First, let's talk about the difference between DEET and DEET-free mosquito repellents.
DEET, the main ingredient, was first used by the military during World War II to protect soldiers. Since 1957, it has been widely used in American households. The U.S. Environmental Protection Agency (EPA) states that DEET is an effective mosquito repellent for adults and children when used according to the instructions.
The U.S. Centers for Disease Control and Prevention (CDC) further recommends using DEET, registered with the EPA, as the active ingredient to effectively repel mosquitoes that may carry Zika virus, dengue virus, chikungunya virus, and malaria.
DEET confuses receptors on mosquito antennae, making it harder for them to "smell human scent and land on human skin." The concentration of DEET in the repellent determines the duration of mosquito confusion; the higher the concentration, the longer the protection. While DEET provides long-lasting protection against mosquitoes and other pests, it's not the only active ingredient that helps repel mosquito and tick bites from exposed skin.
For centuries, people have used DEET-free products—such as plant oils and other natural insect repellents—to protect themselves in the jungle. In the last two decades, scientists have improved the processes for obtaining these natural insect repellents; for example, PMD is a new, DEET-free option that uses effective mosquito repellent ingredients extracted from natural herbs.
What is PMD?
PMD can be divided into natural PMD, primarily derived from the lemon eucalyptus tree plant extract, and synthetic PMD, processed from synthetic citronellal.
The main ingredient in the herbal PMD formula of Lipa Mosquito Repellent Spray is PMD (OLE), an oil extracted from the leaves and branches of the natural lemon eucalyptus tree. Through a simple transformation process, the oil's main element gradually transforms into P-MENTHANE-3,8-diol (PMD), which is the key component that makes its mosquito-repellent effect longer-lasting than other plant essential oils.
It is highly effective in repelling common tick species associated with Lyme disease transmission. Studies have also shown its effectiveness against mosquitoes, midges, horseflies, sandflies, head lice, cat fleas, leeches, and many other insects and arthropods. It effectively prevents mosquitoes, ticks, flies, midges, and other insects and arthropods.
It is the only naturally sourced active ingredient recognized by the EU for use in insect repellents. The US CDC recommends this as the only naturally sourced active ingredient to prevent mosquito-borne diseases.

How does DEET work?
DEET ( diethyltoluamide) developed in 1944 by the US Department of Agriculture is effective in repelling mosquitoes, ticks, fleas and many other biting insects. DEET works to confuse and interfere with the receptors on a mosquito’s antennae, which deters mosquitoes from landing on the skin and biting. These receptors are used to detect body heat, carbon dioxide and skin chemicals when seeking out prey.
How much DEET do I need ?
It all depends on the person and what you will doing and for how long? The higher the percentage of DEET, the longer the product will remain active. That said, the percentage of DEET doesn’t increase the amount of repelling power, just the length of time it will last. So, Repellun Ointment is (12%) is about 4 hours.
