Buyer’s Guide – Best No See Ums Repellent

What’s a No See Ums?

First, no see ums are little biting nuts that you can barely see and breed around stagnant water. Many people confuse them with mosquitos, but they’re definitely smaller than they can go through clothes and mosquito screens. No see ums bites don’t really hurt, but you wake up the next morning with very many and itchy bites. 

People think that they’re being bitten, in their sleep, by bed bugs. It’s just like spider bites or poison ivy – the no see ums don’t show right away – it takes some time. Sadly, no see ums will carry disease such as tete virus

So, No See Ums Repellent is a product designed to stop or control no-see-ums and other insects like biting gnats, black flies, and mosquitoes from biting people. Luckily, they come with amazing smells and are safe on your skin and pets

Most No See Ums Repellents are designed to produce a scent that’ll stop no-see-ums from approaching or landing on your skin. You can find the repellents in golf shops, marinas, independent pharmacies, resorts. 

What’s in the no see ums repellent? 

1. Picaridin – Picaridin is endorsed as a great ingredient for no see ums’ and mosquito repellents. A 20% concentration in the repellent would give you a great balance for minimal side effects vs. no see ums protection. Also, after each application, you can stay protected for about 4 hours. 

3. Geranium rose oil – Geranium oil is proven to be an effective ingredient in repellents for no see ums, ticks, and lice. Its created from rose geraniums (organic and pure) with decongesting skin pores and balance the skin PH. 

4. Citronella oil – The next essential oil, Citronella, is extracted from stems and lemongrass leaves. Lemongrass offers the composites geraniol, citronellol, and citronellal mainly used in soaps and perfumes. It’s a great ingredient when used in the no see ums repellent. 

5. Lemongrass oil – You can burn some lemongrass oil and try whether it’ll repel the no see ums – that’s the reason why it’s used in these repellents. 

What Are the Risks of No See Ums Repellents

Right away, I have to state that any no see um repellent that contains DEET exposes you to a significant amount of health risk or side effects – if not used as directed by EPA.

If absorbed in your skin, DEET can damage your immune and nervous systems, causing seizures and nervousness. 

Therefore, you must consider it with natural active ingredients such as Citronella oil or lemongrass oil.

You must also not use DEET combined with sunscreen as the latter would increase the rate of DEET absorption. Further, the sunscreen would significantly lose its ability to reflect UV rays. 

How do no-see-um and their bites look like?

No see um bites: Like mosquitos, it’s the female no-see-ums who will suck blood from human beings. The females inject some saliva under your skin, which causes blood to coalesce near the skin. This results in an itchy red bump – which grows into a (roughly 2 inches’) welt. Here’s how to treat no see ums.

Like I mentioned above, the females will get some damp places such as wet sand or muddy areas, hollow and wet trees where they’d lay their eggs. The eggs hatch and develop into adults after 28 days, after which they take flight. 

No see um: Sandflies, punkies, biting gnats – these insects (the no see ums) originate from the Ceratopogonidae family, and they mainly bite human’s knees downwards. No-See-Ums (known as biting midges) are mainly found in the coastal areas.  Like their mosquito counterparts,  No-See-Ums prefer moist places as locations to lay the eggs. 

On food, male and female No-See-Ums eat sweet juices and nectar. However, females No see ums also suck blood (from human beings and domestic or wild animals) to enhance the egg production process. 

The Entomology and Nematology Department UFS defines no-see-ums, known as midgies, Ceratopogonidae, punkies, or sand flies, and are in Diptera order. Their wings have thick hairs creating coloration patterns that are used to identify their species.

Stated, no-see-ums are tiny flies that will bite you painfully, but you can barely see them, and that will breed around stagnant water.

How to prevent no-see-ums bites

You can eliminate no-see-ums through window screens, special garments, repellents, and CO2 luring and killing.

1. Repellent Sprays: The Entomology and Nematology Department UFS experts state that repellents with DEET can readily repel no-see-ums. According to the CDC, you can use Picaridin-based repellents as they are safe and effective compared to DEET

These are the DEET produced no see um control products to help repel the bugs from human beings. Further, you should wear tall socks and long sleeve shirts while also switching on the air conditioner. 

2. 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 release CO2 (an attractant) to attract no see ums just like mosquitoes. When the bugs come near the trap, they’re sucked by the vacuum and are dehydrated to their death. 

3. Special garments: To avoid the insects from slipping into your loose clothes and biting you, you’ll need to clad with special no-see-um-proof netted clothes. Now, let’s jump into the various repellents that you can use to avoid bites by no-see-um.

4. Small Mesh Screening –  These act as a physical barrier to entry of No-See-Ums that aim at attacking human beings. The small-mesh screens are known to offer some tighter weave, and hence it’s able to stop the tiny bodies no see ums.  


There you go; I hope you can now make an appropriate choice on the best Repellent for the no-see-ums that have been terrorizing you. However, it would be effective you combine the wipes with any of the other spray repellents. Happy shopping.
