Here’s an American Nurseryman article on the Japanese Beetle. It’s a general introduction to the pest but doesn’t focus on control because many of the controls are controversial or ineffective. The use of traps and the controls you have the ability to do on your property may or may not be effective because the darn pests fly in from a goodly distance away a) if they’re hungry and b) if you have something they like to eat and c) if they’re looking for less competition from other beetles.
This is why an attractant lure needs to be put a long way from your own garden. If you use a lure, you’re bringing in more beetles than otherwise would be in your yard and they all don’t go to the trap. It’s the same thing for predator nematodes (that attack the larval forms). You can control them in your yard but unless all the neighbors do, it’s a waste of time.
