what repels no see ums
What repels no-see-ums best are a mix of strong-scented repellents on your skin and smart changes to your environment.
Quick Scoop
No-see-ums (biting midges) are tiny but their bites can be miserably itchy, especially in warm, humid places or near water. The good news: you can make yourself and your yard much less inviting to them with the right products and habits.
What repels no-see-ums from your skin
Most effective “conventional” options
- DEET-based repellents labeled for no-see-ums, sand flies, or biting midges.
- Picaridin lotions or sprays (often 20% concentration, some last up to about 12–14 hours).
- Permethrin on clothing (spray treatment for fabric only, not for bare skin).
Natural or plant-based repellents (usually shorter-lasting, need reapplication)
- Essential oils with strong scents:
- Citronella
- Lemongrass
- Peppermint
- Geranium
- Eucalyptus
- Camphor
- Mint mixes
- These can come as:
- Ready-made “natural” bug sprays
- Roll-on oil blends
- Lotions or balms infused with the oils
Think of it like “smell camouflage”: strong plant scents help confuse how they find you by CO₂ and body odor.
Practical application tips
- Cover all exposed skin, especially ankles, wrists, and neck.
- Reapply natural products frequently (often every 1–2 hours outdoors).
- Avoid heavy perfumes or scented body products that may attract them.
What repels no-see-ums from your space
Environmental changes
No-see-ums thrive where it’s warm, humid, and still. Making your area less comfortable for them is huge.
- Fans and moving air :
- Use box fans or ceiling fans on porches and patios.
- Moving air makes it hard for them to fly and find you.
- Dry out moisture :
* Remove or drain standing water (buckets, plant saucers, clogged gutters, puddles).
* Improve drainage in soggy lawn spots.
* Indoors, use air conditioning or a dehumidifier to cut humidity.
- Screens and barriers :
* Install “no-see-um” mesh screens (tighter weave than regular window screen).
* Use screening on porches and gazebos.
* Close doors quickly and keep windows screened in peak season.
- Light and color choices :
* They are attracted to light and dark clothing.
* Dim unnecessary outdoor lights when relaxing outside.
* Wear light-colored clothing that reflects heat.
Products and ingredients to look for
Here is a simple guide to common ingredients you’ll see on labels:
| Ingredient / Type | Role against no-see-ums | Typical use |
|---|---|---|
| DEET | Strong broad-spectrum repellent, effective vs. no-see-ums when labeled for them. | [9][5]Sprays or lotions on exposed skin. |
| Picaridin | Modern repellent, good protection for several hours; some formulas report up to ~14 hours. | [3][5]Lotions or sprays for skin. |
| Permethrin | Insecticide/repellent on fabric; helps keep no-see-ums from landing and biting through clothes. | [1]Spray on clothing, shoes, gear (not skin). |
| Citronella oil | Strong smell confuses biting insects including no-see-ums. | [7]Candles, torches, topical repellents. |
| Lemongrass, geranium, peppermint oils | Common “natural” blend shown to repel no-see-ums. | [5]Natural sprays, roll-ons, body oils. |
| Camphor, eucalyptus, mint | Strong scents that no-see-ums dislike. | [1]Diffusers, DIY sprays, balms. |
Behavior tricks that help
- Timing your outings :
- No-see-ums are most active at dawn and dusk; limiting exposure then can really reduce bites.
- Clothing choices :
* Wear long sleeves, long pants, socks, and closed shoes.
* Choose tightly woven, light-colored fabrics so they can’t bite through as easily.
- Traps and devices (mixed results, but sometimes helpful)
* CO₂ traps lure and capture no-see-ums over time.
* Some outdoor devices use allethrin or similar actives to create a treated “bubble” of protection.
* These tend to work best as part of a bigger strategy, not alone.
Safety notes
- Follow label directions on any repellent, especially with kids, pets, and pregnant people.
- Essential oils can irritate skin; always dilute and patch-test.
- Keep oils and repellents away from eyes, mouth, and broken skin.
TL;DR
To repel no-see-ums: use a reliable skin repellent (DEET or picaridin, or strong essential-oil blends), run fans and dry out moisture, wear long light- colored clothes, and protect your spaces with fine mesh screens and, if needed, traps or outdoor devices.
