Used mosquito coils from the mexican grocery again yesterday at Taj Maha before we flew home and didn't get a single bite. They stayed away form us in the gear up area, but did swarm our heads while floating in the cenote since we didn't bring a coil to the water. But with hoods on they don't bug you.Heh. I’m one of those people that gets nice welts from skeeter bites. MX should be fun.
Taj Maha is a very popular training cave. It's also what I think is one of the most underrated caves in mexico. But it is known for its huge mosquitoes, especially the tiger mosquitos that tend to spread more diseases. I would not go there without a coil anymore. The locals actually appreciate you bringing them. I always ask any divers gearing up near me if they are ok with it, as some people cant handle the smell.
