Yes and No. There actually arent many mosquitos at all....BUT.....we do get sand flies depending on the season, rainfall, dryness, and all those other wonderful jungle factors. They affect everyone differently, so if your the type that gets bitten alot no matter what, make sure to bring up some long pants and repellant. The most effective repellant can be bought in the city and is called NOPIKEX. You need to buy from a pharmacy or large grocery store and it comes in soap form and spray. Ask for it by name, its the most effective against sand flies.
