No matter what bait you use, it doesn't work. Stay away, useless purchase. The electric racket is much better.

Unfortunately, the product does nothing as far as I can tell. It doesn't attract flies. I tried putting honey, sugar, sweet syrup in the traps, but it doesn't attract flies. And now, as I'm writing this, I have three flies on my face, half a meter away from me, and they don't go into the trap. Maybe it needed an infrared lamp in the center to attract insects.
