why does every bug zapper on the market have a UV light bulb in it?
Because it works, at least, it makes people think that it does.
The light attracts all kinds of insects, and they surely get zapped and leave a nice collection of carcasses around the device.
If you were to examine these, you'd find that the vast majority of them are insects that will not bite, sting or otherwise harm you - apart from being a nuisance.
I don't have a pool but I do have a bunch of bats around my yard, and some of them have taken up residence under one of the shutters beside my living room window. Our cleaning lady freaked when she heard them because she thought they would fly into her hair, which is of course a myth.
Bats sure gobble up a lot of mosquitos and other insects (if they are the right kind of bat). The part about flying into womens hair is not a total myth though: A big head of hear with curls sticking out wouldn't be all that visible to their sonar, and they can get snagged when they fly over believing they will safely miss your head.
Anectodal evidence seems to confirm this. The 'victims' however mistake this navigational error for an attack, and some believe the bats are out to get and bite them.
