I will be in MP/AC late March, 2015.
I understand that mosquitoes, at this altitude, should not be an issue(?!). However, what about biting flies/gnats?
A few years ago, I was in the cloud forests of Ecuador. I did not have DEET w me, as my guide told me, "No bugs at this altitude." The first day, I was covered head to toe in black fly bites. Upon my return to the USA, my travel physician said, "These flies/gnats can carry parasites which can cause blindness." Wonderful. After 6 weeks waiting on the blood tests, I was negative. However, while awaiting the results, my doctor thought it best to place me on chemo-like prophylaxis as a precaution. The drugs made me very, very ill; I don't want to go through that again!
So, should I take DEET or some equivalent w me?
