designs, from discreet to decorative.

Foggers and Fumigation:

In extreme cases, foggers and fumigation can be used to eliminate gnats. However, these methods are more invasive and may require temporary evacuation. Professional pest control services can safely perform such treatments.

Remember, while chemical control can be effective, it's essential to use these products with caution, especially if you have children or pets in the house. Ensure proper ventilation after using chemical sprays or foggers, and always store them safely out of reach.

Biological Control: Nature's Bouncers

Ever heard of the saying, "Fight fire with fire"? Well, in the gnat world, you can fight gnats with other critters. Here's how biological control works:

Beneficial Nematodes: These microscopic organisms are your allies in the battle against gnats. They seek out and parasitize gnat larvae, effectively reducing the gnat population in your soil. You can purchase beneficial nematodes and introduce them to your potted plants.

Predator Mites: Predator mites are like the bouncers at the gnat infestation nightclub, keeping the party in check. They feed on gnat eggs and larvae, preventing them from growing into adults. You can also release predator mites in your garden or indoor plant pots to help control gnat infestations.

Biological control methods are eco-friendly and can be an effective long-term solution to gnat problems. However, they may take some time to yield noticeable results, so patience is key when using these natural predators.

Natural Control: Eco-Friendly Tactics

If you're more of a peace-loving, eco-conscious homeowner, consider natural methods. Here's how to do it:

Vinegar Traps: Gnats are drawn to the scent of vinegar. Create a simple vinegar trap, by placing a dish with apple cider vinegar and a few drops of dish soap near gnat hotspots. The gnats will be lured in by the smell, but the soap will trap them.

Essential Oils: Some essential oils, like eucalyptus or lavender, can act as natural gnat repellents. Dilute a few drops of these oils in water and use it as a spray or place soaked cotton balls strategically around your home.

Carnivorous Plants: Consider adding carnivorous plants like sundews or pitcher plants to your indoor garden. These botanical bug-eaters will gladly help themselves to a gnat snack.

Improved Ventilation: Sometimes, all it takes is better airflow. Keep windows and doors open to encourage ventilation, and use fans to disrupt the calm air that gnats love.

Reducing Organic Material: Gnats thrive on decaying organic matter. Compost your kitchen scraps promptly and dispose of any rotting fruit or vegetables in sealed containers to deprive them of a food source.

By implementing these eco-friendly tactics, you can manage gnat issues effectively while minimizing harm to the environment.


In summary, gnats in the house are like the nosy neighbors of the insect world. They're drawn to moisture, food waste, and standing water, and they won't hesitate to make themselves at home if you give them the chance.

Tips for Preventing and Controlling Gnats in the Home

However, with a little vigilance, cleanliness, and some effective preventive and control strategies, you can bid these uninvited guests a not-so-fond farewell. So, go ahead, show those gnats who's boss, and reclaim your gnat-free sanctuary. With the right approach, you can enjoy your home without the pesky presence of these tiny winged intruders.

I’d give a 10 star review if I could! We had a great experience with Critter Stop. Everyone I dealt was friendly, professional, and reassuring. Phillip was very helpful and knowledgeable about the work he was doing. He walked me around the entire house to make sure I saw and understood the services he provided. He was also really nice and answered all my questions — he is exactly the type of person that should be interacting with customers.I love the fact that they will come back for up to 1 year after installation if any problems occur — this shows me they stand behind their work.The owner was great too, he personally came to my house and walked me through their offering. I recommend critter stop to anyone and everyone!

Critter Stop is a fantastic business! Everyone involved is extremely professional and very easy to communicate with. Chisam, the owner, did a great job of explaining the process to get the squirrels out of my attic during the initial free estimate. The exclusion crew who did all of the initial work was fabulous. The crew consisted of Phillip, Nick and Corey who arrived promptly when they said they would. They are happy, positive employees. Everyone is very polite and patient in explaining their work and answering questions. They came back several times to check the traps and finish it off with the fogging. Lester was very good about following up to schedule each trap check with me, and the office staff who took care of the billing was very efficient. Critter Stop is a well run company with honest, trustworthy employees! Thank you to all of you who worked hard to make my attic critter free and for the peace of mind that you guarantee your work. Great to know I can call them if for some reason a squirrel figures out a way to get back in!
