Do Electric mosquito zappers work?

Do Electric mosquito killers (which work by attracting mosquitoes by UV light) actually work? I have tried 3-4 different models. Two of them worked amazing on first day, but later they stopped attracting mosquitoes. Others never attracted mosquitoes. Is UV light supposed to attract mosquitoes ? Whats the most effective method to take them out ?

Thanks.
Since nothing automatic is working, I have resorted to use mosquito racket which actually works.
