Hi, we were in San Pedro this past March. We had no problems with bugs in on our beach or in town at all(although we were prepared with a big can of 31% DEET!) I think the bugs stayed away at the beach because Ramon's (where we stayed) rakes the beach everyday and there is a nice constant breeze. We had stopped at Captain Morgan's for a drink on our golf cart ride up north. One of the people I was with got a few no-see-um bites. After one snorkel stop (I haven't figured out if it was at Goff's Caye or by Caye Caulker) I broke out in what I later figured out (thanks to this message board) was a pica pica rash. It was kinda nasty looking but wasn't too bad and cleared up in about a week.
