No doubt, Repel 100 Insect Repellent is one of the best gnat spray bug repellents on the market.

It contains 98.11% percent DEET formula that is responsible for its bug repelling effect.

If you’re going outdoors like hiking, then you wouldn’t want to reapply the repellent on your body again and again. Repel 100 solves this problem. It gives you 10 hours of protection from various kinds of bugs, whether you’re facing a mosquito problem, or you’re getting annoyed with the gnats, this product will deal with them.

Note: This is one of the most effective gnat bug sprays that you can find online. But, a lot of people don’t buy it because they just look at the product description on the top. And, unfortunately, the Company didn’t mention that it repels gnats also. They only talked about mosquitoes. A lot of people think that, it only works on mosquitoes. But, this is not true. If you see the product image, further scrawl down the page, or even look at the customer reviews, you’ll find that, how effective this product is in gnat repelling.

Repel 100 is designed for easy handling & portability. They only sell up to 4 oz. pack. They designed it for the outdoors, so you can easily keep it in your bag.

It works great.

But, there is a catch!

It’s too oily. Some users also relate it with like; you’re rubbing paint on your body. It also doesn’t smell good. You’re not going to like its smell.

Even, some users suggest that, go to the balcony or outdoors for spraying it on your body. When you’ll rub it on your body, you’ll not like the smell, and then you’ll love your decision that before spraying, you come outdoors in the fresh air.

As it contains 98.11% DEET, therefore, the Company recommends that you should keep it out of the reach of children.

I’ll not suggest you use it on kids. However, use it on their clothes is okays, but don’t use it on their direct skin. If you want to use a DEET based insect repellent, then use one that contains DEET less than 30%. As mentioned earlier, a high percentage of DEET doesn’t mean, it repels more insects, it means, it’ll last longer.

Pros

  • Highly Effective, repels various kinds of bugs like gnats, mosquitoes, fleas, ticks, biting flies, & chiggers.
  • Gives at least 10 hours of protection.
  • Available in small size, portable and easy to handle.
  • Cheap & Effective. Price will not be the issue for you.

Cons

  • Feels Oily & doesn’t smell good.
  • Not a good choice if you want a product for children.

The Conclusion

As mentioned earlier, according to a study done by EPA (Environmental Protection Agency), DEET doesn’t cause any harmful effect on normal usage. That makes it safe to use.

It is very effective, and will give you at least 10 hours of protection.

If you are going outdoors, then Repel 100 Insect Repellent is a great choice for you. Its scent is not good and it feels oily, but in just a few minutes, you’ll be habitual of it. So, personally, I think, smell & oily feel are not a deal breaker.

Don’t forget, it’s very cheap. Before making a choice, you should take a look at the thousands of customer reviews of Repel 100, that’ll help you a lot.

Sawyer Products Premium Insect Repellent with 20% Picaridin


Sawyer Premium Insect Repellent is a gnat bug repellent that contains 20% Picaridin, instead of DEET. This is the best bug spray for gnats.

The World Health Organization (WHO) recommends the active ingredient Icaridin (or Picaridin) as the product of choice for the malaria prophylaxis. This is also the first choice of Public Health Agency of Canada’s Canadian Advisory Committee on Tropical Medicine & Travel for the travelers in the age of 6 months to 12 years.

The active ingredient Picaridin is odorless & doesn’t feel oily on skin, this is a big advantage over DEET because a lot of people refuse DEET products just because they’re very oily and have a strong unpleasant scent.

Even, there are some studies that show that when used at the same strength, Picaridin repel insects as effectively as DEET.

The Sawyer Premium Insect Repellent effectively repels mosquitoes that can transmit Yellow Fever, Zika Virus, and other insects like gnats, chiggers, biting flies, and others.

After applying it once, the lotion will give protection against mosquitoes for up to 14 hours, while against gnats, flies, & chiggers, it’ll give you 8 hours of protection.

But, when applying it on your skin, then you have to be careful. It can cause moderate eye irritation, so avoid getting contact with eyes. After getting contact with eyes, hold your eyes, and gently rinse with water for about 15 to 20 minutes. If swallowed, then call a physician or a poison control for the treatment advice.

It has fewer harmful effects as compared to DEET, but still, it can be dangerous, so make sure, to keep it away from the reach of children.

How to Apply

As we know, it can cause eye irritation and can cause problems if swallowed. Therefore, when it comes to applying on the face, then don’t spray it on your face. This way, the spray can affect your eyes, nose or ear. The proper recommended way is to first spray it on your palms, and then gently apply it on your face & neck. Don’t apply under clothing.

After handling it, make sure you thoroughly wash your hands.

The Company recommends that, you should not exceed two application of this spray per day.

With Sawyer products, you’ll have two options. You can use a lotion or a spray. But, which is better?

It is very easy to apply the lotion on your body as compared to spray. But, when it comes to protecting your clothing & gear, then spray is more suitable than lotion.

So, I’ll suggest you to purchase both lotion & spray.

But, if you have no problem with a oily product or unpleasant scent, the only thing you want is longer protection against gnats, then you should go with Repel 100 Insect Repellent as it keeps away the gnats and other bugs for 2 hours longer than the Sawyer Products.

With thousands of positive reviews on Amazon, I’ll suggest you that, you should give it a try, if you have never tried any Picaridin based product.

Sawyer Premium Permethrin Insect Repellent

This Permethrin based product not only repels bugs, it really kills gnats, mosquitoes, chiggers, and more than 50 other kinds of insects.

It is as effective as 100% DEET based product.

The repelling and killing effect of this Sawyer product will last for approximately 6 weeks, and it won’t damage your gear, plastics, or any other finished surfaces. It also doesn’t cause any stains on fabrics & clothing.

But, before making a purchase, you should know that it should not be applied on skin. It is only designed to use on clothing, tents, and other gear. But, not on skin.

You may think,

What happens, if I use it on my skin as a repellent, will it work for 6 weeks?

No, it is not a good idea.

First, applying it on your skin can cause irritation, and other health problems.

Second, if you’re not sensitive towards Permethrin, in that condition also, it won’t help you. The Company uses the same ingredient that found in hair shampoos for head lice. Within 15 minutes, human skin will break down Permethrin after getting into contact, and then, it won’t repel & kill bugs.

It becomes odorless after drying, so there is no need to worry about bad scent.

It is not toxic to humans and dogs, but bewares; do not use it on cats. Cats are more sensitive towards Permethrin, and therefore, it is recommended that you do not even apply it near cats.

It is not for skin. It’s for outdoor gear and clothing.

So, use it on your clothing, tent, and other outdoor gear. It’ll create a barrier between you and insects.
