10 Best Insect Repellant For Travel 2025 in the United States

The Thermacell Mosquito Repellent E-Series Rechargeable Repeller offers a hands-free way to keep mosquitoes away in a 20-foot radius, making it a great choice for travelers and outdoor enthusiasts who want to avoid sprays or lotions. Instead of using traditional chemicals, it creates a protective zone using a repellent refill that is scent-free and flame-free, which is ideal for people sensitive to strong smells or open flames.

The rechargeable battery lasts about 6.5 hours per charge, so it’s handy for daytime or evening use but may require recharging for extended outings. Its electric nature means there’s no sticky residue or need to reapply like with sprays, and it’s proven to work against tough mosquitoes that carry diseases like Zika and West Nile Virus. However, since it’s designed for outdoor use, it’s not suitable for indoor protection.

While it is water-resistant enough to be used outside, heavy rain might affect its performance. This product is well-suited for those who want safe, easy, and odorless mosquito protection without the mess or strong chemical scents common in sprays, especially during travel or outdoor activities.

The Thermacell Rechargeable Mosquito Repeller Refills offer a convenient and effective way to protect yourself from mosquitoes while traveling or enjoying outdoor activities. These refills work with Thermacell’s rechargeable devices and create a 20-foot zone of protection without the need for sprays, DEET, or open flames, which is especially appealing if you want to avoid sticky or smelly repellents. The active ingredient is part of a proprietary formula that is EPA registered, meaning it has been tested for safety and effectiveness against mosquitoes that can carry diseases like Zika and West Nile Virus.

The repellent is scent-free and produces no smoke, making it comfortable for extended use around people and pets. You simply insert the cartridge, turn the device on, and it begins working within 15 minutes, providing up to 12 hours of protection per cartridge—ideal for a day of outdoor activities. Because it is a heating-based system, it doesn’t rely on skin application, so there’s no concern about skin sensitivity or irritation. However, it is designed for outdoor use only and doesn’t offer water resistance, so it may not be the best choice in heavy rain or wet environments.

The refill size is small and easy to carry, but you will need to have the compatible Thermacell repeller device to use it, which is an additional purchase. This product is suitable for travelers or outdoor enthusiasts looking for a fuss-free, chemical-free mosquito shield that avoids sprays and sticky lotions, though it may not be ideal if you need protection in wet conditions or prefer a wearable repellent.

The Thermacell Mosquito Repellent Rechargeable Adventure EX-Series EX90 is a solid choice for travelers and outdoor enthusiasts looking to avoid mosquito bites without applying sprays directly to their skin. Instead of using traditional DEET-based lotions, it creates a 20-foot zone of protection by gently diffusing a scent-free liquid repellent. This means you don’t have to worry about any sticky residue or strong smells on your body, which is a big plus if you have sensitive skin or dislike the usual insect repellents. The device is rechargeable and can run continuously for about 9 hours on a single charge, making it well suited for a full day of outdoor activities like camping, hiking, or backyard relaxing. It’s also lightweight and portable, with practical features like rubber armor for durability and a carabiner for easy attachment to backpacks or belts.

One of the standout benefits is that it has no smoke or flames, which makes it safer and more convenient than some other repellent options. The refill cartridges last up to 12 hours, providing good value and convenience. However, it’s important to note this is an outdoor-only device and won’t protect you indoors or in windy conditions where the protective zone can be disrupted. Since it uses a proprietary liquid formula that’s EPA reviewed, it’s effective against mosquitoes known to carry diseases like Zika and West Nile virus.

The actual concentration of the active ingredient isn’t specified, so it’s hard to compare strength with other repellents directly. Also, while it’s scent-free, some users might prefer a product that also repels other biting insects like ticks or flies, which this device doesn’t explicitly cover. Considering these points, the Thermacell EX90 is ideal for travelers and outdoor users who want a hassle-free, skin-friendly mosquito barrier without sprays or chemicals applied directly, especially in calm outdoor settings.
