IR3535 offers similar protection to DEET, another common ingredient used in insect repellents.
While DEET is usually the recommended option for use in countries with a risk of malaria and other insect transmitted diseases, IR3535 is very effective for repelling most species of mosquitoes, ticks and other flying insects here in the UK and in Europe.
IR3535 has also been found to be generally more tolerable than DEET, which is known to cause odour and skin irritation in some cases.
