Identification of Problem
Whenever possible we like to sit outside in the nice Thailand warmth. This is often in the early evening which can be a prime time for mosquitos to be airborne. They are, of course, attracted to human pheromones and so using a deterrent such as a lit mosquito coil is a good way to hopefully avoid being bitten. These can be readily bought from Big C, Makro, 7-11, Villa market, markets or online.
The coil gives off a scented smoke which mosquitos typically do not like. The coil is held in place by a simple, very cheap, thin piece of flat stamped metal (steel) that acts as a holder. Whilst this simple holder is effective in that it holds up the coil it can often blow over; leaves ash everywhere; can rust outdoors; and often when used a number of times will simply snap as the metal 'fatigues' at the bend point.
