How to Treat No-See-Um Bites

How to Treat No-See-Um Bites

January 16, 2023 53 Comments

No-see-ums are tiny flying insects that are incredibly difficult to spot. Also known as biting midges, punkies, sand flies or biting gnats, these flying insects are small enough to fit through the mesh screens of windows and doors. They are also easy to overlook when they swarm around you or land on your skin. But after they bite, you'll definitely know they were there.

No-see-um bites are painful and itchy, but their havoc can be more than skin deep. Like mosquitoes, these tiny biting insects can also transmit diseases to humans. Luckily, you can minimize your risk of infection and illness by taking care of your no-see-um bites with a combination of over-the-counter medicines and home remedies. These are our top tips for treating no-see-um bites.

How to Treat No-Seem-Um Bites

Insects known as no see ums, biting midges and sand flies fly around in an open field

If you're suffering from painful, itchy no-see-um bites, use these steps to treat them:

  • Pay attention to your bites. They usually look like a small red dot or raised welt that hurts, burns or itches. No-see-ums go after any exposed skin, but they seem to enjoy the back of your neck or legs especially. Look for a cluster of red dots, as it is unusual to have just one bite.
  • Wash the bite thoroughly with warm water and mild soap. Try to wash the area as soon as you notice it to reduce any irritation from the bug's saliva and reduce the risk of infection.
  • It may be hard to resist the urge, but try to avoid scratching your no-see-um bites. Scratching can break the skin's surface and make it easier for infections to develop.
  • Use ice or a cold compress for pain and itch relief. Apply the ice to the itchy welts or spots for 10 minutes or so to numb the discomfort and reduce any swelling.
  • Calm the itch and redness with over-the-counter products. Try an anti-itch steroid or antihistamine cream to soothe any pain, swelling or irritation. You can also take an oral analgesic or allergy medication to stop pain and reduce any reaction.
  • If you don't have any topical treatments at home, make your own by combining baking soda with vinegar or witch hazel. Apply this paste to the bites to lessen any discomfort.
  • If your reaction to no-see-um bites is more severe, including trouble breathing, difficulty swallowing or rashes, you should seek medical attention immediately. Plan to see a doctor if you observe any signs of infection where the no-see-um bit you.

How to Tell No-See-Um Bites From Other Insect Bites

No See Ums, biting midges and biting gnats aren't just outdoors. They can come inside and reek havoc as well

Treating no-see-um bites is similar to what you do for mosquito bites; after all, these biting insects feed on blood to encourage the production and development of their eggs. But how do you know which bug bit you?

First, let's start with gnat and mosquito bites, which often look very similar, causing inflamed, itchy, red bumps on your skin. On the other hand, no-see-um bites may be more clustered and smaller than the other types.

Bug anatomy also plays into the appearance and feel of each bite. Mosquitoes inject their straw-like mouths into our skin to extract blood, often leaving a welt with a puncture wound in the middle. Gnats and no-see-ums "surgically" slice and cut into the skin of their prey with their mouth-based cutters to allow the blood to pool, making it easier for them to feed. This tiny wound can last longer because it is more than a single puncture.

Finally, consider how long each type of bug bite lasts and how they change over time. Mosquito bites are more random, and they can fade quickly. No-see-um bites can morph from small red dot clusters to raised welts lasting almost two weeks.

Frequently Asked Questions About No-See-Ums


Do no-see-ums suck blood?

For the most part, these tiny insects primarily feast on flower nectar as their primary food source. However, female no-see-ums need blood to reproduce and develop eggs.

What happens during the blood-sucking process?
When a female no-see-um bites, she injects her saliva under the host animal's skin, causing the blood to pool and making it easier for the insect to take what she needs.

When are no-see-ums most active?
No-see-ums are most active during dusk and dawn. If you happen to be outside during these times, you are at an increased risk of being bitten.

Do no-see-ums lay eggs in your skin?
If a no-see-um has bitten you, there's little to worry about besides itchiness and irritation. After a blood meal, the female no-see-um often seeks out a body of water to lay her eggs, such as a riverbank, a marsh, a still pond or even a hollowed-out tree stump.

What is the best way to get rid of no-see-ums?

We live near Tampa FL and booked a beach getaway for 10 days to Bradenton Beach/Anna Maria Island, FL. Day 3: woke to dozens of bites!!! Thought the house had bed bugs! NOW I KNOW WHATS BITING ME!! Using many of the remedies posted in this blog…antihistamine for itch relief and topical Cortizone 10, mix of tea tree & lavender oil, putting on DEET spray (not a fan) before going onto patio. Needless to say, very frustrating and these little suckers put a huge damper on my vacation. Thank you for having this information in this blog, most helpful I’ve read in 5 days!

my mother has an infestation of no see ums in her rv. we have tried everything. including local pest control (helped for 1 day). absolutely nothing gets rid of them. the only thing that has helped keep them from taking over the place is i use my floor steamer. i steam closets, ceilings, curtains, cabinets, behind appliances as well as vents. the problem is i can’t do this every day. in the meantime her legs are covered with bites and she looks like a burn victim, her legs are red and swollen, she is elderly and can barely walk. the worst part is she has been to several doctors including specialists and no one believes her. the bites seem infected as a yellowish pus constantly weeps from all the bites. also she uses a hair dryer for intense itching. Vicks vapor rub works best, as well as “repel” in the red can found in the hunting section of Walmart. lemon grass in spray works some. products containing menthol help too. I also used vicks liquid in my steamer a few times which really worked, but the smell got to her. only use a small amount in your steamer. (a small steamer will not work, not enough steam) hope this helps. we are moving her out of that rv soon. only real solution. You can also purchase “demon” from a feed store this is a pest control that you mix with water and use a sprayer to apply. has no odor and when dry is safe for pets. my mother won’t let me use this because of her allergies. when a bug, scorpion or whatever lands on it or walks across they will die. also it will last for up to 6 months. good luck everyone. (we are in central texas).

This is the second time this summer I’ve been attached my noseeumms. The first time I thought it was mosquitos. Then we went back to a remote creek area in AZ and it happened again. Next morning I awake to over 35 bites all over my back. The itching is horrible. My entire back is cover with red swollen makes from the bits. I just happened upon your blog. Until now I had no idea what was biting me. I hate hot showers but I’ll try it to ease the pain and itch.

A bit late to this post, but one of the best remedies for No see um’s is to use a “hotty” – one of those rubber water containers , to warm your belly up. The heat of the hotty is consistent, and gives instant relief – long lasting too :D. Its getting me by nicely – just don’t burn yourself, it can cause blisters.

Someone told me they thought my bites were noseeums but reading your info still has me wondering. They start off with a pinpoint spot. No itching don’t notice it until I see it. Within a week or so it becomes a bigger red scab like spot about the size of a nail head. No itching. It only happens in the summer so I don’t think it is bedbugs or anything like that. I’m at a TOTAL loss! Any ideas? Appreciated thank you

I was at the beach in S Carolina recently and received what I believe to be No-see-um bites. It has been 9 days and since the first bites and 5 days since I left. It seems like new spots are popping up still. I went to the dermatologist to rule out bed bugs, scabies, etc. He agreed they were bites of some sort and gave me some cortisone cream. He said there is a delayed reaction sometimes. Is it possible that new bumps could still be showing up 4 to 5 days out?

Steve, thank you for sharing your tip for relief from itch and pain caused by no-see-um bites. No-see-ums breed and are located near bodies of water or moist soil. They can also be found near wet sand along seashores, so it is best to avoid these areas if you are prone to no-see-um bites. Some additional factors that may increase your chance of being bitten include: body heat, acid production, increased carbon dioxide, genetic factors and potentially blood type. Regarding body odor or fragrances, these do not seem to have a significant impact on whether or not a no-see-um will bite you.

Preventing no-see-um bites? Are there medical conditions such as diabetes that might cause a specific body odor that attracts the no-see-ums? Are specific shampoos and body washes (soap) that should be avoided? Believe it or not, I have found that Vick’s Vapor Rub gives me almost instant relief from pain and itching.

After reviewing no-see-um bites, I believe that is what happened to me. All I know is that it hurt like crazy when I was bit and when I looked down at my ankle I saw a little fly looking insect. I thought maybe it was a miniature bee! I could see a red dot, it swelled, turned bright red, itched like crazy, and spread in diameter (1-2 inches) on my ankle. It’s been two weeks and my skin is discolored still from the bite. I wonder if this should be concerning? This article was very helpful! Thank you!

Was cleaning under a bush the other day and they just came out and attacked me. At first I thought it was allergy to a plant but a lady saw my leg and said, oh my the no see ums got you! I looked at pictures and yes my leg matched a picture. They hurt something awful and itch. I have been doing most of what was written here. Keeping the area clean with warm water and then applying calamine to the area. At night to sleep I take a Benadryl. Left leg not as bad as the right. I also purchased leg and arm covers so when I go out they leave me alone and gives the old bites time to heal. I sprayed the area with flying bug killer hopefully kill them where they live and breed. Wow they itch like crazy and I know they love my blood but this attack was unexpected and I didn’t know! I found a lemongrass deodorant made by Dove and spray myself before going out and notice they don’t like that either. I now feel armed against all flying biting insects. I live in Az so not a year round problem, thank goodness.

I live in Alaska and the no seeums are just awful, beginning in the Spring and going through until September, October when it cools down. Our summers in the capital city are very mild, up to mid 70s in the daytime and down in the 40s at night. I have to wear netted hats and long sleeve shirts and pants when working in the yard. We found that dryer sheets rubbed on the clothes and left hanging out of pockets deters them some, but the saliva they inject when biting causes a real awful reaction on me leaving a huge bump (sometimes the size of a quarter). Peppermint, lavender and tea tree oils sometimes help. Apple cider vinegar I haven’t tried but will after reading one of the above posts. Does your spray have DEET in it? Any other nasty chemicals? If it is organic, I’m willing to try. To respond to a posting, yes these are tiny, dark bugs about the size of a pin head. They don’t seem too active in the early part of the day and get very busy in the late afternoons. I have tried successfully to do most of my yard work early in the day to avoid the worst of the biters.

No see um’s* bite me worse than any mosquito ever! Mosquitoes love me. I moved from Michigan to Florida a year and a half ago. I just went out to water the new sod and within 10 minutes I’m now in the house with my legs bit everywhere! I’m never doing that again without spray on. I’ll be miserable for 2 days!

I have recently been at Vero Beach, FL and got my share of “no-see’um” bites on just my legs from the knees down. The creams and sprays work for a short time, but the best solution for me is get in the shower with a spray attachment and just spray my legs with water that’s really hot. I can then get a good nights sleep. I been doing this for a few days so far, but itching is almost not a issue.

In spite of my best efforts in using protective clothing and repellants, no-see-ums have caused me great misery. In the fall of 2018, I started taking a 1000 mg turmeric supplement for general health reasons. To my surprise, I have not had a single bug bite since. I hadn’t made the correlation until this spring when I knew the bug hatch had to be in full swing. Usually, the no-see-ums find a way to sneak through a button hole or inside a pant leg…but I am bite-free!!

Hi Joe, thank you for commenting and following our blog posts. No-see-um bites can cause welts that may last up to 2 weeks, but it does vary from individual to individual. Since the welts may cause intense itching and scratching, these welts may last longer and may become infected. Please be sure to check with a physician if you have any concerns or possible infection.

As soon as I feel them bite, I rub 100% aloe vera on the area. It doesn’t stop the itching immediately, but within the hour, the bites are totally gone. I am very allergic to them, and without the aloe, the bites will itch for days and days. Aloe is a miracle for me.

I ended up with a welt on the inside of my middle finger what I want to know is..are these blood suckers? if they arn’t why do they bite so hard..it’s itchy and painful..I take an oral antihistamine every day…(and I remember to change my antihistamines from time to time as you can get immune) also hydrocortisone,,,and tea tree cream helps…..I’ve had comments when i’ve had a few welts on my hands from people..and they are surprised when i say it’s no see um bites…mosquito bites i must have immunity cos i don’t notice those at all…I should remind people when they see my blisters that i live on a lake and obviously they like me for some reason..I don’t buy the hormonal thing b cos I haven’t got any female hormones after operation …

Rebecca, thanks for reading and commenting! It can some times be difficult to determine the source of a bite or irritation. When it comes to no-see-um bites they can be extremely bothersome, itchy and in some instances painful. Quite often these bites occur in clusters as a small red dot eventually turning into a welt.

I encountered these black dot insects on the top of Whiteface Mountain, NY. I have learned about them on the internet and this site. The bites stung, the next day is when the welts came up, and the itching. I used apple cider vinegar on a cotton ball and it works good, 100% peppermint oil that works leaving a warm tingle without the itching, and also took a warm shower using the showerhead on the bites to soothe the itch and then followed with cool water. All these were very helpful…not itching for about 2 hours after waking. The bumps do get a “white head” on them, then open with a clear fluid coming out. I reapply apple cider vinegar at this time that stings briefly…but no itch after. Hope this helps others!

A no-see-um (biting midge/sand flea) are the smallest of all gnats and are almost invisible (1-4mm long). The bite can be more painful than a mosquito. It appears as a red spot and may itch at first or cause intense burning. This bite can also form a reddish/whitish welt about the size of a typical freckle.

Need Picture showing no-see-um size. What is biting me is black, About the size of a pencil dot. When trying to capture with packing tape it will not stick and just flies off. Leaves a white sharp pointed pimple if left alone. If scratched and broke open, itching is intense. Seems to take up to 24 hours to form the white tip pimple. Not sure of the species.
