Being an expat, especially from the continent you might notice, that Mauritius has quite humid air. Normally places close to Equator or located in the Ocean have extremely high humidity level. It creates some special rules for living, if you don't want mold and fungus enter your home, live inside your closet and slowly kill all your favourite things, including clothes, shoes, and even technical devices!
I've done little research on this matter, and based on my experience, here are some advices:
1) Fungus will grow in the places with limited air access and absence of sun light. Warmth and darkness are the best friends of fungus.
So at your home regularly open the windows to ventilate and let sunlight in. Do the some for your closet.
2) if you sweep the floor, make sure you clean it dry right after.
3) Don't let your wet things inside your home, better to dry it outside.
4) Be simple. Try to allocate minimum number of furniture, and create space in between pieces of furniture and walls, so air can go everywhere.
5) Even pillows and mattresses can be damaged by mold, so don't forget to bring them outside from time to time.
Regarding clothes.
Don't let your clothes stay at your wardrobe, unworn. Bring it outside from time to time under sunlight.
Don't put wet clothes into closet.
Better to iron all clothes before putting it in wardrobe.
To make air drier in the closet, install little lights inside. I heard (but haven't tried yet), coal, rice, salt are good at absorbing humidity.
Be careful with leather stuff (jackets, shoes, bag, belts etc). It can be easily damaged by mold.
6) Try to keep your technical devices in use all the time, otherwise you're in danger to loose them.
Hope it will help some of you. For me, humidity is a kind of big issue, cause when I saw some of my things started to be damaged by mold, it really upset me, as I don't want to loose my beautiful and favourite things especially clothes. Does anybody of you face this problem? Do you know other ways how to deal with humidity?
