PROTECT™ Mosquito Repellent is the most effective, maintains the most prolonged effectiveness, and is the safest mosquito repellent available. PROTECT™ Mosquito Repellent is DEET-free and the only multifunction insect repellent available worldwide, not only protecting you from all biting insects but also nourishing your skin with Omegas 3-6-9, vitamin e, and the super-antioxidant Resveratrol.
PROTECT™ Mosquito Repellent does not contain any citral (found in lemongrass and citronella) which has proved both ineffectual and phototoxic in many clinical studies.*
PROTECT™ Mosquito Repellent is the product of intensive research and development, harnessing botanical extracts from across the globe, establishing the most effective and beneficial in an advanced skin-friendly product. PROTECT™ Mosquito Repellent has undergone extensive studies with other leading repellents which have ultimately proven its superiority.
The chart below shows results of independent research when the 3 species of mosquitoes were tested on human volunteers for effectiveness. Icaridin is the active chemical in Bayrepel and Saltidin. DEET (also known as N,N-diethyl-m-toluamide, or N,N-diethyl-3-methylbenzamide) is the active chemical in Off, Jungle Formula, and Lifesystems Expedition sprays. The percentage of mosquitoes which landed on the test subjects’ arm, and the percentage that bit the test subjects’ arm are compared. Only PROTECT™ Mosquito Repellent had 0% mosquitoes landing on skin and 0% mosquitoes biting the subject.

Deet bug repellent ‘toxic worry’
Scientists have expressed safety concerns about insect repellents that contain Deet after observing the chemical’s toxic effects in mammals.
DEET is short for N,N-diethyl-m-toluamide (also known as N,N-diethyl-3-methylbenzamide). It is a member of the toluene chemical family. Toluene is an organic solvent used in rubber and plastic cements and paint removers. DEET is absorbed through the skin and passes into the blood. The Medical Sciences Bulletin, published by Pharmaceutical Information Associates Ltd. reports, “Up to 56% of DEET applied topically penetrates intact human skin and 17% is absorbed into the bloodstream.” Blood concentrations of about 3 mg per litre have been reported several hours after DEET repellent was applied to skin in the prescribed fashion. DEET is also absorbed by the gut. (reported by HEALTH Canada)
“The popular insect repellent DEET is neurotoxic” – The active ingredient in many insect repellents, DEET, has been found to be toxic to the central nervous system. Researchers writing in the open access journal BMC Biology say that more investigations are urgently needed to confirm or dismiss any potential neurotoxicity to humans, especially when DEET-based repellents are used in combination with other neurotoxic insecticides.

* Citral comprises two compounds which are double bond isomers, geranial and neral, and are the monoterpene aldehydes present in many essential oils such as Lemongrass (Cymbopogon citratus), Lemon Myrtle (Backhousia citriodora), May Chang (Litsea cubeba) and Melissa (Melissa officinalis). Both citral isomers, neral and geranial, induce phototoxicity. The monoterpene aldehyde, citronellal, present in Citronella (Cymbopogon winterianus) induced moderate UVB-induced haemolysis in studies on phototoxicity.
