How To Get Rid Of No See Ums In Yard Naturally: Your Guide

Can you get rid of no-see-ums in your yard naturally? Yes, you can effectively manage and reduce no-see-ums in your yard using natural methods.

No-see-ums, also known as biting midges or sand flies, are tiny, pesky insects that can turn your outdoor enjoyment into an itchy nightmare. Their bites are small but pack a punch, causing considerable discomfort. If you’re asking, “What is a no-see-um?” they are tiny, biting flies belonging to the Ceratopogonidae family. Unlike mosquitoes, they are so small they can often pass through standard window screens, making them a nuisance both indoors and out. They are most active at dawn and dusk, but can also be a problem on overcast days. Dealing with these biting gnats requires a multi-pronged approach, focusing on elimination, prevention, and relief. This guide will walk you through how to get rid of no-see-ums in your yard naturally, offering practical solutions for controlling biting midges and preventing gnats in your yard.

Identifying the Culprits: What Are No-See-Ums?

Before we dive into solutions, it’s helpful to know what we’re up against. No-see-ums are not a single species but rather a group of small biting flies. Their common names reflect their size and behavior:

Size: They are typically 1-3 millimeters long, making them barely visible to the naked eye.
Bite: Unlike mosquitoes, both male and female no-see-ums feed on blood. Their bites are sharp and can cause itchy welts that may last for days.
Habitat: They thrive in moist environments, often near standing water, marshes, swamps, and even damp soil. Their larvae develop in these wet areas.
Activity: They are most active during warmer months, particularly during dawn and dusk. However, they can also be active on cloudy, humid days.

Life Cycle of No-See-Ums

Fathoming their life cycle is key to effective midge control. No-see-ums have four life stages: egg, larva, pupa, and adult.

Eggs: Females lay eggs in damp soil, decaying organic matter, or muddy areas.
Larva: The larvae are aquatic or semi-aquatic, living in moist environments. They feed on organic matter and can survive in various damp conditions.
Pupa: The larvae transform into pupae in moist soil or mud.
Adult: The adult flies emerge from the pupal stage and begin to feed and reproduce, starting the cycle anew.

This understanding highlights why targeting their breeding grounds is so crucial for sand fly prevention.

Natural Strategies for No-See-Um Control

The goal is to create an environment that is inhospitable to no-see-ums while protecting yourself and your family from their bites. Here are effective natural methods for eliminating biting insects like no-see-ums.

1. Eliminating Breeding Grounds: The Foundation of Prevention

This is the most critical step in preventing gnats in yard. No-see-ums need moisture to breed.

Removing Standing Water

Empty Containers: Regularly check and empty anything that can collect water, such as flower pot saucers, old tires, buckets, bird baths, and clogged gutters.
Repair Leaks: Fix leaky outdoor faucets and hoses that create puddles.
Proper Drainage: Ensure your yard has good drainage. Waterlogged areas are prime breeding spots. Consider French drains or grading if you have persistent damp patches.
Manage Ponds and Water Features: If you have decorative ponds, ensure they have moving water (like a small waterfall or aerator) to prevent stagnant conditions. Mosquitoes and no-see-ums prefer still water.

Managing Organic Debris

Clear Leaf Litter and Debris: Damp, decaying organic matter can also be a breeding ground. Keep your yard tidy by raking leaves, clearing away grass clippings, and removing rotting wood.
Compost Wisely: While composting is great, ensure your compost pile is not overly wet and is turned regularly to prevent it from becoming a no-see-um haven.

2. Natural Yard Treatments and Repellents

Once you’ve addressed their breeding sites, you can employ natural repellents and treatments to deter adult no-see-ums.

Essential Oils as Natural Repellents

Certain essential oils have strong scents that repel biting insects. These can be used in various ways around your yard.

Citronella Oil: A classic insect repellent, citronella is effective against many flying insects, including no-see-ums.
Peppermint Oil: Its strong scent is highly unappealing to biting gnats.
Lemon Eucalyptus Oil: This oil contains PMD (p-menthane-3,8-diol), a compound recognized by the CDC as an effective natural insect repellent.
Lavender Oil: Known for its pleasant scent to humans, it’s a deterrent for many insects.
Tea Tree Oil: Possesses natural insecticidal properties.
Geraniol: Found in geraniums, this oil is a potent repellent.

How to Use Essential Oils:

DIY Yard Spray for No See Ums: Mix 10-20 drops of your chosen essential oil(s) with water and a tablespoon of mild liquid soap (like castile soap) in a spray bottle. The soap helps the oil emulsify in the water. Spray this mixture around your patio, doorways, windows, and in areas where you spend time outdoors. Reapply every few days, especially after rain.
Diffusion: Place cotton balls soaked in essential oils around your patio or garden seating areas. You can also use a small, battery-operated diffuser outdoors.
Planting Repellent Herbs: Grow herbs like citronella grass, basil, mint, rosemary, and lavender in pots around your outdoor living spaces. Their natural scent can help keep no-see-ums at bay.

Beneficial Insects and Plants

Attracting natural predators and planting repellent flora can contribute to controlling biting midges.

Attract Dragonflies and Damselflies: These insects are voracious predators of flying insects, including no-see-ums and mosquitoes. Encourage them by adding a water source like a pond with moving water and planting native vegetation around it.
Plant Repellent Plants: Beyond the herbs mentioned above, consider planting marigolds, catnip, and chrysanthemums. These plants contain pyrethrin, a natural insecticide, or have scents that deter insects.

Garlic Spray

Garlic is a natural deterrent for many pests.

How to Make Garlic Spray: Blend a whole bulb of garlic with a quart of water. Let it sit for 24 hours, then strain out the solids. Add a tablespoon of liquid soap and spray it around your yard. The strong smell is off-putting to no-see-ums.

Neem Oil

Neem oil is derived from the neem tree and has insecticidal and repellent properties.

How to Use Neem Oil: Mix according to the product label instructions (usually a few tablespoons per gallon of water with a little soap) and spray on foliage and around your yard. It disrupts the life cycle of insects. Be mindful of its potency and avoid spraying during peak pollinator activity.

3. Physical Barriers and Environmental Modifications

Creating physical barriers and altering your yard’s environment can significantly reduce your exposure to no-see-ums.

Fans for Outdoor Areas

The Power of Airflow: No-see-ums are weak fliers. Placing oscillating fans on your patio or deck can create enough airflow to keep them away from your immediate space. This is a simple yet highly effective method for sand fly prevention when you’re trying to relax outdoors.

Outdoor Screens and Netting

Screened Porches and Gazebos: If you have a porch or patio, consider screening it in. Ensure the mesh is fine enough to block tiny insects.
Mosquito Nets: For seating areas, you can hang mosquito netting to create a protected zone.

Lighting Choices

Minimize Attractants: No-see-ums, like many insects, are attracted to light. While they are less strongly attracted than mosquitoes, minimizing unnecessary outdoor lighting, especially during peak hours, can help.
Consider Yellow “Bug Lights”: These lights emit a different spectrum that is less attractive to many insects.

4. Yard Spray for No See Ums: Natural Options

When considering a yard spray for no see ums, natural options are preferred for safety and environmental impact.

Diatomaceous Earth (Food Grade)

What it is: Diatomaceous earth (DE) is a powder made from fossilized aquatic organisms. It has sharp edges that dehydrate and kill insects that crawl over it.
How to Use: Sprinkle food-grade DE around the perimeter of your yard, in damp areas, or near potential breeding sites. It’s most effective when dry. Reapply after rain. Caution: Avoid inhaling the dust.

Bacillus thuringiensis israelensis (Bti)

What it is: Bti is a naturally occurring bacterium that is toxic to the larvae of mosquitoes, blackflies, and no-see-ums. It’s harmless to humans, pets, and beneficial insects.
How to Use: Bti is available in dunks or granules. You can place dunks in standing water sources that you cannot eliminate (like ponds) or sprinkle granules around damp areas. It’s a very targeted and safe method for midge control in water.

Personal Protection and No See Um Bite Relief

Even with the best prevention, you might still encounter no-see-ums. Here’s how to protect yourself and find relief from bites.

Personal Outdoor Insect Repellent

Natural Repellents: Products containing oil of lemon eucalyptus, picaridin (synthesized from a compound found in pepper plants), or IR3535 are effective and considered more natural than DEET.
Essential Oil Blends: You can create your own personal repellent by mixing essential oils (like citronella, peppermint, lavender) with a carrier oil (like coconut oil or jojoba oil) in a rollerball bottle. Apply to exposed skin. Always do a patch test first to check for skin sensitivity.

Protecting Your Home

Seal Entry Points: Check for cracks and gaps in window screens, doors, and foundations. Seal them to prevent insects from entering your home.
Fine Mesh Screens: Ensure your window and door screens are in good repair and have a fine mesh.

No See Um Bite Relief

If you do get bitten, prompt relief is important.

Wash the Area: Clean the bite gently with soap and water.
Cold Compress: Apply a cold compress or ice pack to reduce swelling and itching.
Baking Soda Paste: Mix baking soda with a little water to create a paste. Apply it to the bite for a few minutes to help soothe the itch.
Calamine Lotion or Hydrocortisone Cream: Over-the-counter lotions can help relieve itching and inflammation.
Avoid Scratching: Scratching can worsen the itch, lead to infection, and prolong healing.

Long-Term Solutions for Controlling Biting Midges
