Hello,
Japanese beetles are very active at this time of year. Picking the adults off and throwing them away is an easy but tedious method of removing them. Fine mesh netting is another option.
Chemical treatments are available but can impact valuable pollinators and other plants.
Read the labels thoroughly prior to buying and using.
Keeping the surrounding soil dry will help reduce adults from laying eggs that would eventually become larva that damage roots on many plants.
Once cooler weather arrives the adult activity will dwindle. Eggs however are the changing larvae and winter over under ground waiting for next year.
Here are two links you can review for more life stage details on fact sheets to keep in hand. https://ohioline.osu.edu/factsheet/ENT-46
