If you're wondering whether mosquito repellent works on gnats, the short answer is: sometimes—but it depends on the repellent and the type of gnat.
Many mosquito repellents can help reduce gnat activity because some of the same ingredients that deter mosquitoes may also discourage gnats. However, gnats behave differently from mosquitoes and are often attracted to moisture, decaying organic matter, plants, and sweet smells rather than body heat and carbon dioxide alone.
So while mosquito repellent may help, it's not always a complete solution.
In this guide, we'll explain when mosquito repellent works on gnats, when it doesn't, and the best ways to keep these annoying insects away.
Understanding the Difference: Mosquitoes vs. Gnats
Before discussing repellents, it helps to understand how these insects differ.
| Feature | Mosquitoes | Gnats |
|---|---|---|
| Size | Larger | Very small |
| Main Attraction | Body heat & CO₂ | Moisture & organic matter |
| Common Locations | Near water | Plants, soil, fruit, damp areas |
| Biting Behavior | Blood-feeding | Some bite, some don't |
| Repellent Effectiveness | High | Moderate |
Because their behavior differs, products designed specifically for mosquitoes may not always fully address gnat problems.
What Types of Gnats Are Most Common?
Not all gnats are the same.
Fungus Gnats
Often found around:
- Houseplants
- Gardens
- Damp soil
These gnats are primarily attracted to moisture rather than people.
Biting Gnats
Sometimes called:
- No-see-ums
- Sand flies
- Biting midges
These are the gnats most likely to respond to personal insect repellents.
Eye Gnats
These annoying insects often hover around:
- Eyes
- Faces
- Sweat
They can be particularly frustrating during outdoor activities.
How Do Mosquito Repellents Work?
Mosquito repellents work by interfering with insects' ability to locate their targets.
Common active ingredients include:
- Neem oil
- Citronella
- Lemon eucalyptus
- Picaridin
- DEET
- Essential oil blends
These ingredients can mask scents that insects use to locate people. Since some gnats also rely on scent cues, certain repellents may provide partial protection.
Natural Ingredients That May Help Repel Gnats
Many people prefer natural bug sprays for outdoor use. Natural ingredients commonly associated with insect deterrence include: Neem Oil
Neem has been widely used in natural insect-control products.

Peppermint
Its strong scent may help discourage some insects.
Lavender
Frequently used in natural pest-management products.
Why Gnats May Still Bother You After Using Bug Spray?
Many people become frustrated when they use mosquito repellent but still notice gnats.
This happens because gnats are often attracted to:
- Moisture
- Damp soil
- Compost
- Decaying vegetation
- Overripe fruit
- Sweet scents
Even if your bug spray works, environmental attractants may still draw gnats into the area.
Best Ways to Keep Gnats Away Outdoors
For long-term relief, combine bug spray with additional prevention strategies.
Keep Outdoor Areas Dry
Reduce excess moisture where possible.
Remove Decaying Organic Matter
Clean up:
- Fallen fruit
- Leaves
- Plant debris
Use Fans
Gnats are weak flyers. A steady breeze can significantly reduce their activity.
Eliminate Standing Water
Standing water attracts many insects, including mosquitoes.
