While most pest control methods deter insects, geraniums can attract Japanese beetles. These insects love to eat geranium flowers, despite it producing negative effects that leave them extremely vulnerable. If Japanese beetles are already pestering your plants, having a separate flower bed with only geraniums may encourage the bugs to migrate there. Once they start eating the flowers, they will become immobilized, and other predators will have an easy source of food.
It’s important not to grow the geraniums with the plants being harmed by Japanese beetles, as this could bring more of them to the area. If you don’t want to use up a whole flower bed, you could place potted geraniums around your outdoor space, as long as they’re not too close to your other flowers or vegetable garden. Keep in mind that the beetles will munch on the geraniums and that the flowers will retain some damage, but so will the insects.
