How To Get Rid Of No See Ums

Smaller than mosquitoes but delivering a similar (or sometimes even worse) bite, no see ums are an obnoxious pest you’ve probably encountered more than once during the spring and summer months.

For many of us living in the United States, no see ums have simply become a staple of the warmer seasons. Of course, that doesn’t mean we need to normalize putting up with them each and every day.

If you’ve had enough of biting no see ums and are at your wits end with finding a solution, then you’ve come to the right place. We are here to help you learn how to get rid of no see ums and go over the best products, methods and home remedies you can use to reduce infestations while also protecting yourself and your loved ones from the no see ums’ itchy and annoying bites.

Let’s get started.

What Are No See Ums?

Pic 1 a no see um against red
No see ums are a small flying pest that are known to bite and leave painful, itchy bumps.

Also known as biting midges, biting gnats, sand flies, and punkies, no see ums are small biting insects scientifically referred to as Ceratopogonidae. They belong to a family of flies that include over 6,000 species.

These flying bugs are common throughout the entire world save for colder regions like the Arctic and Antarctic. And while they can be found nearly everywhere, they prefer regions rich in humidity and are often found clustered in swarms near stagnant water sources.

As their name suggests, no see ums are very small, ranging in size from 1 to 3 millimeters long. Though nearly invisible to the naked eye, no see ums can leave behind a bite on human skin that is painful, itchy, and often considered worse than the bite of a mosquito!

Furthermore, it can take hours and sometimes days before your body reacts to these bites, making you question when and where you even got them.

Do you think you have no see um bites? Think back to when you were out and about in the last few hours or days. These pests are most active at dawn and dusk, and are commonly found swarming in clusters known as clouds.

Only females no see ums bite, and they do so because they are seeking food sources rich in iron and protein (aka, your blood). Of course, no see ums don’t only bite humans. They also like to feast on the blood of pets and livestock as well.

While no see um bites can hurt, they aren’t known to transmit diseases to humans in the United States. Some tropical varieties of no see ums have been reported to spread disease to people and animals, but in America, the biggest threat no see ums bring is the nasty welts they can leave behind on your skin.

Unfortunately, it’s tough to identify a pest you can hardly see. Furthermore, when you do get a closer look at no see ums, they tend to look an awful lot like small mosquitoes. So, how can you identify no see ums for sure?

Let’s find out.

How To Identify No See Ums

Pic 2 a drawing of a no see um
No see ums can look similar to mosquitoes, though they are generally much smaller. 

While mosquitoes and a few other types of small, flying pests are known to swarm, no see ums buzz about in dense clouds and are most commonly found during dawn and dusk. They are also commonly found flying around near stagnant bodies of water or other food sources like livestock.

However, if you aren’t looking for these no see um clouds, you may not realize you have encountered the insects until you have been bitten. Their bites hurt right away but, as we mentioned above, the welts or bumps left behind by these bites may not turn up until a few hours or even a few days later.

Luckily, there are some different ways you can go about repelling no see ums and protecting your yard and loved ones from their painful bites. But before we discuss which products and methods work best, it is helpful to also understand what no see ums are attracted to so you can work on making your home and property less hospitable to them.

What Attracts No See Ums To Your Yard?

No see ums cannot survive or breed without stagnant water sources. 

Like most pests, no see ums are attracted to food sources, a good breeding ground and shelter. They must have water to breed and live, so they are often found near stagnant water sources where they can mate and lay their eggs.

Is your yard buzzing with no see ums? If so, you may also have or be near a few of the below attractants:

  • Ponds
  • Bird Baths
  • Yard Ponds
  • Bogs
  • Swamps
  • Marshes
  • Over-Watered Flower Beds
  • Over-Watered Flower Pots
  • Streams
  • Overgrowth
  • Overturned Tires Filled With Water
  • Overturned Trash Can Lids Filled With Water
  • Buckets
  • Moist Sand Boxes
  • Muddy Soil
  • Porch and Garden Lights

No see ums are also attracted to the carbon monoxide their food sources (you, your pets and other animals) exhale.

In fact, no see ums can smell carbon monoxide from up to 200 meters away! This smell alerts them that a food source is near and can attract a number of no see um pests from far away. While male no see ums do not bite and prefer nectar and tree sap, females need blood, which is rich in iron and protein, to help support their reproduction cycle.

While no see ums in the US are not known to be dangerous to humans, they are annoying and their bites can certainly be irritating and painful. But don’t worry. We have a few tips and tricks you can use to get rid of no see ums for good.

How To Get Rid Of No See Ums – Most Popular Methods

No see um bites can be painful and itchy, but luckily many remedies work to prevent them. 

If you’re overwhelmed by an abundance of annoying no see ums, the good news is that there are several methods you can use to get rid of them. Some of the most common and popular methods used include natural methods, home remedies, and insecticides.

Professional help is not generally required for no see um control, as these are typically outdoor pests who can be controlled using a number of the below methods and products.

Natural Methods

We love using products that contain natural ingredients whenever possible for pest control. When it comes to getting rid of no see ums, using natural products can be especially ideal for those with people and pets in and around the home.

Natural products are typically free of harsh chemicals and are therefore generally safer to use for people, pets and the environment. These products can include sprays, repellents, and sometimes even fly traps and bug zappers.

Home Remedies

If you like the idea of organic pest control, you may also like using a few home remedies to get rid of no see ums. While not all home remedies include the use of organic and natural ingredients, many do.

Better yet, using home remedies to get rid of and control the no see ums on your property can help you save money and time. It’s a win-win!


Very large no see ums infestations may require the use of insecticides and chemicals like DEET. While this is not always the first choice for those who prefer using natural remedies, sometimes insecticide sprays and repellents are the most effective when it comes to reducing no see um bites and controlling large infestations.

But before you decide which type of method or product would be right for you, let’s go over a few methods you can use to get rid of no see ums from natural products, home remedies, and insecticides.

How To Get Rid No See Ums Using Natural Methods

Not all species of no see ums bite and many can be beneficial to the environment.

No see ums are certainly annoying, but keep in mind that not all species of no see ums bite and many species of no see ums are essential and beneficial to a healthy environment. That said, those that do bite can pack quite a punch for such a small pest.

As we mentioned above, using natural products to get rid of biting no see ums and protect yourself from no see um bites is an especially attractive prospect to those who are fans of organic pest control or for those with pets and children.

One of the benefits of using natural methods to control no see ums is that they are generally safer for people, pets and the environment. Furthermore, they are often just as effective in defending against no see ums as chemical sprays, though they may not last as long.

If you’re all about do it yourself pest control, then this is the section for you. Let’s begin with the best essential oils you can use to deter no see ums and go over a few of our favorite no see um repellent recipes.

Dish Soap and Vinegar No See Um Trap

  • 2 drops of liquid dish soap
  • ½ Cup of Apple Cider Vinegar


Pour the vinegar and mix two drops of liquid dish soap into a bowl. Mix the solution until it is sudsy and leave it out where you have noticed no see um activity. The no see ums are attracted to the smell of apple cider vinegar and drown in the soapy water.

However, remember that liquid dish soap can be toxic to pets and children if ingested so use this method with caution around kiddos and animals.

How To Get Rid of No See Ums Using Essential Oils 

Many people find that essential oils are a safe and natural way to repel pests like insects, spiders, rodents and more. When it comes to no see ums, the best essential oils you can use to repel them include:

  • Lavender Oil
  • Citronella Oil
  • Garlic Oil
  • Peppermint Oil
  • Lemongrass Oil
  • Eucalyptus Oil
  • Tea Tree Oil

You can use essential oils to repel pests by dabbing oils like peppermint oil on the wrists, neck, and ankles can help keep no see ums from biting. You can also make your own essential oil no see um repellent spray by following the below recipe:


  • 5 to 10 Drops of The Essential Oil Of Your Choice
  • Two Cups Of Water
  • 1 Spray Bottle

Pour the water into a spray bottle and then add 5 to 10 drops of the essential oil of your choice along with a few drops of liquid dish soap. Shake the bottle until the water is sudsy and spray this spray at the no see um clouds. The soap will kill the pests on contact and the scent of the essential oil will keep other no see ums at bay.

You can also forgo the dish soap and use the essential oils as a repellent you can spray on yourself, your clothing, and even around your yard to repel these pests. Just make sure you test the essential oil you want to use on a small part of your skin first to ensure you do not have an adverse reaction.

Vinegar And Essential Oil No See Um Repellent Recipe  

Another recipe we like to use against no see ums and other pests like mosquitoes is vinegar and essential oil spray. While no see ums are attracted to apple cider vinegar, you can use white vinegar mixed with essential oils to kill these pests on contact.

Take a look.


  • 3 Tablespoon of Citronella Oil
  • 1 Tablespoon of Eucalyptus Oil
  • 2 Cups of White Vinegar

Mix the above ingredients in a spray bottle and shake the bottle until it is thoroughly mixed. The above vinegar and oil spray can be sprayed directly on no see um clouds to kill these pests on contact. It is also an excellent perimeter spray. That said, do not spray this solution directly on garden plants or on your skin, as it can cause irritation.

Chemical bug sprays containing DEET are often preferred because they last longer than two hours.

While we always love the idea of using natural products and home remedies to get rid of no see ums and prevent no see um bites, sometimes a large infestation around your home or property can require chemical sprays or repellents. Furthermore, if you want a spray or repellent that lasts longer than two hours, chemicals may be a better call for you.

DEET  and other types of chemical repellents have proven especially effective when it comes to getting rid of no see ums for longer periods of time.

Let’s take a look at some of the best products you can use to get rid of no see ums as recommended by experts.

  • Ageratum
  • Lemongrass
  • Pennyroyal
  • Peppermint
  • Rosemary
  • Lemon Thyme

Remove Excess Water Sources 

Remember, one of the biggest attractants for no see ums and other pests like mosquitoes are excess, stagnant water sources. These water sources are also breeding grounds for no see ums, which can lead to larger infestations on your property.

Remove excess water sources like buckets, old tires, bird baths, dog bowls, kiddy pools and more.

Do Not Over-Water Your Lawn Or Garden

Overwatered gardens and lawns can attract no see ums and other pests. Furthermore, overwatering your garden can be bad for plant life. Only water your yard and gardens as needed, and keep an eye on flower beds to ensure they are not overflowing with water after rainfalls or watering sessions.

Landscape and Keep Your Lawn Cut Short

Overgrown yards can lead to an abundance of yard and garden pests like mosquitoes, no see ums, rodents, snakes, spiders, and mites. To help reduce the number of pests in your yard and prevent bites from no see ums, we suggest keeping your yard landscaped. Remove weeds, mow the lawn, and keep your garden nice and tidy.

Caulk and Seal Entry and Exit Points and Install Small Screened Windows

While no see ums are generally an outdoor pests, they can become problematic if they get inside. Unfortunately, no see ums are extra small and can sometimes fit into the holes of some screens. Try installing smaller-woven screens in windows as well as ensuring doors and windows shut and seal securely.

Wear Protective Clothing

No see ums are famous for their painful bites and are often considered worse than mosquitoes. However, they are smaller and for this reason cannot bite through clothing. When out and about hiking, gardening, or enjoying your yard during no see um season, you can protect yourself by wearing long sleeves, pants, and hats.

Wear A Bug Spray During No See Um Season When Outside

Whether you choose to wear a natural bug repellent or a DEET repellent to keep no see ums and other biting pests from making a meal of you is up to you, but we highly recommend doing so if you live in an area rich with insect activity, humidity, and stagnant water sources.

Doing this can help protect you from bites, itchy bumps and possibly days of annoying scratching.

Of course, if you do get bitten by no see ums in the United States, don’t panic. These pests are not dangerous or known to spread disease to humans. They are more of a nuisance pest than anything else.

We hope this article has been a helpful guide on how to get rid of no see ums and protect yourself and loved ones from getting bitten this summer.

Stay safe and bite-free out there!
