No-See-Ums Driving You Crazy? Here’s How to Protect Your Yard

Warm weather brings sunshine, cookouts, and… no-see-ums? These invisible pests, also known as biting midges, are infamous for delivering painful, itchy bites that can ruin your time outdoors. They’re tiny enough to pass through standard window screens, and their favorite hangout spot? Your humid, shaded backyard.

At Evergreen Pest Control, we know firsthand how frustrating no-see-um infestations can be. That’s why we’ve put together this actionable guide to help you identify, manage, and eliminate no-see-ums from your yard.

What Are No-See-Ums?

No-see-ums are tiny, biting flies that belong to the family Ceratopogonidae. Despite their minuscule size (1–3 mm), their bites can cause red, itchy welts that linger for days. They’re most active during dawn and dusk and are drawn to body heat and carbon dioxide—making humans prime targets.

Unlike mosquitoes, no-see-ums can breed in wet soil, damp mulch, and standing water, making your yard a potential hotspot.

1. Eliminate Standing Water and Moisture Zones

The first step in winning the war against no-see-ums is removing their breeding grounds. These insects thrive in moist, swampy areas where they can lay their eggs.

To reduce no-see-um populations:

Empty birdbaths, buckets, and plant saucers regularly
Fix leaky hoses or faucets
Improve yard drainage
Avoid overwatering lawns or gardens

By keeping your yard dry and well-maintained, you cut off their life cycle at the source.

2. Invest in Yard-Wide Pest Control Treatments

For severe infestations, consider professional yard treatments. Evergreen Pest Control offers seasonal misting and barrier treatments designed to kill no-see-ums and prevent their return.

Our eco-friendly treatments target adult insects and larvae while remaining safe for children, pets, and pollinators. Learn more about our mosquito and midge control services designed specifically for small flying pests.

3. Use Outdoor Fans in Sitting Areas

No-see-ums are weak fliers. They struggle to navigate in strong air currents, which is why outdoor fans can act as a natural repellent.

For patios, decks, and outdoor seating areas:

Install ceiling or oscillating fans
Aim air toward your sitting area to deter flight
Combine fans with citronella or eucalyptus candles for extra effect

It’s a simple but effective solution for pest-free lounging.

4. Apply Effective Insect Repellents

When spending time outdoors, protect yourself and your family with insect repellents specifically labeled for no-see-ums. Look for:

DEET (25–30% concentration)
Picaridin (20%)
Oil of lemon eucalyptus for natural alternatives

Always follow label instructions and reapply after swimming or sweating. For babies and toddlers, consider protective clothing instead of chemicals.

5. Create a No-See-Um Barrier with Landscaping

Proper landscaping can make your yard far less inviting to no-see-ums:

Trim dense shrubs and tall grasses regularly
Avoid thick ground cover near patios or doorways
Use gravel or pine bark mulch instead of moisture-retaining types

Add insect-repelling plants like lavender, marigold, and lemongrass to borders and pathways. Not only do they look great, but their scent naturally repels biting insects.

6. Try CO₂ Traps and Bug Zappers

Some homeowners find success using CO₂-emitting traps, which lure no-see-ums using the same gas humans exhale. These traps attract and kill the insects before they can bite.

For best results:

Place traps near problem areas but away from sitting zones
Clean them out regularly
Use traps in combination with other tactics for maximum protection

While traditional bug zappers are less effective on no-see-ums due to their size, newer models that emit UV and CO₂ work better.

7. Install Fine Mesh Screens and Netting

No-see-ums can squeeze through standard window screens and screen doors. Upgrade to ultra-fine mesh screening (16-mesh or finer) for:

Porch enclosures
Gazebos
Windows and doors

For added protection while camping or lounging outdoors, use mosquito netting around beds, hammocks, or tents.

Protecting Pets and Kids from No-See-Ums

Children and pets are especially vulnerable to no-see-um bites. Here’s how to keep them safe:

Dress kids in light, long-sleeved clothing
Use pet-safe insect repellents recommended by your vet
Avoid letting pets nap in shaded, damp areas

If bites do occur, use hydrocortisone cream or oral antihistamines to reduce itching and inflammation.
