Insect repellents

The optimal concentration of D.E.E.T. (N,N-diethyl – 3 – methylbenzamide) is 20 to 50%. It must be freshly applied every 6 hours. CAUTION: children and pregnant women should not use concentrations higher than 20 or 25%. Especially with children there have been seen serious side effects ( convulsions). Experts advise to wash off any D.E.E.T. when there is no longer need for protection. Your best option for protection during the night is a mosquito net: and little children are best kept under the net from sunset till the sun come up again.

Travel Health Tips Sun blocks

Studies show that D.E.E.T. reduces the effects of sun protecting crèmes. The protecting crèmes however do not influence the insect repellent working of D.E.E.T. So the repellent can be administered together with the sun block, but it is advised to take a sun product with a higher level of protection.

The application of sun block is best done 15 to 30 minutes before getting into the sun en has to be repeated every two hours or after swimming or excessive sweating. The mentioned protection is only assured if enough of the product is applied. Once you have been burned by the sun there is no proven treatment that will speed up recovery!
