10 Best Deet Insect Repellents 2025 in the United States

The Repel 100 Insect Repellent is a potent choice for those needing serious insect protection. With a high DEET concentration of 98.11%, it excels in repelling mosquitoes, ticks, gnats, biting flies, chiggers, and fleas, even in heavily infested areas. Its formulation provides up to 10 hours of protection, making it ideal for extended outdoor activities without frequent reapplication.

The pump spray is conveniently sized for travel, ensuring ease of use on the go. Since it's unscented, it may be more suitable for those sensitive to strong smells but might not appeal to users who prefer a fragranced repellent. Additionally, while the product is effective, the high DEET concentration can be harsh on sensitive skin, so it's not the best option for those with skin sensitivities.

Repel 100 is best suited for individuals seeking robust and long-lasting protection in severe insect conditions, especially for outdoor adventures.

This makes it particularly suitable for adults and children who spend extended periods outdoors, such as hikers and backpackers.

The formulation is a pump spray, which allows for easy and efficient application, a convenient feature for those on the go. Additionally, the product is unscented, which can be a plus for users who are sensitive to strong smells or prefer not to have a lingering scent.

However, it is worth noting that the product does not specifically mention water resistance, which could be a drawback in wet conditions or for users engaging in water-related activities.
