Our Comprehensive Buying Guide


When you have to deal with an infestation of insects, you might wonder: what is the best gnat repellent? More often than not, formulas are designed to fight more than just one type of insects, and those that work against gnats may also keep mosquitoes, flies, and other flying critters away. To find the best gnat repellent for humans, read the following guide to point you in the right direction.

Types of products

First things first, you will have to decide on what type of product you want. Is there a spray to get rid of gnats? The answer is ‘yes’. You will find a plethora of such products. Some are created to be applied to your skin and help you when you go hiking or camping. Others are made for indoor use, in the sense that they have to be sprayed in the rooms where the infestations are bad.

You will also find formulas that come in liquid form. These products are usually spread on the ground, and they can be used on yards and lawns. They can be quite useful, and they reduce the population of insects outside, helping you protect both you and your property.

On the market, gnat repellents come in various shapes. One such shape is that of a head net. As you can see, it is entirely different from the products mentioned to this point. A head net is something you wear, and it doesn’t involve spraying chemicals on your skin or inside your house. Depending on what type of product you’re looking for, there are different options available. Not even the best gnat repellent spray will compete with a head net if you prefer the latter.


How natural is the repellent?

One of the things that rightfully worry consumers is how safe a product is for them and their families. You will notice that some products are advertised as the best natural gnat repellent, but what does that mean? In a nutshell, a natural product should be one that doesn’t include any chemicals on its list of ingredients.

DEET is a chemical often found in insect repellents. While effective at keeping bugs away, it can affect people who are sensitive to the ingredient. That doesn’t mean that you should avoid this ingredient at all costs; in some cases, the best gnat repellent might be one that contains it. As long as the concentration is not higher than 30%, it shouldn’t pose any threats.

Natural products are usually based on gnat repellent plants. They are made with essential oils obtained from such plants, like geraniol, lemongrass, and rosemary. One advantage is that they also have a pleasant smell. However, they might require multiple applications.

Other considerations

Whether you’re looking for a gnat repellent for plants and your yard or one that you apply on your skin, some things are crucial for all the various products. For instance, you must get a good deal for your money. Overpaying for such a mundane product is advised against.

Also, you may want to know if the product is safe around pets and children. And that it cannot ruin your clothes when you apply it. All these aspects will play a role in choosing a product for combating gnats and other insects.



Frequently Asked Questions


Q: What do gnat bites look like?

One of the most important reasons people dislike gnats so much and want to keep them away is that they bite, which can be quite unpleasant. Make sure to get a biting gnat repellent if that’s what you’re dealing with, avoiding such problems.

Gnat bites resemble those of mosquitoes a great deal, which is why telling them apart can be difficult. Luckily, the repellent formulas that work against mosquitoes are useful against gnats, and vice versa. They look like small red lumps on your skin, and they will provoke a lot of itchiness.

Some bites even swell up, which is a consequence of the bitten person’s natural reaction. It is not that uncommon to notice the bites developing into blisters filled with fluid. All these characteristics are similar to mosquito bites, so you must fight against such creatures that cause you plenty of discomfort.

Q: Are gnats dangerous?

There are many and various species of gnats living all over the world. But what is a gnat? Since there are both biting and non-biting types of gnats, and some affect plants, while others are a nuisance for humans, gnats are not easy to categorize. They are flying insects, and they prefer to live in swarms, which is why they are not challenging to identify.

As for how dangerous they are, gnats are not that different from other flying insects. First, they can collect and transport pathogens on their feet as they fly from one area to another. If they land on your food, that is how they can transmit diseases.

Some of them bite, and it is through their bite that they can do the same thing. Gnats are unsanitary creatures, hence the danger they represent for human health. When their numbers grow, they can become an unpleasant nuisance.


Q: Why do I have gnats in my house?

Gnats can be annoying, especially when they invade your home. To learn how to get rid of gnats, you need to know a few things about the products that are the most efficient against them. Preferably, you should opt for a formula that interrupts the gnat life cycle, to prevent new ones from appearing.

The causes for the appearance of gnats on your property are multiple. Moisture is one thing that helps them thrive. From garbage cans to leaking pipes, anything can help them grow and multiply. Decaying organic material is another favoring factor. Even something like human perspiration can play a role.

Make sure that you can apply gnat control methods as soon as you notice them flying around. Don’t allow them to multiply, or you’ll end up with a bigger problem on your hands. The good news is that there are many products on the market designed to help you get rid of such infestations.
