Use curtains or window nets which prevent entry of mosquitos to the house.
Wear dress which covers most of the body. Also there are mosquito repellents available which can be applied on dress materials.
Use mosquito coils or repellents. But you should be aware that prolonged use of these are not recommended. Also ensure adequate ventilation when these are used.
Use of cream or spray that can be applied on skin. This masks body odour and effectively you are invisible from mosquito. Very handy if you are visiting an area where Chikungunya is reported or prevalent.
Fogging at community level can reduce epidemic of such diseases upto great extent.
Take steps to reduce breeding of mosquitoes as ..
Drain all the water collected around your house (for example in a pot or water cooler).
Ensure that drainages etc. are either closed or chemicals are applied which kill mosquito larvae (larvicides).
If there is a pond which contains stagnant water, biological method is best. Fish varieties such as guppy can be introduced in the pond which will eat all the mosquito larvae.
