When I toured from SC to TX last year, I found the insects not to be a factor in Texas once I was away from the coast. The worst living being that affected me in texas was catcus plants. Those suckers must shoot needles into the sides of bike tires on purpose and puncture holes into the bottom of your tent.
I also agree that **** sapiens while camping are the most irritating. It also seems that dogs, mice, raccoons and other critters seem to be attracted to commonly used campsites. And the pisser is a lot of these campsites will want to charge you the same rate they charge an RV for a space, especially state parks.
I just rather stealth camp and shower up at a Truck stop or other public place.
