We were there earlier this month on charter for a week. We had bug spray but never had to use it. I will say some in our group were getting bit at Jumbies. We had a table by the trees. We simply moved tables and had no problems after that.
June 14-23: Lots of mosquitoes at Hodges Creek Marina, a few under the tables at dinner at Jumbies and Scrub. Some occasional no-see-ums. A little bug spray took care of situation everywhere but at HCM.
