Health expert Yvonne Bishop-Weston Nutritionist London says "The issue is not so much whether this particular toxin is dangerous but how it interacts in human body the with the cumulative cocktail of toxins in our modern lifestyles. There's little actual scientific proof that individually they affect our fertility and nervous systems or have an effect on escalating cancer rates but it's basic common sense to avoid these toxins where possible. The residues from non organic food we eat, the water we drink, cosmetics we use and the chemicals used in our workplace and at home all add up. It's good living assurance advice as opposed to ill-health insurance. Look for Deet Free Alternative Insect Repellents!"

The study reported by the BBC in the open access journal BioMed Central Biology shows deet works in the same way as paralysing nerve gases used in warfare.

Deet (N,N-diethyl-meta-toluamide) was developed by the US Army in 1946 following its experience of jungle warfare during the second world war, then registered for use by the general public in 1957.Deet has been in use for decades and is found in most of the commonly used repellents to ward off mosquitoes.

About 200 million people use deet-based repellents every year and over 8 billion doses have been applied over the past 50 years.

The researchers also found that deet interacts with carbamate insecticides, used in agriculture, increasing their toxicity.

In research deet blocked an enzyme called acetylcholinesterase, whose job is to control one of the main chemical messengers used by the nervous system.
