10 Best Insect Repellents 2025 in the United States

The Thermacell Rechargeable Mosquito Repeller Refills offer a convenient and effective way to keep mosquitoes at bay. One of its standout features is the creation of a 20-foot protection zone within 15 minutes, making it suitable for outdoor activities without the need for sprays or flames. It operates using a heat-activated, rechargeable lithium-ion battery, providing up to 5.5 hours of continuous protection per charge, which is relatively long-lasting for many outdoor excursions.

The lack of DEET, scent, smoke, or harsh odors makes it a more pleasant choice for users with skin sensitivity or those who prefer a scent-free environment. Additionally, it is safe for both people and pets, which adds to its appeal for family use. The refills are easy to replace, and the product is compatible specifically with Thermacell E-Series and Radius devices, ensuring it works seamlessly with these models. However, it is not compatible with fuel and mat-powered repellers, which could be a drawback for some users.

The product is portable and airline-friendly, adding to its convenience for travelers. On the downside, the effectiveness of the repellent may vary based on the environmental conditions, and the 5.5-hour protection per charge may require frequent recharging during extended outdoor stays. Despite these minor drawbacks, the Thermacell Rechargeable Mosquito Repeller Refills provide general satisfaction with its performance and ease of use.

The Thermacell Patio Shield E55 Mosquito Repellent is a convenient and effective device designed to create a 20-foot mosquito-free zone. It offers a no-spray, scent-free solution that works quickly, providing maximum protection within 15 minutes. The device is rechargeable, featuring a lithium-ion battery that lasts up to 5.5 hours on a single charge. This makes it ideal for use in backyards, patios, and even poolside, as it's portable and can be taken on airplanes.

The product includes one repeller, a 12-hour repellent refill, and a USB charging cable, making it easy to set up and use right out of the box. One major advantage is that it repels mosquitoes without the need for skin-applied sprays or lotions, which can be a significant benefit for those with skin sensitivity or who prefer not to use DEET-based products. The repellent used is independently tested and EPA reviewed, making it safe for both people and pets.

However, the need to replace repellent cartridges could be seen as a drawback, as it adds ongoing cost and maintenance. Additionally, while it is effective within a 20-foot range, its protection is limited to this zone, which might not be sufficient for larger outdoor areas. Despite these minor drawbacks, the Thermacell Patio Shield E55 stands out as a strong option for those seeking a hassle-free, portable, and efficient mosquito repellent for small to medium-sized outdoor spaces.

Repel 100 Insect Repellent is a strong and effective spray designed to protect against a wide range of biting insects, including mosquitoes that can carry serious viruses like Zika and West Nile. Its main strength lies in the very high concentration of DEET (98.11%), which is known to provide reliable and long-lasting protection, up to 10 hours in this case. This makes it a good choice for people spending extended time outdoors in heavy insect areas.

The product is unscented, which is a plus for those sensitive to fragrances, and it comes in a convenient, travel-friendly 1-ounce spray bottle that’s easy to carry. The spray form is straightforward to apply and dries quickly. However, because of its high DEET content, it might not be suitable for people with sensitive skin or for use on young children without caution.

This pack of six is great for families or groups who want reliable insect protection during camping, hiking, or travel. If you need a potent repellent that works for many hours and targets multiple pests, Repel 100 represents a solid option, but make sure to avoid overuse on delicate skin and consider alternatives if you need water resistance.
