Adult beetles will soon be gone as they move to the next stage in their life cycle. As we head into August the remaining adult beetles will stop feeding on our plants, lay their eggs and die. These eggs become grubs that will hang out in the soil all winter and into spring next year. It seems to be the consensus that there were many more Japanese beetles this year than the last few years and many plants sustained significant damage.
One question we frequently get is if a plant will die because of Japanese beetle feeding. The good news is that if the plant is healthy and relatively mature it will not die from one season of severe Japanese beetle feeding. Healthy plants can withstand a lot of defoliation and although it may look brown and dead, it will recover.
