Sadly there are no habitable places in the United States or on earth that doesn't have any mosquitoes though that would be nice.
No matter where you go in the United States you're gonna get bugs and mosquitoes because bugs and mosquitoes thrive in all states.
The warmer it is the more bugs and mosquitoes there will be and we can help control the population of mosquitoes but there's no way to get rid of 100 percent of the mosquitoes.
The only places on earth that do not have any mosquitoes are Antarctica and Iceland and those places are really cold and would be good places to visit for a few days or so but not to live.
Those places stay cold year round and you would not get outside much.
I hate mosquitoes but there's no way I would move to Antarctica and Iceland to get away from them.
You can use a fan outside to blow the mosquitoes away from you or use a mosquito magnet to help suck in the mosquitoes and kill them.
