This sign was at one of the cenotes where we snorkeled. Since these are like caves, there were oodles of bats as well as some other cave-nesting birds (motmots and swallows) that probably eat mosquitoes. So it could be that they would like to preserve the mosquito population for the critters (though I doubt a couple dozen people swatting mosquitoes would affect the mosquito population!). The more likely explanation is that they don't want you to use mosquito repellent, which could affect the water quality of this very sensitive ecosystem. You are not supposed to use sunscreen either, but then you don't really need it since you're in a cave most of the time.

lph, matar is "to kill" in Espanol.
