Benadryl is good for bug bites. They sell it in a topical creme or a roll on stick you can carry with you. I was last in the Caribbean in Sept. and the skeeters were terrible. That was annoying enough but there was also the threat of Dengue fever, which is no picnic.
Around these parts, I'm concerned more about West Nile virus. I'll be sure to wear repellent when I go berry picking in another couple weeks. Yikes. I can't believe the summer is flying by so fast.
