Top 5 Best Insect Repellents in the USA (2026 Guide)
Mosquitoes, ticks, biting flies, and other insects are more than just a nuisance in the United States. They can also transmit diseases such as Lyme disease, West Nile virus, and other mosquito-borne illnesses. Choosing the right insect repellent is one of the easiest ways to stay protected while enjoying outdoor activities.
Interestingly, there is also a unique historical connection between the United States and Vietnam when it comes to insect repellents. From the legendary DEET-based “Bug Juice” used by American soldiers during the Vietnam War to Vietnam’s famous Golden Star Balm, both countries have played a role in the story of insect protection.
In this guide, we’ll explore that connection and review the five best insect repellents available in the United States today.
A Fascinating Link Between Vietnam and American Insect Repellents
The Story of DEET and the Vietnam War
Today, DEET remains one of the most effective and widely recommended insect-repellent ingredients in the world. Although it was originally developed by the U.S. Department of Agriculture in 1946, its reputation grew significantly during the Vietnam War.
American troops operating in Vietnam’s tropical jungles faced constant exposure to mosquitoes and other biting insects. High-strength DEET repellents, often nicknamed “Bug Juice,” became essential equipment. Their success in protecting soldiers helped establish DEET as the benchmark for insect repellents in the United States.
Even decades later, many of the most effective mosquito and tick repellents on the market continue to rely on DEET-based formulations.
Golden Star Balm: A Vietnamese Product with a Loyal American Following
While DEET traveled from America to Vietnam, another product made the journey in the opposite direction.
Golden Star Balm, a traditional Vietnamese herbal balm made with ingredients such as peppermint, cinnamon, cajeput oil, basil oil, and camphor, has developed a surprising following among American consumers.
Many users appreciate it for relieving headaches, minor aches, insect bites, and itching. On online marketplaces, the small metal tins have earned thousands of positive reviews thanks to their portability, affordability, and distinctive herbal scent.
Although it is not classified as a primary EPA-approved insect repellent, many travelers and outdoor enthusiasts keep it on hand to help soothe insect bites after exposure.
