Insect repellents review

Written by Jerry Mueller

We all enjoy our outdoor activities but without the best insect repellents, there’s no way we’ll be able to walk, climb, hike or do anything else in the woods without feeling uncomfortable when there’s an army of mosquitos out for blood. It’s important to bring an insect repellent with you when you’re going for an outdoor adventure. But the question then lies in what are the best insect repellents?

A good mosquito repellent often means the difference between an enjoyable summer of outdoor fun and three nightmarish months in mosquito hell. But what kind of insect repellent will do the best job of keeping you bite free?

Read on and we will teach you how to find the best insect repellents so that you can enjoy your outdoor trips with no hesitation.

Insect-Borne Diseases

We provide a little information here from the CDC and FDA, so that you’ll get an idea of the diseases that are transmitted by insects.

  • Mosquitoes are carriers for the West Nile Virus and St. Louis encephalitis. Do apply EPA-registered products for effective results.
  • Ticks transmit diseases such as Lyme disease, Rocky Mountain spotted fever, and babesiosis. A combination of active ingredients such as DEET and permethrin-treated clothing would act as a good tick defence.
  • Malaria. To protect travelers from aggressive mosquitoes that carry this disease, you are advised to use repellents, treated clothing, bed netting and preventative pre-travel medication.
  • Zika Virus. Similar to Malaria, the CDC recommends using repellent and other preventative pre-travel medication to prevent the mosquito bites. ‘

The Active Ingredient to Look for In An Insect Repellent

The biggest concern with millions of people is mosquito-borne diseases that spread by these blood-sucking insects. Mosquito bites can cause skin irritation such as red spots and itchiness. This is because of a substance known as an anticoagulant which can be found in the saliva of the mosquitoes. Once the mosquito bites the human skin, the saliva flows into the epidermis. It then leads to skin irritation.

Insect Repellents

In the market, you can’t expect all products to be the same, and that includes insect repellents. You’ll find all sorts of different insect repellents in the form of gel, spray, cream and aerosol. There are also wristbands, but we’re not sure if that’s effective as there is insufficient evidence to prove its effectiveness.

To determine how long can the insect repellent stay effective for, you’ll have to look at the level of concentration of the active ingredient.

Despite a diverse range of products, you can only find that the most common active ingredients that can be easily found in the market are DEET and Picaridin. Both of these ingredients are effective at preventing mosquito bites. However, Picaridin is odourless and so is considered to be more pleasant to use.

Do note that there is some resistance to the use of these chemical repellents. And why is that? It is because they’re unpleasant to use, and they are usually thought to bring damage to clothing or belongings and is believed to pose adverse health effects. According to recent reports, there has been an increasing use of these two chemical ingredients and that there have been no serious adverse reactions reported.

Due to this reason, you’ll be able to find that most insect repellent products that are endorsed by health authorities internationally may contain these two ingredients, labelling it as a safe way to avoid mosquito bites.

Here, you’ll be able to find some information about these two active ingredients.


Since the year 1957, people have been using this active ingredient. It has since become the most commonly used repellent. There have been many reviews stating that DEET is safe to use and that there are no side effects on human health.

The idea is that those products that contain the lower concentration of this active ingredient would mean that you will have to apply frequently for effective results and that if the product consists of a higher concentration of DEET, it’ll be very effective.

Ultrathon with deet

DEET is successfully registered under EPA, so there’s evidence to prove that it is safe to use. You can also try combining DEET with clothing that are permethrin-treated, as they will be able to protect the wearer from ticks.


Another alternative ingredient other than DEET would be Picaridin, and became available in the US in 2005. The maximum concentration of Picaridin would be 20%, and it provides protection for up to 8 hours. Even one of the world’s biggest organizations, the World Health Organization(WHO), has recommended this active ingredient, so it’s safe to say that Picaridin is indeed effective.

The great thing about this active ingredient is that it does not cause damage to any fabric, surface or material. However, do keep in mind that this component is not suitable for kids under two months old.


People often get confused on how the concentration of a repellent determines the level of protection. Just when you’re thinking of keeping those mosquitoes away from you, you’ll have to focus on finding the level of concentration of the ingredient contained in the insect repellent.

Many customers asked the same question: is there a difference between an insect repellent that has a concentration of 80% active ingredient and another with only a concentration of 10% or uses less active ingredient?

Well, hikers who are going to be in the woods for about 6 hours or longer will need the insect repellent with higher levels of concentration. The longer you need to protect your skin from these insects, the higher level of concentration of active ingredient you should be looking for in the insect repellent.

Insect repellent in the wild

When you’re looking to buy the right and suitable insect repellent for yourself, make sure to consider what kind of activity you’ll be needing it for. If you’re only going for a short and quick trip outdoors, such as to your backyard to do some gardening or to the park, you can always go for a low concentration insect repellent, which should be able to do the trick.

As for a major hike, camp or fishing trip which means you’ll be staying outdoors longer, you’ll need to look for an insect repellent with a higher level of concentration.

If you’re wondering whether the formulation matters, the answer is, not really.

The formulation probably doesn’t make much of a big deal here, but the choice of the active ingredient is more of an important decision.

‘Natural’ repellents

Are insect repellents that are made of natural ingredients the best choice? You’ll find that natural repellents are safe to use, but studies have shown that it may cause skin problems.

Do not confuse yourself with essential oils. According to recent marketing strategies, most businesses often have the notion that as long as they advertise the product as a ‘natural’ or ‘chemical-free’ product, they would be able to attract customers and this may mislead them into thinking that these products may be a better option in comparison to products made of chemicals.

As advice, not all ‘natural’ products are as effective as they have been advertised to be, as researchers have yet to come up with conclusive results to demonstrate its effectiveness. Products containing botanical extracts may offer protection, but because it is free from chemicals and purely ‘natural’, you’ll have to apply it more often.

Natural insect repellents may be very popular in the market, but it is no doubt that one of the most popular ingredients, DEET is still the most popular and effective ingredient.

Natural tick insect spray repellent

Have you seen ultrasonic repellents? It’s been very popular in the past few years but one tip on this, it just doesn’t work.

To conclude from this, DEET and Picaridin-based repellents are still the best as they are cheaper and more effective. They’re also able to provide protection from mosquito-borne disease, still, the chemical ingredient that most would go after.

Registered and Unregistered Repellent

Before you’re thinking of making a purchase, do check whether the insect repellent that you’ve picked is a registered product or an unregistered product. Before these products can be put on the shelf of the stores, they must first be registered with the EPA.

There is a diverse range of repellents made of plant oils and approximately thirty of them are exempted from the EPA registration. So not all botanical plant-based or natural based insect repellent would necessarily mean that they’re effective and safe.

Tips for Using Insect Repellents

Insect repellents are only limited to adult and children ages four months old and above. For babies older than three months, we recommend that you look for a child-specific insect repellent.

  1. Do not just spray it as if you’re using a perfume! The effective way would be to spray it evenly on your skin.
  2. Be careful of direct contact with your eyes. To be safe, spray it on your palms and apply it on your skin.
  3. If you’re going to get wet either sweating or going for a swim, you’ll have to apply it frequently.
  4. Consider what kind of activity will you be going for and from there, you’ll be able to tell how long you would want to be protected for. Are you going for a short trip outdoors or a longer trip in the woods? Decide on the different levels of concentration needed for the type of activity.
  5. Try not to wear dark color clothes or perfume as these will attract mosquitoes.

We hope that after reading this, you’ll be able to understand more about insect repellents and that you’re able to come to a decision on what kind of insect repellent you should be purchasing.
