Just there two weeks ago...I used bug spray all day and definitely at night. Used skin-so-soft during day for little nats and flies and definitely 30% deet for evenings. One night I forgot to hit my feet and arms at Capricorn and got eaten alive! Fortunately they have some Off on hand. I'm sure you can buy it there but it is extremely expensive. Best to bring your own. Our hotel was spraying every night but I still felt that the bugs were pretty bad, except for on the breezy days.
