Nothing ruins a quiet evening on the porch faster than a cloud of tiny gnats swarming your face, eyes, or drink. Here in Eastern North Carolina, warm weather and humidity create perfect conditions for several different kinds of “gnats” – from fungus gnats around houseplants to biting gnats and no-see-ums around water and damp soil.
D & D Pest Control Co. helps homeowners and businesses across Eastern NC figure out what kind of gnats they’re dealing with, where they’re coming from, and how to bring the population back under control.
What Exactly Are Gnats?
The word “gnat” doesn’t refer to just one insect. It’s a common name for several tiny fly species in the order Diptera. These small flies are typically between 1/16 and 1/8 inch long, with slender bodies, long legs, and long antennae.
In and around homes, the most common culprits include:
- Fungus gnats – non-biting gnats often found in and around houseplants and damp potting soil. Their larvae feed on fungi and decaying organic matter in the soil and can damage delicate roots when populations are high.
- Biting gnats / no-see-ums (biting midges) – tiny flies whose bites can leave painful, itchy welts. They are often active around dawn, dusk, and on cloudy days and can be so small they sometimes pass through standard window screens.
- Other small flies – people sometimes call fruit flies, drain flies, and non-biting midges “gnats” as well, since all are small flying insects that hover in swarms or around food, drains, and lights.
The key to solving a gnat problem is correct identification and then removing the moisture and organic material they use to breed.
Why You Have Gnats in Your Home or Yard
Gnats are strongly attracted to moisture and organic matter. If they’re hanging around, there is almost always a breeding source nearby.
1. Fungus Gnats Around Houseplants
Indoors, the most common gnat issue is fungus gnats. They thrive in:
- Overwatered houseplants
- Pots with poor drainage and constantly wet saucers
- Potting mixes rich in peat, compost, or other organic matter
NC State Extension notes that the key to solving fungus gnat problems is to find and eliminate excess moisture in the potting soil. Allowing the top layer of soil to dry between waterings quickly reduces their numbers.
2. Gnats in Kitchens, Baths & Drains
Some small flies that homeowners call “gnats” actually breed in:
- Sink and floor drains
- Garbage disposals and slimy organic build-up
- Trash cans, recycling bins, and mop buckets
- Rotting fruit or forgotten kitchen scraps
These flies are often controlled with better sanitation, drain cleaning, and trash management, plus targeted treatments when needed.
3. Biting Gnats & No-See-Ums Outdoors
Outside, especially near water, marshes, or saturated soil, you may run into biting midges, often called no-see-ums. These tiny gnats can:
- Swarm around decks, patios, and porches
- Bite ankles, arms, neck, and face
- Leave small, very itchy welts that can be worse than mosquito bites for some people
They typically breed in wet soil, mud, and decaying plant material in low, damp areas – so moisture management and habitat reduction are critical.
Are Gnats Dangerous?
Most gnats are more of a nuisance than a serious health threat, but that doesn’t mean they should be ignored.
- Fungus gnats – do not bite people. Heavy infestations, however, can damage young plant roots and stunt houseplants or seedlings.
- Biting gnats / no-see-ums – their bites can be extremely itchy and uncomfortable, and scratching can lead to secondary infection. Some species transmit diseases to animals, though they’re not generally considered major disease vectors for humans in residential settings.
- Other small flies – can transfer bacteria from drains or decaying organic matter onto surfaces or food, contributing to sanitation issues.
Even when they’re “only” a nuisance, gnats can make it hard to enjoy your home, yard, or porch – and that’s when it’s time to take action.
How to Reduce Gnats on Your Own
Before and during professional treatment, you can take simple steps to cut down on gnat breeding sites.
For Fungus Gnats & Indoor Gnats
- Let plant soil dry out between waterings. Fungus gnats lay eggs in constantly moist soil; reducing watering frequency is one of the fastest ways to control them.
- Empty plant saucers. Don’t let water sit in saucers under pots for days at a time.
- Improve drainage. Repot into well-draining mixes and containers with proper drainage holes.
- Clean drains and garbage disposals. Use a brush and labeled drain cleaners to remove organic build-up where drain flies and gnats can develop.
- Dispose of overripe fruit and food waste promptly. Keep trash cans covered and liners changed regularly.
For Outdoor Gnats & No-See-Ums
- Eliminate standing water. Dump water from buckets, toys, plant saucers, birdbaths (or refresh frequently), and low-lying containers.
- Improve yard drainage. Fill low spots, unclog gutters, and correct grading issues where water collects.
- Manage organic debris. Rake up decaying leaves, grass clippings, and rotting mulch in areas where gnats are dense.
- Use screens & fans. Fine-mesh screens and outdoor fans on porches and patios can make it harder for gnats and no-see-ums to zero in on you.
These steps won’t eliminate every gnat, but they reduce the breeding pressure and make professional treatments more effective and longer-lasting.
Professional Gnat Control from D & D Pest Control Co.
Gnats can be tricky. You might swat dozens and still see swarms the next evening because the real problem is hidden in soil, drains, or a damp corner of the yard.
D & D Pest Control Co. uses a systematic approach to identify and control gnat problems across Eastern North Carolina:
1. Inspection & Identification
- We determine what type of gnat or small fly you’re dealing with (fungus gnats, no-see-ums, drain flies, fruit flies, etc.).
- We locate critical breeding sites: overwatered plants, damp organic debris, drains, low wet areas, or nearby water features.
- We evaluate structural conditions: crawlspace moisture, yard drainage, and vegetation around your foundation.
2. Source Reduction & Recommendations
- We provide clear recommendations on watering practices, drainage corrections, and sanitation improvements.
- For indoor issues, we may suggest adjustments to plant care, drain cleaning, or trash management.
- Outdoors, we focus on reducing moist breeding sites and improving air flow around problem areas.
3. Targeted Treatments
Depending on the gnat species and situation, our treatment plan may include:
- Residual treatments in key outdoor resting areas to knock down adult gnats and small flies.
- Larval or microbial products in specific standing-water sites that cannot be drained, where allowed and appropriate.
- Crack, crevice, and drain treatments in and around structures, following label directions and North Carolina regulations.
- Integration with our mosquito and fly control services where insects overlap.
4. Ongoing Monitoring & Seasonal Service
Because gnats are highly seasonal and moisture-dependent, we can incorporate gnat control into your regular pest control service or set up seasonal treatments when gnats and no-see-ums are at their worst.
Frequently Asked Questions About Gnats
Do all gnats bite?
No. Most gnats people see on houseplants or hovering over potting soil are fungus gnats, which do not bite. The painful bites usually come from biting midges (no-see-ums) and similar small flies, not from fungus gnats.
Why do gnats hover around my face?
Many gnats are attracted to the carbon dioxide and moisture from your breath, as well as lotions and fragrances. That’s why they often hover near faces, eyes, and ears on warm, humid days.
Will store-bought sprays get rid of gnats?
Aerosol sprays may kill some flying gnats you see, but they rarely address the root cause: breeding sites in soil, drains, or moist debris. Without source reduction and targeted treatments, the problem usually returns quickly.
How long does it take to see a difference after treatment?
For fungus gnats and indoor gnats, you can often see improvement within a week or two once watering and moisture issues are corrected and targeted treatments are applied. Outdoor biting gnats may take longer, depending on weather, site conditions, and nearby water sources.
Are gnat treatments safe for my family and pets?
When applied by licensed professionals following label directions, our gnat-control treatments are designed to be both effective and responsible. We’ll explain what to expect, where we’ll treat, and whether any short-term re-entry guidelines apply to treated areas.
Can gnats come from my crawlspace or moisture problems?
Yes. Damp crawlspaces, standing water under a home, and moldy or wet organic material near the foundation can all contribute to gnat and small-fly activity. That’s why we also offer crawlspace moisture evaluations and solutions as part of our overall pest-control strategy.
