Do you have native bats in Haiti? (honest question, I just don't know). You have to have enough around nearby to find your habitat. Bats also have socio-religious stigmas and implications you need to deal with, especially in Haiti.
Goldfish are great at eating larvae in any tank or small pond, cheap in the states but probably not an option for you. Even then you still have all the puddles to deal with.
Are there native birds that eat mosquitoes? I would build houses for any native bird that eats any bugs, too.
Or predator insects? or frogs?
If you have the resources, building habitat for all of them would be good in the long run.
Chikungunya is just the latest round of horribleness in Haiti, there will be more.
