Japanese beetles can be easily removed from plants with your hands. After you remove the pest from the plant, drop it into a bucket of soapy water.


Don't squish the beetle to kill it. Beetles attract more beetles through pheromones, which are so powerful they can attract beetles from a few thousand feet.If you squish a Japanese beetle, you run the risk of releasing the female beetle sex pheromone.
