Japanese beetles are emerging, and there are early indications that populations are well above normal in some areas. Upcoming rain will soften the soil and spur more emergence.
When practical, hand removal is an effective way to control this insect on a small scale. Remove beetles daily at about 7 PM and knock them into soapy water or use some other means of termination. Left to their own devices, happily feeding beetles release an aggregation pheromone that will attract more and more hungry insects.
