The farther south you go, the less likely bug spray will do anything useful. Poison ivy, poison oak, poison sumac... sand spurs, sand fleas... different types of skeeters that carry different types of diseases and all of them prefer different times of day/dark... gator tastes great but don't let the wildlife officer know you killed it.
Maybe too far south for the info you're looking for, lol. What are hellbenders?
