Compared to Dengue, BD probably has much lower prevalence of malaria cases. The only person I know personally who contracted malaria is an army officer posted in a camp in Khagrachhari. Apart from him, I know at least ten other people who had Dengue in Dhaka city (including my mother).
Eitherways, as a layman I would probably buy a bottle of Off! spray, come to bd, smear it on myself and do the holidays.
However given that I live in BD, I prefer using my hands to kill the damn things.
