Understanding PMD: A Powerful Natural Insect Repellent

The quest for effective insect repellents is as old as human civilisation. In modern times, this has led to the development of various synthetic and natural agents to protect us from the annoying and potentially harmful bites of insects. One such natural agent that has emerged as a potent repellent is PMD. But what exactly is PMD, and why is it a preferred choice for many?

1. What is PMD?

PMD stands for para-Menthane-3,8-diol. THEYE Ltd uses Citrepel 75 which is the strongest and most refined PMD available, it is a naturally occurring compound derived from the extract of the Java Citronella plant. Over the years, PMD has gained attention as an effective insect repellent, particularly against mosquitoes.

2. The Rise of PMD

The need for natural insect repellents grew due to concerns about the synthetic chemical DEET. DEET (N,N-Diethyl-meta-toluamide) has been a primary active ingredient in many repellents since the 1950s. However, while DEET is effective, it comes with a range of issues like potential skin irritations, plastic degradation, and a strong odor. This opened the door for alternative repellents, and PMD emerged as a leading contender.

3. Why PMD?

There are several reasons why PMD-based repellents have found favor among users and researchers:

  • Natural Origins: As a compound derived from the Java Citronella Plant, PMD appeals to consumers who are keen on using natural products.

  • Efficacy: Numerous studies have found PMD to be comparable to DEET in repelling mosquitoes and some other biting insects such as midges, ticks and horseflies.

  • Safety: PMD is considered safe for use on the skin. While all repellents, natural or synthetic, can cause allergic reactions in some individuals, PMD generally has a lower risk profile compared to DEET.

  • Pleasant Scent: Many users find the lemony scent of PMD repellents to be more appealing than the strong odor associated with DEET-based products.

4. How to Use PMD-Based Repellents

When using PMD-based repellents:

  • Follow Directions: Always read and follow the label directions. This ensures maximum effectiveness and safety.

  • Reapply as Necessary: Like all repellents, the effectiveness of PMD can diminish over time, so it may be necessary to reapply, especially if you notice that insects are beginning to bite.

  • Avoid Contact with Eyes: Take care to avoid contact with the eyes, mouth, and other sensitive areas.

5. Considerations

While PMD is a promising alternative to DEET, it's essential to remember:

  • Not for Everyone: Some individuals might have skin sensitivities or allergies to PMD. It's always wise to patch-test any new product to check for reactions.

  • Range of Efficacy: PMD is effective against mosquitoes, midges, ticks and other biting insects so can be used in all environments. 


The world of insect repellents is vast, but PMD has established itself as a reliable, natural alternative to traditional repellents. As with all products, the key is to be informed, choose what aligns with your needs, and always prioritise safety. Whether you're planning a camping trip or simply want to enjoy a summer evening outdoors, PMD-based repellents can be a great tool in your armory against pesky insects.
