We bought bug spray on our trip in November. Total waste of money. I don't think we used a drop. I'd be surprised if they are an issue now. Then again, you didn't say if you were sailing or land based. I think the only place you'll have any possible issue would be on the beach at dusk. This is coming from the "canary in the coal mine" of skeeter persons. I am always the first one to get bit, they just love me for some reason.

Buy a small bottle of deet bug spray when you get down there, just as insurance. Don't bother to bring it, it's not hard to find. If you end up using the first bottle, then go ahead and get more.
