When I went in May, I came back to the states covered in a red rash from sand fleas. They left dark marks but I used a corrector and they aren't visible. This time I came prepared and I only got bit once by a mosquito

The spray I had I got in Jamaica made by a company called "Bunny" which contained 20% deet. I realize they are terrible near Sunbeach and CocoLaPalm...I hope this helps!
