Last year they released millions of those huge black flies up here to combat Gypsy Moths a couple counties over. It was terrible on the course. Thankfully they didn't do that this year. Black Flies are definitely the most irritating for me. Getting bit 3 times while trying to putt.
I usually do 100% deet on the bill of my hat and 40% on the rest of me and works pretty well for the most part on the other bugs. They usually opt for my less protected playing partners
