How does a blind person deal with a pesky fly?

I was trying to enjoy my lunch and some pesky fly kept buzzing me. Even though I had a flyswatter he would never land where I could smack him. I would track him flying, then lose track of him, not here him, think he was gone, and then he would buzz again. I got to thinking if it is that hard for me to get a pesky fly I can see, how does a blind person deal with a pesky fly? Even if they did have a flyswatter handy, if they were alone, it would not do them any good as they could not see the target. Would the blind person be at the mercy of the fly until someone came to their aid?
