We do of course get mosquitoes, but they should not be a problem unless you sit outside at Kailasam after dusk, without using mosquito repellent. The beach restaurants are free from mosquitoes at night
It’s a good idea to bring long trousers and long-sleeved blouses/shirts, and light-coloured clothing if you are prone to being bitten.
We have mosquito nets on the windows at Kailasam, and over the beds – to help you get a good night’s sleep.
Some people recommend taking a course of Vitamin B1 before and during their holiday – it seems to work for some people. Those who react strongly to bites might like to consider taking a daily antihistamine such as Piriton (also available in Kerala) – it doesn’t stop the bites but your body reacts less.
