What’s Kills No See Ums? 

No see ums are tiny bugs that usually hang out around stagnant water. Many people think they are just like mosquitos, but they are actually much smaller to easily go through clothes and mosquito screens.

No see ums bites don’t really hurt, but the next morning you will find lots of itchy bites. You might confuse the no see ums bites with those by poison ivy, spiders, or mosquitoes.

So, No See Ums Repellent is a product that will keep no-see-ums and other insects like biting gnats, black flies, and mosquitoes from biting people. They come with great smells that are safe on your skin and pets.

Most repellents are used to stop no-see-ums from approaching and landing on your skin – thanks to their unique scent. You can find these repellents in golf shops, marinas, independent pharmacies, and resorts.

The no see ums can go unnoticed for up to 15 minutes and often carry tete virus.


Picaridin is a good ingredient for repelling mosquitoes and no see ums. It can be in a 20% concentration in the spray to give you protection against both.

Such a concentration offers a balance between side effects vs. protection. After each application, it will last for about 4 hours.

So, your best no see ums repellent:

  • Repels no see ums and other biting insects.
  • Safe on skin, pets and the environment.
  • Widely available in golf shops, marinas, independent pharmacies and resorts.

Any Risk with DEET No-See-Um Repellents?

The spray that has DEET in it might make you feel sick. But if you don’t use this spray as directed by the EPA, then you might not be safe at all.

If you put DEET on your skin, it can be bad for your immune system and nervous system. This could make you have seizures and be nervous.

Therefore, you should use natural ingredients such as Citronella oil or lemongrass oil.

Do not use sunscreen and DEET at the same time. The sunscreen will make the DEET go into your skin faster, and it will also lose its ability to protect you from UV rays.

Alternative DIY No-se-ums repellents? 

1. Geranium rose oil:

Geranium oil is a good ingredient in repellents for the insects that bite, like ticks and no see ums.

Geraniums are made of organic ingredients (organic and pure rose geraniums) which are not toxic to humans. It has a pleasant smell that will stay with you for hours and is also used in many other bug repellents on the market today.

They balance skin pH levels and open up skin pores so they work well with repellents.

  • Geranium oil can be applied as an insect repellent or diluted into your skincare products such as lotions and shampoos, which will provide protection for either two or four hours.

2. Citronella oil:

Citronella oil is made from the leaves and stems of lemongrass. Lemongrass usually has a lot of geraniol, citronellol, and citronellal.

You can use citronella oil to protect yourself from bugs. But it is not as good as DEET. Vanilla can help extend the protection time. It is often found in vanilla beans or in the CO2 extract.

If you like making candles, this is something to explore. If not, consider buying no see um repellents with citronella such as

  • Cutter-Citroguard Triple-Wick
  • TIKI-1418014 Brand 17
  • Murphy’s-Naturals Mini

3. Lemongrass oil:

You can try burning lemongrass oil using oil lamps to see if it will help keep the no-see-ums and Sand Flies away – that is one reason why it is in some mosquito repellents.


Mix ¼ cup of witch hazel together with ¼ cup of distilled water and Lemongrass Essential Oil (Aura Cacia Organic – 21 to 26 drops).

This can be sprayed on your clothing, body, or exposed skin surfaces in order to repel insects from biting you – as noted by the Entomology & Nematology Department.

4. UV light and CO2 luring:

CO2 is used to lure the no-see-ums with a favorable respiration zone. You can attract the insects using carbon dioxide to move to an area treated with an insecticide and thus kill them.

CO2 mosquito traps – they have CO2 in them. They attract all the bugs that are just like mosquitoes. Bugs come close and then get sucked into the vacuum tube, where they die from dehydration.

5. Special garments:

To avoid insects from getting into your clothes and biting, you should wear special clothes that have a net that keeps them out.

When your vacuum cleaner is not enough to keep the critters away, you can protect yourself with long pants and long shirts, as well as by switching on the air conditioner.

6. Small Mesh Screening

Mosquitos can get into your home through open windows. You can stop them with screens on all the windows in your house.

The small mesh screens are able to stop tiny bugs that people can’t see including no see ums.
