Why use an insect repellent?
For most people being bitten is an itchy annoyance, but it can be much more serious. Mosquitoes can carry infectious diseases such as malaria, yellow fever, dengue and Lyme disease.
It is therefore important to take sensible protective measures to prevent being bitten - the use of an insect repellent is a good first step.
Precautions for high risk destinations should be discussed with your Doctor prior to travelling.
