The Thermacell Patio Shield E55 Mosquito Repellent is designed to offer effective mosquito protection with a 20-foot barrier, making it suitable for backyard, poolside, patio, and other outdoor spaces. It starts working within 15 minutes and is portable, which allows users to bring it along even when traveling by airplane.

The device is rechargeable with a lithium-ion battery that lasts up to 5.5 hours per charge, and it includes a 12-hour repellent refill. This repellent is DEET-free and doesn't require sprays, lotions, or zappers, providing a scent-free, smoke-free, and flame-free experience, which is ideal for people who prefer not applying chemicals directly to their skin. Additionally, it is EPA-reviewed and independently tested, proving its safety and effectiveness against various mosquitoes, including those that may carry diseases like West Nile Virus or Zika Virus. This makes it pet and family-friendly.

The need to recharge the device every 5.5 hours might be a limitation for prolonged outdoor activities. While it is effective within a 20-foot zone, it may not be suitable for large areas or heavily infested regions. It weighs only 0.8 pounds and is compact, adding to its convenience. Those looking for continuous protection for longer durations might find the battery life insufficient. The repellent refill also needs periodic replacement, which could be an extra ongoing cost.

The Thermacell Patio Shield Mosquito Repeller offers a convenient and effective solution for keeping mosquitoes at bay, especially in outdoor areas like patios, backyards, and poolside. One of its major strengths is the active ingredient formulation, which is DEET-free and scent-free, making it a safer and more pleasant alternative to traditional bug sprays and candles.

The device creates a 15-foot protection zone against mosquitoes, powered by a compact fuel cartridge, and starts working within 15 minutes. Its repellent mats last up to 4 hours each and are easy to replace, ensuring consistent protection without weakening over time. This product is particularly suitable for those who prefer not to apply repellent directly to their skin. It has been independently tested and reviewed by the EPA for safety and effectiveness, making it people and pet-friendly.

The included 12-hour refill provides ample coverage for extended outdoor activities. On the downside, it's designed for outdoor use only, which might limit its application for some users. Additionally, the need to replace repellent mats and fuel cartridges might be seen as a recurring cost. Given its specialized use and effective mosquito protection, this product could be highly beneficial for individuals looking to enjoy outdoor spaces without the nuisance of mosquitoes.

The Sawyer Products SP565 Premium Insect Repellent is a lotion-based insect repellent with 20% Picaridin as the active ingredient. This offers a reliable alternative to DEET, especially effective against biting flies. The concentration of Picaridin provides long-lasting protection, deterring mosquitoes and ticks for up to 14 hours, and flies, gnats, and chiggers for up to 8 hours, making it suitable for various outdoor activities like camping, hunting, and backyard BBQs.

Its non-greasy, quick-drying, and odorless formulation ensures comfort while being safe on synthetic materials such as clothing and gear. Additionally, it is fragrance-free, which is beneficial for those with sensitivities to strong scents. The repellent is also noted for being family-safe, adding to its versatility for use by all age groups.

However, the large 1-quart size may be less convenient for on-the-go use compared to smaller, travel-sized options. Pairing it with Sawyer Permethrin spray for clothing and gear can maximize protection. This product is ideal for individuals seeking a potent, long-lasting, and comfortable insect repellent for a wide range of outdoor activities, though its larger size might not be as portable as some might prefer.
