Buy Japanese Beetle traps. They really work.
Japanese beetles are the adult versions of what is commonly called a 'grub'. I would use a pesticide on the lawn and around the problem spots that professes to kill grubs on the label. Kill the larvae and adults won't form.
Make make sure when you buy the beetle traps that you put them away from your house because it attracts beetles also
It can take some time for the milky spore to become effective.
I handpick or shake them off into a soapy mason jar
You might want to consider that as you wait for your milky spore protection.
“Milky Spore begins working as soon as it is applied as long as grubs are feeding. Once grubs are infected they will multiply the Spore by several billion times and spread it further. In warm climates good control can occur in one to three years. In colder areas like New England, three to five years. Once established in a lawn, Milky Spore has been known to last 15 to 20 years.”

Traps will attract more activity to your property. Many users of traps state...
“The number of beetles this catches is astounding. The problem is that it lures many, many beetles to your yard that wouldn't otherwise come to you. The following year, I had at least double the number of grubs in my garden beds and resulting japanese beetles. I've been fighting increased populations of J.B's ever since using this product and luring them to my home.”
Hello. They lay there eggs in the soil so they end up hatching the next year. I flick them off every day. It works but is annoying. Every year I get less and less. I wouldn't use a trap. It just attracts more. They let off a pheromone so more come. Good Luck!
Thanks all, it is a trial!
The Japanese beetle traps work well, they have a pheromone above the bag and the beetles are drawn to it, they fly to and go into the bag to never come out again. Hang this setup far away from your plants you are protecting. After they die you can shake them out and they are reabsorbed into the environment. Going full circle.
