In brief: Pick your poison
Spraying does indeed, prevent malaria- this is the reason why malaria is so rarely seen in the United States or canada these days.
However, mosquito sprays don't just kill these bugs, they also affect the environment, leading to mutant amphibians and other wildlife, as well as the disruption of whole ecosystems. Importantly, just like bacteria, mosquitoes become eventually become resistant too.

In brief: Too many mosquitoes
Many researchers are trying newer techniques to rid malaria infected areas of mosquitoes.
Poisoned sugar water, sterile males and other tatics are under evaluation. Simply spraying for mosquitoes is too costly for many conuntries both in $ and toxic side effects (remember ddt?). Hopefully with effective mosquito control and vaccines we'll finlally rid the world of this deadly parasite.

There are vaccines in testing and production which may reduce the problem to some degree but the complexity of the problems and potential solutions is enormous.

Question is- how close are we to a practical vaccine?

In brief: Side effects
Spraying and use of insecticides to get rid of mosquitoes has been tried.
It can be expensive (note most countries with malaria do not have large public health budgets) and can cause side effects (remember ddt?), as well as breed resistance in the local mosquitoes. However it can also be effective. That said, curent efforts at malaria eradication are focused, excitedly, on vaccine development.
