Combating the mosquito issue is a project that requires the co-operation of the people as well as support and financing from the government.
One of the biggest causes of mosquito infestations is trash. A mosquito larvae can live in a drop of water on an empty chips packet, discarded cans, bottles, tyres, buckets etc.
Even if we aerial spray, ground spray and treat our drinking water and well water supplies so that mosquitos cannot breed we will still need to combat the trash problem and the overgrown land in populated areas.
We can't eradicate the mosquitoes but we can begin to control the situation if we are all willing to do our little part.
Remember, stay indoors during the times of day when the mosquitoes are most active - this is around dawn and dusk. Wear repellant.
