Product Information

There are eight possible stereoisomers. [7] The exact composition is rarely specified and is commonly assumed to be a complex mixture. PMD can be synthesized by a Prins reaction of citronellal. [3]

We do not know the effectiveness of non-EPA registered insect repellents, including some natural repellents. Do not use products containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD) on children under 3 years old. It's particularly vital if you're heading somewhere tropical, where insects can transmit diseases such as yellow fever, malaria and Zika. The only wearable device that fared well in the study was OFF!® Clip-On, which features a nebulizer to vaporize its repellent chemical, Metofluthrin. The sonic repeller and bracelets showed no significant reduction in mosquito attraction.

Whether you're spending summer at home or in warmer climes, insect repellent is important for preventing bites and stings. Each was worn by, used, or applied to a human subject in a wind tunnel near a three compartment cage containing Ae. aegypti female mosquitoes. Each repellent was tested for a 15-minute period, during which time mosquitoes were free to wander from the middle compartment of the cage into either the compartment closer to the human or the one further away. Then, the mosquitoes were counted in each compartment to determine how attracted they were -- or weren't -- to the human wearing the repellent being tested. verifyErrors }}{{ message }}{{ /verifyErrors }}{{

Again, like sunscreen, don't just rely on repellent to protect you. Cover up with clothing, especially if you're prone to bites, as this acts as an additional barrier. The golden rule is (much like sun cream) to apply thoroughly to any exposed skin, before you head out, and re-apply often – especially if you're sweating a lot, or have been swimming. If you need both, remember it's sunscreen first, mossie repellent second. Looking for a natural and clinically proven Insect Repellent to protect against mosquitoes? incognito® protects against all biting and stinging insects including all 3000 species of mosquito, 33 of these live in the United Kingdom. Don't let children apply repellent themselves. You don't want them putting their fingers in their mouths or rubbing their eyes with insect repellent on their hands. Keep away from stagnant water, as this is another place that many biting and stinging insects like to gather (and breed).This 2021 summer there are more insects than ever before because of the excess groundwater combined with high temperatures.a b Drapeau, Jeremy (2011). "Green synthesis of para-Menthane-3,8-diol from Eucaplytus citriodora: Application for repellent products". Comptes Rendus Chimie. 14 (7–8): 629–635. doi: 10.1016/j.crci.2011.02.008. Citronella. This is a popular choice among consumers but research shows that citronella's volatility means its repelling properties only last for a short time (a 57% protection rating after just two hours compared to DEET's 90% over six hours) and there is insufficient information for them to be seen as reliable repellents. With expert insight from Professor James Logan, of the London School of Hygiene and Tropical Medicine, we reveal which types of repellent are scientifically proven to work - and where to buy the cheapest ones. Refined OLE contains approximately up to 70% PMD, a mixture of the cis and trans isomers of p-menthane-3,8-diol. John C. Leffingwell.

Sonic mosquito repellers. These claim to drive mosquitos away with high-frequency sound but, again, studies show that they don't work. Carroll, Scott P.; Loye, Jenella (2006). "PMD, a Registered Botanical Mosquito Repellent with Deet-Like Efficacy". Journal of the American Mosquito Control Association. 22 (3): 507–13. doi: 10.2987/8756-971X(2006)22[507:PARBMR]2.0.CO;2. PMID 17067054. S2CID 225645.

Mosquito repellents that don’t work

PMD is the active ingredient to look for. This is scientifically proven to be as good at repelling mosquitos as the synthetic repellents above, and is the only plant-based option recommended by the Advisory Committee for Malaria Protection (ACMP).
