My favorite natural bug spray for golf is from a brand called Alni Body Care. It's made with lemongrass and basil essential oils. It's turf safe and super effective against all itchy, biting bugs, like mosquitoes, horse flies, no-see-ums, gnats. Made by a golfer! Since I started using it, I haven't gotten a single bite! And it also works at the beach! Best Natural Bug Spray for Golf with Lemongrass and Basil
