Works very well so far (and I haven't used the attractant). Sometimes it takes more than one zap to kill the bug but the majority of them are toast after one hit. Fun to hear it at night (can be quite loud), and makes it a lot nicer in the morning when I get in my car (I have a "California garage" that is open to the backyard). Just wish it was more sturdy to stand up (it's meant to be hung).
