10 Best Insects Repellents 2025 in the United States

The Thermacell Patio Shield E55 Mosquito Repellent is designed to create a 20-foot mosquito protection zone, making it a good option for outdoor areas like patios, backyards, and poolside. It works by diffusing repellent in the air rather than applying it on your skin, which is a benefit for those who prefer not to use DEET sprays or lotions. It is scent-free, smoke-free, and flameless, making it a more pleasant option for many users.

The product is independently tested and EPA reviewed, which suggests a certain level of safety and effectiveness. The device is portable and easy to use, with a rechargeable battery that lasts up to 5.5 hours, though the 12-hour refill cartridge will require replacement for continuous use. The lack of scent is an advantage for those sensitive to strong smells. However, users should note that the effectiveness may vary depending on environmental conditions, and the initial setup might involve some learning curve.

It is also on the higher price side compared to traditional mosquito repellents. The product includes a 2-year warranty, extendable to 3 years with registration, which adds an assurance of quality and reliability. This product is ideal for individuals seeking a non-spray, non-scented, and easy-to-use mosquito repellent solution for outdoor spaces.

The Sawyer Products SP657 Premium Permethrin Insect Repellent is a highly effective option that offers robust protection against a wide variety of insects. Its active ingredient, Permethrin, bonds to fabric fibers, making it ideal for clothing, gear, and tents. One of its standout features is its long-lasting effectiveness—up to 6 weeks or through 6 washings. This makes it convenient for extended outdoor activities such as camping, hunting, and backpacking. Additionally, it’s fragrance-free, so it won't interfere with your sense of smell or attract insects with unwanted scents.

The product is particularly effective in reducing the likelihood of tick bites, especially when used on shoes and socks. For maximum protection, it can be paired with Sawyer Picaridin topical repellent for the skin. While the product is safe for fabrics and won’t stain or damage them, it can degrade under UV exposure or through washing machine agitation over time. The spray formulation is straightforward to use, but as it is specifically designed for clothing and gear, it may not be suitable for direct skin application, which requires an additional product for comprehensive protection.

The Sawyer Products SP657 is an excellent choice for those who need reliable, long-duration protection against a wide range of insects. It's particularly useful for outdoor enthusiasts who need to treat their clothing and gear rather than their skin directly. While it requires occasional reapplication due to washing or UV exposure, its effectiveness and ease of use make it a top contender in the insect repellent category.
