How Does It Work?

The Sawyer Products 20% Picaridin Insect Repellent is an insect repellent derived from piperine in pepper plants.

Piperin repels a variety of pests, including flies, gnats, mosquitoes, and ticks.

What I Like

Non-Greasy and Virtually Odorless

Unlike DEET products, Picaridin is not greasy and virtually odorless on the skin.

The lotion evaporates when dry, making it feel seamless on the skin.

 

Won’t Damage Plastic and Fabric

This repellant will not damage sunglasses, watches, clothing backpacks, and other synthetic fabrics.

 

Effective and Long Lasting

The Sawyer Products 20% Picaridin Insect Repellent is one of the most effective in the market.

It repels a wide range of insects, including mosquitoes, gnats, and ticks.

It’s also long-lasting and protects against mosquitoes for up to eight hours.

What I Dislike

Too Thick

Because the product is too thick, you’ll have to use plenty to cover a small area of your skin.

2. Sawyer Products Ultra 30% DEET – Best Gnat Repellet With Deet

[amazon box= “B01CJKFK3U” grid=”1″]

Pros

✅Great for outdoors

✅Effective against many types of pests, including gnats, mosquitoes, and ticks

✅Stain-proof and sweat-proof

✅Fragrance-free

✅Long-lasting  – Up to 11 hours of protection

Cons

🚫Can damage plastic and some fabrics

🚫Only comes in lotion form

🚫Not waterproof

🚫Greasy

🚫Contains less DEET (30%) than other similar products

🚫May diminish the effectiveness of sunscreen

🚫Can be harmful if not handled with care

Key Details

  • Active / Main Ingredients: Deet (30%
  • How Long Does It Last: 11 hours
  • Spray or Lotion: Lotion

How Does It Work?

The Sawyer’s Ultra 30 Insect Repellent protects against common pests using DEET.

It also uses liposomes as a control release system. The Liposomes slowly release DEET, making the product long-lasting.

What I Like

Long-Lasting

Thanks to its controlled release system, this product will protect you against gnats, mosquitoes, and ticks for up to 11 hours.

 

Outdoor Friendly

Because this product is sweat proof, you can use it for fun activities outdoors such as hiking or biking.

 

You can also use it on top of sunscreen, making it ideal if you plan to stay outdoors during the day.

 

Effective

The products’ active ingredient, DEET, is one of the most trusted components in insect repellents for decades.

What I Dislike

Low DEET Concentration

This product has only 30% DEET, which is low compared to other similar products on the market.

Other commercially available products come with concentration as high as 90%. 

 

Greasy

Like most lotion with DEET, this product is greasy. It also leaves an oily sheen on your skin.

 

Only Comes in Lotion

Lotions tend to be heavier than sprays when it comes to application. 

You’ll typically need to apply more per unit area for coverage.

You also cannot apply lotion to clothing. But you can spray on your clothes.

That said, lotion tends to last longer on the skin than sprays. So, this may not be a disadvantage to you if that’s what you’re looking for.

 

Can Damage Plastic and Fabrics

DEET is known to damage plastic and fabrics.

In particular, it tends to be damaging on watches, sunglasses, leather, rayon, and Spandex.
