I really don't use anything. Grew up in the back woods w/ mosquitos and black flies where it's really bad. Never had bugs as bad as spring/early summer anywhere else except Alaska. Sometimes I just question the stuff and think it's another thing that people buy b/c it's there. Also quite harmful to put on your body. I don't use anything b/c I kinda got used to having mosquitos and black flies around as a kid. Whenever someone is complaining about bugs I kinda just sit there and think to myself "what bugs, you don't even know about bugs".
