For what it's worth, the wife and I suffered from many fewer bites this year in Negril than past visits. My wife is a mosquito buffet... They rarely bother me, but she has literally had to visit the doctor in Negril on other vacations the bites were so bad. We were told that there was fairly regular spraying when we visited end of November, and most places I frequented were fairly free of any mosquito breeding grounds (standing water).
