Scent-wise, the Thermacell repeller is a good option for those sensitive to smells because it is scent-free. Although the initial cost is higher than simple sprays, the rechargeable battery and extended protection time may justify the investment for regular outdoor users. For those seeking an easy, clean, and safe method to keep gnats and mosquitoes away in outdoor spaces without applying chemicals on skin, this Thermacell repeller is a solid choice.

The Thermacell E-ZoneGuard Patio Mosquito Repeller offers a convenient and chemical-free way to keep mosquitoes and gnats away from your outdoor space. Instead of sprays or lotions, it uses a rechargeable device that creates a 20-foot zone of protection by gently heating a DEET-free refill. This means no sticky residues or strong smells, making it great for people with sensitive skin or those who dislike typical insect repellent scents. The device runs on a lithium-ion battery for about 5.5 hours and includes a 12-hour repellent cartridge, allowing for several hours of protection during outdoor activities like patios or camping. It’s simple to use — just press a button, and it activates within 15 minutes without smoke or flames, making it safer around kids and pets.

The coverage is limited to a 20-foot radius, which works well for small to medium spaces but might not be enough for larger areas. Also, the battery life means you may need to recharge if you plan to use it for longer periods outside. Users generally appreciate its effectiveness and ease of use, though some note that it’s best suited for light to moderate mosquito and gnat presence rather than heavy infestations. For those seeking a fuss-free, scent-free, and DEET-free mosquito repellent for outdoor relaxing or light gatherings, this Thermacell device presents a reliable choice.

Most important from

Active Ingredient
Unlike DEET, it doesn't melt plastic and ruin your camera gear, or telescope or whatever else you touch when you are out at night.
Formulation
The pump works great, though the pump handle and stroke is very long, so a full pump gives you a huge amount of the lotion.
Duration of Protection
This stuff is awesome. It's far more effective, lasts longer, feels cleaner, and is more affordable than other alternatives.
Skin Sensitivity
It has proven to be far superior to other sprays and lotions we've tried. No smell, no rashes, no side effects.

The Sawyer Products SP565 Premium Insect Repellent is a lotion-based repellent featuring 20% Picaridin as the active ingredient. Picaridin is known for being effective against a variety of pests, including gnats, mosquitoes, and ticks. One of the standout features of this product is its long-lasting protection, offering up to 8 hours of defense against gnats and other pests, which is quite impressive for outdoor activities like camping, hiking, or backyard BBQs.

The formulation is non-greasy, dries quickly, and is fragrance-free, making it comfortable to wear without the off-putting scent common in many insect repellents. Additionally, it’s safe for use on both skin and various materials, which means you can use it on clothing and gear without worry about damage. It's also notable that it's recommended for family use, making it versatile for different age groups.

However, while the 1-quart pump dispenser is convenient for large families or frequent outdoor adventurers, it might be cumbersome for individual users or those looking for a more portable option. Additionally, even though it's fragrance-free, some users who prefer a scented product might find this feature lacking. For those with particularly sensitive skin, it’s always a good idea to do a patch test first to ensure there are no adverse reactions. In summary, the Sawyer Products SP565 offers robust protection against gnats and other insects, with a user-friendly formulation and family-safe ingredients, making it a strong choice for outdoor enthusiasts seeking reliable and long-lasting insect repellent.

Buying Guide for the Best Insect Repellent For Gnat

Choosing the right insect repellent for gnats can make a significant difference in your comfort and health, especially if you spend a lot of time outdoors. Gnats can be quite bothersome, and an effective repellent can help you avoid their bites and the potential irritation or infections that can come with them. When selecting an insect repellent, it's important to consider several key specifications to ensure you get the best product for your needs.
Active IngredientThe active ingredient in an insect repellent is the chemical that repels the gnats. Common active ingredients include DEET, Picaridin, and natural oils like lemon eucalyptus. DEET is highly effective and long-lasting, making it suitable for heavy gnat infestations or extended outdoor activities. Picaridin is also effective and has a more pleasant smell and feel on the skin. Natural oils are a good choice for those who prefer a more natural product, but they may need to be reapplied more frequently. Choose an active ingredient based on your preference for effectiveness, scent, and skin sensitivity.
ConcentrationThe concentration of the active ingredient determines how long the repellent will be effective. Higher concentrations provide longer protection but can be harsher on the skin. For DEET, concentrations can range from 5% to 100%. Lower concentrations (5-10%) are suitable for short-term exposure, while higher concentrations (20-30%) are better for extended outdoor activities. For Picaridin, concentrations typically range from 10% to 20%. Choose a concentration based on the duration of your outdoor activity and your skin's sensitivity.
FormulationInsect repellents come in various formulations, including sprays, lotions, wipes, and wearable devices. Sprays are easy to apply and cover large areas quickly, making them ideal for outdoor activities. Lotions provide more controlled application and can be less messy. Wipes are convenient for on-the-go use and targeted application. Wearable devices, such as bracelets, offer a hands-free option but may not be as effective as topical applications. Choose a formulation based on your convenience, application preference, and the level of protection you need.
Duration of ProtectionThe duration of protection indicates how long the repellent will keep gnats away. This is often linked to the concentration of the active ingredient. Products with higher concentrations generally offer longer protection. For example, a repellent with 20% DEET may provide protection for up to 4-5 hours, while one with 100% DEET can last up to 10 hours. Consider how long you will be outdoors and choose a product that matches the duration of your activity to ensure continuous protection.
Skin SensitivitySome people have sensitive skin that can react to certain chemicals in insect repellents. If you have sensitive skin, look for products that are labeled as hypoallergenic or designed for sensitive skin. Natural repellents with ingredients like lemon eucalyptus oil can be gentler on the skin, though they may need to be reapplied more frequently. Always do a patch test before using a new product extensively to ensure it does not cause irritation.
ScentThe scent of an insect repellent can be an important factor, especially if you are sensitive to strong smells. DEET-based repellents often have a strong chemical odor, while Picaridin has a milder scent. Natural repellents usually have a pleasant, herbal smell. Choose a scent that you find tolerable, as you will be wearing the repellent for extended periods. If you are sensitive to smells, opt for a product with a milder or more pleasant fragrance.
