Actually it's better not to use the traps. They will bring Japanese beetles from miles around, more than you would have if you didn't use them. It's best to go out in the morning and knock any into a container of soapy water.

Japanese beetles feast on about 400 different plant species. According to Arbor Day, Linden is one of their favorites. I have read that lilacs are not usually bothered.
