Highly recommend DEET. I'm bringing several bottles of it when I come down in two weeks. I fly a mosquito control helicopter in Florida so I have learned all about what is effective and what isn't. DEET works, use it and keep the bugs away.

That being said, I hope you're doing well. Those Bot fly's are nasty. I hear whiskey helps it heal faster. I'm no doctor but I stayed in a Holiday Inn sometime in the last ten years.
