I found mosquitos to be a true menace in Thailand. Many hotels have nets over the bed, but you only need one sneaky mosquito to get in there before you close the net around the bed for your body to become a personal lunchbox. As soon as the hotel cleaners changed the bedding, we did our best to close the nets around our bed. Time and time again I still ended up with bites all over my arms and legs.
There were points during my time in Thailand when I got absolutely eaten alive. A fair bit of experimenting occurred during that time, but one thing remained a constant: I refused to use deet-based repellant.
Why deet is bad for your health
What alternatives did I try
Vitamin B1 supplements
Pure Lemongrass spray
Insecto spray & lotion
What came out the best?
Vitamin b1 & lime juice.
