Japanese beetles fly long distances from where they hatched in grassy areas. All they care about is mating & eating. Treating your yard for them will not stop the ones flying in from golf courses & other folks' yards. They love Linden trees, birch & crab apple trees, grapes, rose blossoms & respberries, among others. Brush them off into a cottage cheese container that has water, a couple drops of dish soap & a quick spray of flying insect spray. Some fly back out, but once they've been in the insect spray & soap they will die quickly. Dispose of them in your garden, compost bin or flower beds. I sometimes spray large clusters of them with flying insect killer. Don't ever use the beetle traps. They draw in thousands of beetles from far away. I did that once & gathered 5 gallons of them daily from the 3 traps I set out. A full time job!
