THere are Costa Rica government or tourism sites that can tell you when mosquitoes are at there worst and how to prevent bites. I wear a bug spray with deet in it because it seems to work the nest for our family but there are bracelets and other gadgets that may be just as eccectfull.
We have travelled to the jungles and the beaches and were the deet where ever or where ever we go.
We were there in December. No mosquitoes that we saw !
