Hey- when we were down last week I didn't use any bug spray at all and maybe got 3 or 4 bites the entire week- I actually thought they were from the ants I saw but I guess not. Do these sand flies get worse towards the end of the year? like a season thing or do they just get nastier when it rains? I'm usually a beacon of scrumptiousness to mosquitoes back home so I was pleasantly surprised that there weren't a lot of bugs on our trip.
