one reason the chikingunya virus is so nasty is that the mosquito that carries it is not easy to kill. It doesn't breed out of doors but inside buildings, in drains and wet areas etc. So Gov't spraying does no good. On the other hand if you're on a boat you're probably OK. Hotels and restaurants etc are the more likely venue for infection. And they bite by day, not at night.
Actually it breeds in and outdoors and still feeds in the early evening and is up just before sunrise and into the day.
