I have been using the Bayer 3 in 1 this year. It seems to be helping reduce the beetles. I still have some, but less than last year. If I turn the bug zappers on at night, it gets a lot of beetles - both the Japanese beetles and their beige relatives. I read that the traps should be put downwind of your garden. I didn't put any up this year because I don't have a good place to put them. I am afraid that they will draw more beetles to the garden. A neighbor hung one, so it may help. I also dunk a bunch in water daily, they prefer one rose at the moment -Austin's Wildeve. The neighbor kids like to help.
