Insects, especially the stinging variety, can be bothersome, annoying, and sometimes downright dangerous.
Higher altitudes tend to have lower insect populations, and hence less risk of insect bites.
Avoid open-air eating areas that have exposed food and beverages that might attract insects. Look for eating establishments that are clean and well screened or air-conditioned. Avoid swimming in small ponds or pools of water. Stagnant water is the favorite breeding ground of mosquitoes. Also, mosquitoes come out to feed at dusk, so try and remain indoors during this time.
