10 Best Insect Repellent For Gnat 2025 in the United States

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.

The Thermacell Patio Shield Mosquito Repeller is a user-friendly, DEET-free option for repelling mosquitoes, making it an attractive choice for those seeking an alternative to traditional sprays and lotions. Its active ingredient is diffused through a small, portable device that creates a 15-foot zone of protection, which is effective within 15 minutes of activation.

This product is ideal for use in backyards, patios, and poolside areas, making it versatile for various outdoor settings. The repellent is scent-free and does not involve any candles or flames, adding to its convenience and safety, especially around children and pets. The included fuel cartridge powers the device, and the repellent mats last up to 4 hours each, changing color to indicate when they need to be replaced.

These features contribute to ease of use and consistent protection without the need for applying any chemicals directly to the skin, which is beneficial for those with sensitive skin. The duration of protection per mat is relatively short, requiring frequent replacements for extended outdoor use. Additionally, while it effectively covers mosquitoes, it is not specifically tailored for gnats, so its efficacy in repelling gnats might vary. Those looking for a longer-lasting solution or specific gnat protection may need to consider additional options.

The Sawyer Products SP5442 Picaridin Insect Repellent is a solid choice for keeping gnats and other pesky insects at bay. It uses 20% Picaridin, an effective and skin-friendly active ingredient. This formulation is non-greasy and dries quickly, making it comfortable to wear on your skin. Plus, it's safe for use on clothing and various gear items without causing damage.

You don't have to worry about any annoying fragrance since it's unscented, which is a plus for those sensitive to strong smells. This repellent offers up to 8 hours of protection against flies, gnats, and chiggers, which is ample duration for most outdoor activities. Notably, it's also effective against mosquitoes and ticks for up to 12 hours, adding extra value.

However, some users might find applying an aerosol less convenient compared to lotions or wipes. Furthermore, while it's great for a broad range of activities from camping to backyard BBQs, it might require reapplication during extended outdoor adventures. This repellent suits both outdoor enthusiasts and families looking for reliable insect protection.
