Those huge mosquitoes aka mosquito hawks do they bite?

and I mean bite humans, not mosquitos coz apparently they eat humans. I'm terrified of mosquito hawks, and I'm too afraid to kill them coz I'm afraid they'll fly around me. I just saw one in my bathroom and now it's gone so I'm freaking out so I want to know do they bite people? Or are they just a pest that just flies around doing nothing but eating mosquitoes?
